The effect of triangular prismatic elements on the hydraulic performance of stepped spillways in the skimming flow regime: an experimental study and numerical modeling

계단식 여수로는 댐의 여수로 위로 흐르는 큰 물의 에너지를 분산시키는 비용 효율적인 유압 구조입니다. 이 연구에서는 삼각주형 요소(TPE)가 계단식 배수로의 수력 성능에 미치는 영향에 초점을 맞췄습니다. 9개의 계단식 배수로 모델이 TPE의 다양한 모양과 레이아웃으로 실험 및 수치적으로 조사되었습니다. 적절한 난류 모델을 채택하려면 RNG k – ε 및 표준 k – ε모델을 활용했습니다. 계산 모델 결과는 계단 표면의 속도 분포 및 압력 프로파일을 포함하여 실험 사례의 계단 여수로에 대한 복잡한 흐름을 만족스럽게 시뮬레이션했습니다. 결과는 계단식 여수로에 TPE를 설치하는 것이 캐비테이션 효과를 줄이는 효과적인 방법이 될 수 있음을 나타냅니다. 계단식 여수로에 TPE를 설치하면 에너지 소실률이 최대 54% 증가했습니다. 계단식 배수로의 성능은 TPE가 더 가깝게 배치되었을 때 개선되었습니다. 또한, 실험 데이터를 이용하여 거칠기 계수( f )와 임계 깊이 대 단차 거칠기( yc / k )의 비율 사이의 관계를 높은 정확도로 얻었다.

Multiscale Process Modeling of Residual Deformation and Defect Formation for Laser Powder Bed Fusion Additive Manufacturing

레이저 분말 베드 퓨전(L-PBF) 적층 제조(AM)는 우수한 기계적 특성으로 그물 모양에 가까운 복잡한 부품을 생산할 수 있습니다. 그러나 빌드 실패 및 다공성과 같은 결함으로 이어지는 원치 않는 잔류 응력 및 왜곡이 L-PBF의 광범위한 적용을 방해하고 있습니다.

L-PBF의 잠재력을 최대한 실현하기 위해 잔류 변형, 용융 풀 및 다공성 형성을 예측하는 다중 규모 모델링 방법론이 개발되었습니다. L-PBF의 잔류 변형 및 응력을 부품 규모에서 예측하기 위해 고유 변형 ​​방법을 기반으로 하는 다중 규모 프로세스 모델링 프레임워크가 제안됩니다.

고유한 변형 벡터는 마이크로 스케일에서 충실도가 높은 상세한 다층 프로세스 시뮬레이션에서 추출됩니다. 균일하지만 이방성인 변형은 잔류 왜곡 및 응력을 예측하기 위해 준 정적 평형 유한 요소 분석(FEA)에서 레이어별로 L-PBF 부품에 적용됩니다.

부품 규모에서의 잔류 변형 및 응력 예측 외에도 분말 규모의 다중물리 모델링을 수행하여 공정 매개변수, 예열 온도 및 스패터링 입자에 의해 유도된 용융 풀 변동 및 결함 형성을 연구합니다. 이러한 요인과 관련된 용융 풀 역학 및 다공성 형성 메커니즘은 시뮬레이션 및 실험을 통해 밝혀졌습니다.

제안된 부품 규모 잔류 응력 및 왜곡 모델을 기반으로 경로 계획 방법은 큰 잔류 변형 및 건물 파손을 방지하기 위해 주어진 형상에 대한 레이저 스캐닝 경로를 조정하기 위해 개발되었습니다.

연속 및 아일랜드 스캐닝 전략을 위한 기울기 기반 경로 계획이 공식화되고 공식화된 컴플라이언스 및 스트레스 최소화 문제에 대한 전체 감도 분석이 수행됩니다. 이 제안된 경로 계획 방법의 타당성과 효율성은 AconityONE L-PBF 시스템을 사용하여 실험적으로 입증되었습니다.

또한 기계 학습을 활용한 데이터 기반 프레임워크를 개발하여 L-PBF에 대한 부품 규모의 열 이력을 예측합니다. 본 연구에서는 실시간 열 이력 예측을 위해 CNN(Convolutional Neural Network)과 RNN(Recurrent Neural Network)을 포함하는 순차적 기계 학습 모델을 제안합니다.

유한 요소 해석과 비교하여 100배의 예측 속도 향상이 달성되어 실제 제작 프로세스보다 빠른 예측이 가능하고 실시간 온도 프로파일을 사용할 수 있습니다.

Laser powder bed fusion (L-PBF) additive manufacturing (AM) is capable of producing complex parts near net shape with good mechanical properties. However, undesired residual stress and distortion that lead to build failure and defects such as porosity are preventing broader applications of L-PBF. To realize the full potential of L-PBF, a multiscale modeling methodology is developed to predict residual deformation, melt pool, and porosity formation. To predict the residual deformation and stress in L-PBF at part-scale, a multiscale process modeling framework based on inherent strain method is proposed.

Inherent strain vectors are extracted from detailed multi-layer process simulation with high fidelity at micro-scale. Uniform but anisotropic strains are then applied to L-PBF part in a layer-by-layer fashion in a quasi-static equilibrium finite element analysis (FEA) to predict residual distortion and stress. Besides residual distortion and stress prediction at part scale, multiphysics modeling at powder scale is performed to study the melt pool variation and defect formation induced by process parameters, preheating temperature and spattering particles. Melt pool dynamics and porosity formation mechanisms associated with these factors are revealed through simulation and experiments.

Based on the proposed part-scale residual stress and distortion model, path planning method is developed to tailor the laser scanning path for a given geometry to prevent large residual deformation and building failures. Gradient based path planning for continuous and island scanning strategy is formulated and full sensitivity analysis for the formulated compliance- and stress-minimization problem is performed.

The feasibility and effectiveness of this proposed path planning method is demonstrated experimentally using the AconityONE L-PBF system. In addition, a data-driven framework utilizing machine learning is developed to predict the thermal history at part-scale for L-PBF.

In this work, a sequential machine learning model including convolutional neural network (CNN) and recurrent neural network (RNN), long shortterm memory unit, is proposed for real-time thermal history prediction. A 100x prediction speed improvement is achieved compared to the finite element analysis which makes the prediction faster than real fabrication process and real-time temperature profile available.

Abstract

태양열 집열기의 낮은 효율은 CCHP(Solar Combined Cooling, Heating, and Power) 사이클의 문제점 중 하나로 언급될 수 있습니다. 태양계를 개선하기 위해 나노유체와 다공성 매체가 태양열 집열기에 사용됩니다.

다공성 매질과 나노입자를 사용하는 장점 중 하나는 동일한 조건에서 더 많은 에너지를 흡수할 수 있다는 것입니다. 이 연구에서는 평균 일사량이 1b인 따뜻하고 건조한 지역의 600 m2 건물의 전기, 냉방 및 난방을 생성하기 위해 다공성 매질과 나노유체를 사용하여 태양열 냉난방 복합 발전(SCCHP) 시스템을 최적화했습니다.

본 논문에서는 침전물이 형성되지 않는 lb = 820 w/m2(이란) 정도까지 다공성 물질에서 나노유체의 최적량을 계산하였다. 이 연구에서 태양열 집열기는 구리 다공성 매체(95% 다공성)와 CuO 및 Al2O3 나노 유체로 향상되었습니다.

나노유체의 0.1%-0.6%가 작동 유체로 물에 추가되었습니다. 나노유체의 0.5%가 태양열 집열기 및 SCCHP 시스템에서 가장 높은 에너지 및 엑서지 효율 향상으로 이어지는 것으로 밝혀졌습니다.

본 연구에서 포물선형 집열기(PTC)의 최대 에너지 및 엑서지 효율은 각각 74.19% 및 32.6%입니다. 그림 1은 태양 CCHP의 주기를 정확하게 설명하기 위한 그래픽 초록으로 언급될 수 있습니다.

The low efficiency of solar collectors can be mentioned as one of the problems in solar combined cooling, heating, and power (CCHP) cycles. For improving solar systems, nanofluid and porous media are used in solar collectors. One of the advantages of using porous media and nanoparticles is to absorb more energy under the same conditions. In this research, a solar combined cooling, heating, and power (SCCHP) system has been optimized by porous media and nanofluid for generating electricity, cooling, and heating of a 600 m2 building in a warm and dry region with average solar radiation of Ib = 820 w/m2 in Iran. In this paper, the optimal amount of nanofluid in porous materials has been calculated to the extent that no sediment is formed. In this study, solar collectors were enhanced with copper porous media (95% porosity) and CuO and Al2O3 nanofluids. 0.1%–0.6% of the nanofluids were added to water as working fluids; it is found that 0.5% of the nanofluids lead to the highest energy and exergy efficiency enhancement in solar collectors and SCCHP systems. Maximum energy and exergy efficiency of parabolic thermal collector (PTC) riches in this study are 74.19% and 32.6%, respectively. Figure 1 can be mentioned as a graphical abstract for accurately describing the cycle of solar CCHP.

1. Introduction

Due to the increase in energy consumption, the use of clean energy is one of the important goals of human societies. In the last four decades, the use of cogeneration cycles has increased significantly due to high efficiency. Among clean energy, the use of solar energy has become more popular due to its greater availability [1]. Low efficiency of energy production, transmission, and distribution system makes a new system to generate simultaneously electricity, heating, and cooling as an essential solution to be widely used. The low efficiency of the electricity generation, transmission, and distribution system makes the CCHP system a basic solution to eliminate waste of energy. CCHP system consists of a prime mover (PM), a power generator, a heat recovery system (produce extra heating/cooling/power), and thermal energy storage (TES) [2]. Solar combined cooling, heating, and power (SCCHP) has been started three decades ago. SCCHP is a system that receives its propulsive force from solar energy; in this cycle, solar collectors play the role of propulsive for generating power in this system [3].

Increasing the rate of energy consumption in the whole world because of the low efficiency of energy production, transmission, and distribution system causes a new cogeneration system to generate electricity, heating, and cooling energy as an essential solution to be widely used. Building energy utilization fundamentally includes power required for lighting, home electrical appliances, warming and cooling of building inside, and boiling water. Domestic usage contributes to an average of 35% of the world’s total energy consumption [4].

Due to the availability of solar energy in all areas, solar collectors can be used to obtain the propulsive power required for the CCHP cycle. Solar energy is the main source of energy in renewable applications. For selecting a suitable area to use solar collectors, annual sunshine hours, the number of sunny days, minus temperature and frosty days, and the windy status of the region are essentially considered [5]. Iran, with an average of more than 300 sunny days, is one of the suitable countries to use solar energy. Due to the fact that most of the solar radiation is in the southern regions of Iran, also the concentration of cities is low in these areas, and transmission lines are far apart, one of the best options is to use CCHP cycles based on solar collectors [6]. One of the major problems of solar collectors is their low efficiency [7]. Low efficiency increases the area of collectors, which increases the initial cost of solar systems and of course increases the initial payback period. To increase the efficiency of solar collectors and improve their performance, porous materials and nanofluids are used to increase their workability.

There are two ways to increase the efficiency of solar collectors and mechanical and fluid improvement. In the first method, using porous materials or helical filaments inside the collector pipes causes turbulence of the flow and increases heat transfer. In the second method, using nanofluids or salt and other materials increases the heat transfer of water. The use of porous materials has grown up immensely over the past twenty years. Porous materials, especially copper porous foam, are widely used in solar collectors. Due to the high contact surface area, porous media are appropriate candidates for solar collectors [8]. A number of researchers investigated Solar System performance in accordance with energy and exergy analyses. Zhai et al. [9] reviewed the performance of a small solar-powered system in which the energy efficiency was 44.7% and the electrical efficiency was 16.9%.

Abbasi et al. [10] proposed an innovative multiobjective optimization to optimize the design of a cogeneration system. Results showed the CCHP system based on an internal diesel combustion engine was the applicable alternative at all regions with different climates. The diesel engine can supply the electrical requirement of 31.0% and heating demand of 3.8% for building.

Jiang et al. [11] combined the experiment and simulation together to analyze the performance of a cogeneration system. Moreover, some research focused on CCHP systems using solar energy. It integrated sustainable and renewable technologies in the CCHP, like PV, Stirling engine, and parabolic trough collector (PTC) [2, 12–15].

Wang et al. [16] optimized a cogeneration solar cooling system with a Rankine cycle and ejector to reach the maximum total system efficiency of 55.9%. Jing et al. analyzed a big-scale building with the SCCHP system and auxiliary heaters to produced electrical, cooling, and heating power. The maximum energy efficiency reported in their work is 46.6% [17]. Various optimization methods have been used to improve the cogeneration system, minimum system size, and performance, such as genetic algorithm [18, 19].

Hirasawa et al. [20] investigated the effect of using porous media to reduce thermal waste in solar systems. They used the high-porosity metal foam on top of the flat plate solar collector and observed that thermal waste decreased by 7% due to natural heat transfer. Many researchers study the efficiency improvement of the solar collector by changing the collector’s shapes or working fluids. However, the most effective method is the use of nanofluids in the solar collector as working fluid [21]. In the experimental study done by Jouybari et al. [22], the efficiency enhancement up to 8.1% was achieved by adding nanofluid in a flat plate collector. In this research, by adding porous materials to the solar collector, collector efficiency increased up to 92% in a low flow regime. Subramani et al. [23] analyzed the thermal performance of the parabolic solar collector with Al2O3 nanofluid. They conducted their experiments with Reynolds number range 2401 to 7202 and mass flow rate 0.0083 to 0.05 kg/s. The maximum efficiency improvement in this experiment was 56% at 0.05 kg/s mass flow rate.

Shojaeizadeh et al. [24] investigated the analysis of the second law of thermodynamic on the flat plate solar collector using Al2O3/water nanofluid. Their research showed that energy efficiency rose up to 1.9% and the exergy efficiency increased by a maximum of 0.72% compared to pure water. Tiwari et al. [25] researched on the thermal performance of solar flat plate collectors for working fluid water with different nanofluids. The result showed that using 1.5% (optimum) particle volume fraction of Al2O3 nanofluid as an absorbing medium causes the thermal efficiency to enhance up to 31.64%.

The effect of porous media and nanofluids on solar collectors has already been investigated in the literature but the SCCHP system with a collector embedded by both porous media and nanofluid for enhancing the ratio of nanoparticle in nanofluid for preventing sedimentation was not discussed. In this research, the amount of energy and exergy of the solar CCHP cycles with parabolic solar collectors in both base and improved modes with a porous material (copper foam with 95% porosity) and nanofluid with different ratios of nanoparticles was calculated. In the first step, it is planned to design a CCHP system based on the required load, and, in the next step, it will analyze the energy and exergy of the system in a basic and optimize mode. In the optimize mode, enhanced solar collectors with porous material and nanofluid in different ratios (0.1%–0.7%) were used to optimize the ratio of nanofluids to prevent sedimentation.

2. Cycle Description

CCHP is one of the methods to enhance energy efficiency and reduce energy loss and costs. The SCCHP system used a solar collector as a prime mover of the cogeneration system and assisted the boiler to generate vapor for the turbine. Hot water flows from the expander to the absorption chiller in summer or to the radiator or fan coil in winter. Finally, before the hot water wants to flow back to the storage tank, it flows inside a heat exchanger for generating domestic hot water [26].

For designing of solar cogeneration system and its analysis, it is necessary to calculate the electrical, heating (heating load is the load required for the production of warm water and space heating), and cooling load required for the case study considered in a residential building with an area of 600 m2 in the warm region of Iran (Zahedan). In Table 1, the average of the required loads is shown for the different months of a year (average of electrical, heating, and cooling load calculated with CARRIER software).Table 1 The average amount of electric charges, heating load, and cooling load used in the different months of the year in the city of Zahedan for a residential building with 600 m2.

According to Table 1, the maximum magnitude of heating, cooling, and electrical loads is used to calculate the cogeneration system. The maximum electric load is 96 kW, the maximum amount of heating load is 62 kW, and the maximum cooling load is 118 kW. Since the calculated loads are average, all loads increased up to 10% for the confidence coefficient. With the obtained values, the solar collector area and other cogeneration system components are calculated. The cogeneration cycle is capable of producing 105 kW electric power, 140 kW cooling capacity, and 100 kW heating power.

2.1. System Analysis Equations

An analysis is done by considering the following assumptions:(1)The system operates under steady-state conditions(2)The system is designed for the warm region of Iran (Zahedan) with average solar radiation Ib = 820 w/m2(3)The pressure drops in heat exchangers, separators, storage tanks, and pipes are ignored(4)The pressure drop is negligible in all processes and no expectable chemical reactions occurred in the processes(5)Potential, kinetic, and chemical exergy are not considered due to their insignificance(6)Pumps have been discontinued due to insignificance throughout the process(7)All components are assumed adiabatic

Schematic shape of the cogeneration cycle is shown in Figure 1 and all data are given in Table 2.

Figure 1 Schematic shape of the cogeneration cycle.Table 2 Temperature and humidity of different points of system.

Based on the first law of thermodynamic, energy analysis is based on the following steps.

First of all, the estimated solar radiation energy on collector has been calculated:where α is the heat transfer enhancement coefficient based on porous materials added to the collector’s pipes. The coefficient α is increased by the porosity percentage, the type of porous material (in this case, copper with a porosity percentage of 95), and the flow of fluid to the collector equation.

Collector efficiency is going to be calculated by the following equation [9]:

Total energy received by the collector is given by [9]

Also, the auxiliary boiler heat load is [2]

Energy consumed from vapor to expander is calculated by [2]

The power output form by the screw expander [9]:

The efficiency of the expander is 80% in this case [11].

In this step, cooling and heating loads were calculated and then, the required heating load to reach sanitary hot water will be calculated as follows:

First step: calculating the cooling load with the following equation [9]:

Second step: calculating heating loads [9]:

Then, calculating the required loud for sanitary hot water will be [9]

According to the above-mentioned equations, efficiency is [9]

In the third step, calculated exergy analysis as follows.

First, the received exergy collector from the sun is calculated [9]:

In the previous equation, f is the constant of air dilution.

The received exergy from the collector is [9]

In the case of using natural gas in an auxiliary heater, the gas exergy is calculated from the following equation [12]:

Delivering exergy from vapor to expander is calculated with the following equation [9]:

In the fourth step, the exergy in cooling and heating is calculated by the following equation:

Cooling exergy in summer is calculated [9]:

Heating exergy in winter is calculated [9]:

In the last step based on thermodynamic second law, exergy efficiency has been calculated from the following equation and the above-mentioned calculated loads [9]:

3. Porous Media

The porous medium that filled the test section is copper foam with a porosity of 95%. The foams are determined in Figure 2 and also detailed thermophysical parameters and dimensions are shown in Table 3.

Figure 2 Copper foam with a porosity of 95%.Table 3 Thermophysical parameters and dimensions of copper foam.

In solar collectors, copper porous materials are suitable for use at low temperatures and have an easier and faster manufacturing process than ceramic porous materials. Due to the high coefficient conductivity of copper, the use of copper metallic foam to increase heat transfer is certainly more efficient in solar collectors.

Porous media and nanofluid in solar collector’s pipes were simulated in FLOW-3D software using the finite-difference method [27]. Nanoparticles Al2O3 and CUO are mostly used in solar collector enhancement. In this research, different concentrations of nanofluid are added to the parabolic solar collectors with porous materials (copper foam with porosity of 95%) to achieve maximum heat transfer in the porous materials before sedimentation. After analyzing PTC pipes with the nanofluid flow in FLOW-3D software, for energy and exergy efficiency analysis, Carrier software results were used as EES software input. Simulation PTC with porous media inside collector pipe and nanofluids sedimentation is shown in Figure 3.

Figure 3 Simulation PTC pipes enhanced with copper foam and nanoparticles in FLOW-3D software.

3.1. Nano Fluid

In this research, copper and silver nanofluids (Al2O3, CuO) have been added with percentages of 0.1%–0.7% as the working fluids. The nanoparticle properties are given in Table 4. Also, system constant parameters are presented in Table 4, which are available as default input in the EES software.Table 4 Properties of the nanoparticles [9].

System constant parameters for input in the software are shown in Table 5.Table 5 System constant parameters.

The thermal properties of the nanofluid can be obtained from equations (18)–(21). The basic fluid properties are indicated by the index (bf) and the properties of the nanoparticle silver with the index (np).

The density of the mixture is shown in the following equation [28]:where ρ is density and ϕ is the nanoparticles volume fraction.

The specific heat capacity is calculated from the following equation [29]:

The thermal conductivity of the nanofluid is calculated from the following equation [29]:

The parameter β is the ratio of the nanolayer thickness to the original particle radius and, usually, this parameter is taken equal to 0.1 for the calculated thermal conductivity of the nanofluids.

The mixture viscosity is calculated as follows [30]:

In all equations, instead of water properties, working fluids with nanofluid are used. All of the above equations and parameters are entered in the EES software for calculating the energy and exergy of solar collectors and the SCCHP cycle. All calculation repeats for both nanofluids with different concentrations of nanofluid in the solar collector’s pipe.

4. Results and Discussion

In the present study, relations were written according to Wang et al. [16] and the system analysis was performed to ensure the correctness of the code. The energy and exergy charts are plotted based on the main values of the paper and are shown in Figures 4 and 5. The error rate in this simulation is 1.07%.

Figure 5 Verification charts of exergy analysis results.

We may also investigate the application of machine learning paradigms [31–41] and various hybrid, advanced optimization approaches that are enhanced in terms of exploration and intensification [42–55], and intelligent model studies [56–61] as well, for example, methods such as particle swarm optimizer (PSO) [60, 62], differential search (DS) [63], ant colony optimizer (ACO) [61, 64, 65], Harris hawks optimizer (HHO) [66], grey wolf optimizer (GWO) [53, 67], differential evolution (DE) [68, 69], and other fusion and boosted systems [41, 46, 48, 50, 54, 55, 70, 71].

At the first step, the collector is modified with porous copper foam material. 14 cases have been considered for the analysis of the SCCHP system (Table 6). It should be noted that the adding of porous media causes an additional pressure drop inside the collector [9, 22–26, 30, 72]. All fourteen cases use copper foam with a porosity of 95 percent. To simulate the effect of porous materials and nanofluids, the first solar PTC pipes have been simulated in the FLOW-3D software and then porous media (copper foam with porosity of 95%) and fluid flow with nanoparticles (AL2O3 and CUO) are generated in the software. After analyzing PTC pipes in FLOW-3D software, for analyzing energy and exergy efficiency, software outputs were used as EES software input for optimization ratio of sedimentation and calculating energy and exergy analyses.Table 6 Collectors with different percentages of nanofluids and porous media.

In this research, an enhanced solar collector with both porous media and Nanofluid is investigated. In the present study, 0.1–0.5% CuO and Al2O3 concentration were added to the collector fully filled by porous media to achieve maximum energy and exergy efficiencies of solar CCHP systems. All steps of the investigation are shown in Table 6.

Energy and exergy analyses of parabolic solar collectors and SCCHP systems are shown in Figures 6 and 7.

Figure 6 Energy and exergy efficiencies of the PTC with porous media and nanofluid.

Figure 7 Energy and exergy efficiency of the SCCHP.

Results show that the highest energy and exergy efficiencies are 74.19% and 32.6%, respectively, that is achieved in Step 12 (parabolic collectors with filled porous media and 0.5% Al2O3). In the second step, the maximum energy efficiency of SCCHP systems with fourteen steps of simulation are shown in Figure 7.

In the second step, where 0.1, −0.6% of the nanofluids were added, it is found that 0.5% leads to the highest energy and exergy efficiency enhancement in solar collectors and SCCHP systems. Using concentrations more than 0.5% leads to sediment in the solar collector’s pipe and a decrease of porosity in the pipe [73]. According to Figure 7, maximum energy and exergy efficiencies of SCCHP are achieved in Step 12. In this step energy efficiency is 54.49% and exergy efficiency is 18.29%. In steps 13 and 14, with increasing concentration of CUO and Al2O3 nanofluid solution in porous materials, decreasing of energy and exergy efficiency of PTC and SCCHP system at the same time happened. This decrease in efficiency is due to the formation of sediment in the porous material. Calculations and simulations have shown that porous materials more than 0.5% nanofluids inside the collector pipe cause sediment and disturb the porosity of porous materials and pressure drop and reduce the coefficient of performance of the cogeneration system. Most experience showed that CUO and AL2O3 nanofluids with less than 0.6% percent solution are used in the investigation on the solar collectors at low temperatures and discharges [74]. One of the important points of this research is that the best ratio of nanofluids in the solar collector with a low temperature is 0.5% (AL2O3 and CUO); with this replacement, the cost of solar collectors and SCCHP cycle is reduced.

5. Conclusion and Future Directions

In the present study, ways for increasing the efficiency of solar collectors in order to enhance the efficiency of the SCCHP cycle are examined. The research is aimed at adding both porous materials and nanofluids for estimating the best ratio of nanofluid for enhanced solar collector and protecting sedimentation in porous media. By adding porous materials (copper foam with porosity of 95%) and 0.5% nanofluids together, high efficiency in solar parabolic collectors can be achieved. The novelty in this research is the addition of both nanofluids and porous materials and calculating the best ratio for preventing sedimentation and pressure drop in solar collector’s pipe. In this study, it was observed that, by adding 0.5% of AL2O3 nanofluid in working fluids, the energy efficiency of PTC rises to 74.19% and exergy efficiency is grown up to 32.6%. In SCCHP cycle, energy efficiency is 54.49% and exergy efficiency is 18.29%.

In this research, parabolic solar collectors fully filled by porous media (copper foam with a porosity of 95) are investigated. In the next step, parabolic solar collectors in the SCCHP cycle were simultaneously filled by porous media and different percentages of Al2O3 and CuO nanofluid. At this step, values of 0.1% to 0.6% of each nanofluid were added to the working fluid, and the efficiency of the energy and exergy of the collectors and the SCCHP cycle were determined. In this case, nanofluid and the porous media were used together in the solar collector and maximum efficiency achieved. 0.5% of both nanofluids were used to achieve the biggest efficiency enhancement.

In the present study, as expected, the highest efficiency is for the parabolic solar collector fully filled by porous material (copper foam with a porosity of 95%) and 0.5% Al2O3. Results of the present study are as follows:(1)The average enhancement of collectors’ efficiency using porous media and nanofluids is 28%.(2)Solutions with 0.1 to 0.5% of nanofluids (CuO and Al2O3) are used to prevent collectors from sediment occurrence in porous media.(3)Collector of solar cogeneration cycles that is enhanced by both porous media and nanofluid has higher efficiency, and the stability of output temperature is more as well.(4)By using 0.6% of the nanofluids in the enhanced parabolic solar collectors with copper porous materials, sedimentation occurs and makes a high-pressure drop in the solar collector’s pipe which causes decrease in energy efficiency.(5)Average enhancement of SCCHP cycle efficiency is enhanced by both porous media and nanofluid 13%.

Abstract

The low efficiency of Collectors that absorb energy can be mentioned as one of the drawbacks in solar cogeneration cycles. In the present study, solar systems have been improved by adding porous media and Nanofluid to collectors. One advantage of using porous media and nanomaterials is to absorb more energy while the surface area is reduced. In this study, first, solar collectors are enhanced using 90% porosity copper in solar combined cooling, heating and power systems (SCCHP). Second, different percentages of CuO and Al2O3 nano-fluids are added to a flat plate and parabolic collectors to enhance thermal properties. Simulations are performed in different modes (simple parabolic collectors, simple flat plate collectors, improved flat plate collectors, parabolic collectors with porous media, and flat plate and parabolic collectors with different density of CuO and Al2O3 nanofluids). A case study is investigated for warm and dry regions with mean solar radiation Ib = 820 w / m2 in Iran. The maximum energy and exergy efficiencies are 60.12% and 18.84%, respectively, that is related to enhanced parabolic solar collectors with porous media and nanofluids. Adding porous media and nano-fluids increases an average 14.4% collector energy efficiency and 8.08% collector exergy efficiency.

Forming characteristics and control method of weld bead for GMAW on curved surface

Forming characteristics and control method of weld bead for GMAW on curved surface

The International Journal of Advanced Manufacturing Technology (2021)Cite this article

Abstract

곡면에서 GMAW 기반 적층 가공의 용접 성형 특성은 중력의 영향을 크게 받습니다. 성형면의 경사각이 크면 혹 비드(hump bead)와 같은 심각한 결함이 발생합니다.

본 논문에서는 양생면에서 용접 비드 형성의 형성 특성과 제어 방법을 연구하기 위해 용접 용융 풀 유동 역학의 전산 모델을 수립하고 제안된 모델을 검증하기 위해 증착 실험을 수행하였습니다.

결과는 용접 비드 경사각(α)이 증가함에 따라 역류의 속도가 증가하고 상향 용접의 경우 α > 60°일 때 불규칙한 험프 결함이 나타나는 것으로 나타났습니다.

상부 과잉 액체의 하향 압착력과 하부 상향 유동의 반동력과 표면장력 사이의 상호작용은 용접 혹 형성의 주요 요인이었다. 하향 용접의 경우 양호한 형태를 얻을 수 있었으며, 용접 비드 경사각이 증가함에 따라 용접 높이는 감소하고 용접 폭은 증가하였습니다.

하향 및 상향 용접을 위한 곡면의 용융 거동 및 성형 특성을 기반으로 험프 결함을 제어하기 위해 위브 용접을 통한 증착 방법을 제안하였습니다.

성형 궤적의 변화로 인해 용접 방향의 중력 성분이 크게 감소하여 용융 풀 흐름의 안정성이 향상되었으며 복잡한 표면에서 안정적이고 일관된 용접 비드를 얻는 데 유리했습니다.

하향 용접과 상향 용접 사이의 단일 비드의 치수 편차는 7% 이내였으며 하향 및 상향 혼합 혼합 비드 중첩 증착에서 비드의 변동 편차는 0.45로 GMAW 기반 적층 제조 공정에서 허용될 수 있었습니다.

이러한 발견은 GMAW를 기반으로 하는 곡선 적층 적층 제조의 용접 비드 형성 제어에 기여했습니다.

The weld forming characteristics of GMAW-based additive manufacturing on curved surface are dramatically influenced by gravity. Large inclined angle of the forming surface would lead to severe defects such as hump bead. In this paper, a computational model of welding molten pool flow dynamics was established to research the forming characteristic and control method of weld bead forming on cured surface, and deposition experiments were conducted to verify the proposed model. Results indicated that the velocity of backward flows increased with the increase of weld bead tilt angle (α) and irregular hump defects appeared when α > 60° for upward welding. The interaction between the downward squeezing force of the excess liquid at the top and the recoil force of the upward flow at the bottom and the surface tension were primary factors for welding hump formation. For downward welding, a good morphology shape could be obtained, and the weld height decreased and the weld width increased with the increase of weld bead tilt angle. Based on the molten behaviors and forming characteristics on curved surface for downward and upward welding, the method of deposition with weave welding was proposed to control hump defects. Gravity component in the welding direction was significantly reduced due to the change of forming trajectory, which improved the stability of the molten pool flow and was beneficial to obtain stable and consistent weld bead on complex surface. The dimensional deviations of the single bead between downward and upward welding were within 7% and the fluctuation deviation of the bead in multi-bead overlapping deposition with mixing downward and upward welding was 0.45, which could be acceptable in GMAW-based additive manufacturing process. These findings contributed to the weld bead forming control of curve layered additive manufacturing based on GMAW.

Abstract

두 개의 부유체 사이에 간격이 있는 경사진 부유식 방파제(FB)에 대한 새로운 연구가 제안되었습니다. 구조물의 기울기는 파동 에너지 소산을 유발할 수 있습니다. 경사진 구조물의 문제는 파도가 넘친다는 것입니다. 이 문제를 해결하기 위해 두 플로터 사이의 간격을 고려합니다. 

오버 토핑이 발생하면 마루를 통과하는 물이 두 플로터 사이의 틈으로 쏟아지며 결과적으로 파도 에너지가 감쇠됩니다. 체인 네트가 모델에 추가되고 전송 계수에 대한 영향이 연구됩니다. 또한, 구조물의 유체역학적 성능에 대한 자유도의 영향을 조사하기 위해 말뚝으로 고정된(1 자유도) 계류 라인으로 고정된(3도의 자유도) 두 가지 고정 시스템에서 자유 모델을 연구했습니다.

게다가, 실험은 5개의 다른 파도 주기와 4개의 다른 파도 높이를 가진 규칙파에서 수행됩니다. 실험 결과, 경사형 부유식 방파제가 직사각형 상자형보다 최대 15% 성능이 우수한 것으로 나타났다. 말뚝에 의해 고정된 FB에 대한 투과계수는 단파에서 케이블에 의해 고정된 FB보다 최대값으로 약 14% 낮고 장파에서 약 4-10% 더 높다. 흘수가 증가함에 따라 전송 계수는 감소하지만 건현은 허용 비율의 초과를 제한하기 위한 최소 요구 사항을 충족해야 합니다. 

체인 그물이 있는 모델은 없는 모델에 비해 전달 계수가 최대 14% 감소하여 더 나은 성능을 나타냅니다. 실험 결과, 경사형 부유식 방파제가 직사각형 상자형보다 최대 15% 성능이 우수한 것으로 나타났다. 말뚝에 의해 고정된 FB에 대한 투과계수는 단파에서 케이블에 의해 고정된 FB보다 최대값으로 약 14% 낮고 장파에서 약 4-10% 더 높다. 흘수가 증가함에 따라 전송 계수는 감소하지만 건현은 허용 비율의 초과를 제한하기 위한 최소 요구 사항을 충족해야 합니다.

A novel study of sloping floating breakwater (FB) that has a gap between two floaters is proposed. The slope of a structure can cause wave energy dissipation. A problem with sloping structures is wave overtopping. To solve this problem, a gap is considered between the two floaters. If overtopping occurs, water passing the crest will pour into the gap between the two floaters, as a result wave energy will be attenuated. A chain net is added to the model and its effect on the transmission coefficient is studied. Furthermore, in order to investigate the effects of the degree of freedom on the hydrodynamic performance of the structure, the model is studied in the two anchorage systems which are anchored by pile (1 degree of freedom) and anchored by mooring lines (3 degree of freedom). Moreover, the experiments are performed under regular waves with five different wave periods and four different wave heights. The results of the experiments show a sloping floating breakwater that has a better performance than that of rectangular box type by 15% as maximum value. The transmission coefficients for the FB anchored by pile are lower about 14% as maximum value than that of the FB anchored by cable in shorter waves and are higher about 4–10% in longer waves. With increasing the draft, the transmission coefficient decreases but the freeboard should meet the minimum requirements to restrict overtopping in the allowable rate. The model with a chain net exhibits a better performance as compared with the model without it by a maximum 14% reduction in the transmission coefficients.

Comparative study of experimental and CFD analysis for predicting discharge coefficient of compound broad crested weir

ABSTRACT

Present study highlights the behavior of weir crest head and width parameter on the discharge coefficient of compound broad crested (CBC) weir. Computational fluid dynamics model (CFD) is validated with laboratory experimental investigations.

In the discharge analysis through broad crested weirs, the upstream head over the weir crest (h) is crucial, where the result is mainly dependent upon the weir crest length (L) in transverse direction to flow, water depth from channel bed. Currently, minimal investigations are known for CFD validations on compound broad crested weirs.

The hydraulic research for measuring discharge numerically is carried out using FLOW 3D software. The model applies renormalized group (RNG) using volume of fluid (VOF) method for improved accuracy in free surface simulations. Structured hexagonal meshes of cubic elements define discretized meshing.

The comparative analysis of the numerical simulations and experimental observations confirm the performance of CBC weir for precise measurement of a wide range of discharges. Series of CFD model studies and experimental validation have led to constant range of discharg coefficients for various head over weir crest. The correlation coefficient of discharge predictions is 0.999 with mean error of 0.28%.

현재 연구에서는 CBC(compound broad crested) 위어의 배출 계수에 대한 위어 볏 머리 및 너비 매개변수의 거동을 강조합니다. 전산 유체 역학 모델(CFD)은 실험실 실험 조사를 통해 검증되었습니다.

넓은 볏이 있는 둑을 통한 유출 분석에서 둑 마루의 상류 수두(h)가 중요합니다. 여기서 결과는 주로 흐름에 대한 횡 방향의 둑 마루 길이(L), 수로 바닥에서 수심에 따라 달라집니다. . 현재 복합 넓은 볏 둑에 대한 CFD 검증에 대해 최소한의 조사가 알려져 있습니다.

수압 연구는 FLOW 3D 소프트웨어를 사용하여 수치적으로 측정합니다. 이 모델은 자유 표면 시뮬레이션의 정확도 향상을 위해 VOF(유체 체적) 방법을 사용하여 RNG(재정규화 그룹)를 적용합니다. 정육면체 요소의 구조화된 육각형 메쉬는 이산화된 메쉬를 정의합니다.

수치 시뮬레이션과 실험적 관찰의 비교 분석을 통해 광범위한 배출의 정확한 측정을 위한 CBC 둑의 성능을 확인했습니다. 일련의 CFD 모델 연구와 실험적 검증을 통해 다양한 head over weir crest에 대한 일정한 범위의 방전 계수가 나타났습니다. 방전 예측의 상관 계수는 0.999이고 평균 오차는 0.28%입니다.

HIGHLIGHTS

• The Head-Discharge relation is established for discharge measurement using compound broad crested weir, experimentally and numerically.
• Assessment of head over weir crest for different step widths of proposed weir on discharge coefficient is executed.
• Experimental and CFD results of weir performance demonstrate good agreement between the theoretical discharges by traditional rectangular weir formulae keeping Cd constant.

CONCLUSION

  1. The head discharge relationship established for compound rectangular broad crested weir for various discharge ranges was validated by CFD technique. A three dimensional simulation software FLOW 3D was used for this purpose.
  2. Original theoretical compound weir model depicts the relative average error between discharge predictions with Flow 3D simulation as 4.96% which is found less than the predictions made by graphical interpolation technique which is 5.33%.
  3. The standard deviation in Cd parameter for CFD simulation model is less i.e. 0.0146 as compared to experimental output of 0.0502.
  4. The correlation coefficient for physical and CFD studies for modified compound weir model is high, around 0.999 with
    error in discharge predictions being 0.28% as compared to the accuracy limits of about +3–5% stated in literature so far.
  5. Discharge coefficient by experimental and CFD approach is maintained constant and equal to design input value of 0.6.
    Thus, the proposed CBC weir can be operated for various discharge ranges by maintaining constant discharge coefficients.
    Good agreement between the theoretical, experimental and CFD simulation results for obtaining discharge through compound broad crested weir ascertains the fact that CFD model can be used as an effective tool towards modeling flow through compound broad crested weir.

Shock Waves in Spillway Chute

W.C. Bennett 댐에서는 1960년대 물리적 유압 모델과 프로토 타입 사이에 있었던 레일 궤도의 차이로 인해 충격파 형성에 대한 신뢰할 수 있는 결론을 도출하기 어렵습니다. 이 자료는 실제 모델 테스트 결과의 슈트 용량을 제공합니다. 콘크리트 라인 스풀 레이 슈트의 충격 파장의 크기는 헤드 워크에 있는 세 개의 방사형 게이트의 다운 스트림이 44% 감소되는데 크게 영향을 받습니다. 방사형 관문의 방사형 개구부의 충격파는 지역적으로 더 높은 수위로 이어져 특정 과거 작업에서 슈트 월의 과다 주입을 야기합니다.

2012년에 최대 2,865 m3/s 의 배출에 대한 프로토 타입 유출 테스트가 실행되어 슈트 벽, 슈트 내 물 표면에 대한 3D레이저 스캔 및 FLOW-3D model 보정을 위한 흐름 패턴. 수치 모델과 현장 관찰 간에, 특히 슈트 월의 첫번째 충격파의 위치와 높이 사이에 훌륭한 일치가 이루어졌습니다.

Abstract

Vegetation along the river increases the roughness and reduces the average flow velocity, reduces flow energy, and changes the flow velocity profile in the cross section of the river. Many canals and rivers in nature are covered with vegetation during the floods. Canal’s roughness is strongly affected by plants and therefore it has a great effect on flow resistance during flood. Roughness resistance against the flow due to the plants depends on the flow conditions and plant, so the model should simulate the current velocity by considering the effects of velocity, depth of flow, and type of vegetation along the canal. Total of 48 models have been simulated to investigate the effect of roughness in the canal. The results indicated that, by enhancing the velocity, the effect of vegetation in decreasing the bed velocity is negligible, while when the current has lower speed, the effect of vegetation on decreasing the bed velocity is obviously considerable.


강의 식생은 거칠기를 증가시키고 평균 유속을 감소시키며, 유속 에너지를 감소시키고 강의 단면에서 유속 프로파일을 변경합니다. 자연의 많은 운하와 강은 홍수 동안 초목으로 덮여 있습니다. 운하의 조도는 식물의 영향을 많이 받으므로 홍수시 유동저항에 큰 영향을 미칩니다. 식물로 인한 흐름에 대한 거칠기 저항은 흐름 조건 및 식물에 따라 다르므로 모델은 유속, 흐름 깊이 및 운하를 따라 식생 유형의 영향을 고려하여 현재 속도를 시뮬레이션해야 합니다. 근관의 거칠기의 영향을 조사하기 위해 총 48개의 모델이 시뮬레이션되었습니다. 결과는 유속을 높임으로써 유속을 감소시키는 식생의 영향은 무시할 수 있는 반면, 해류가 더 낮은 유속일 때 유속을 감소시키는 식생의 영향은 분명히 상당함을 나타냈다.

1. Introduction

Considering the impact of each variable is a very popular field within the analytical and statistical methods and intelligent systems [1–14]. This can help research for better modeling considering the relation of variables or interaction of them toward reaching a better condition for the objective function in control and engineering [15–27]. Consequently, it is necessary to study the effects of the passive factors on the active domain [28–36]. Because of the effect of vegetation on reducing the discharge capacity of rivers [37], pruning plants was necessary to improve the condition of rivers. One of the important effects of vegetation in river protection is the action of roots, which cause soil consolidation and soil structure improvement and, by enhancing the shear strength of soil, increase the resistance of canal walls against the erosive force of water. The outer limbs of the plant increase the roughness of the canal walls and reduce the flow velocity and deplete the flow energy in vicinity of the walls. Vegetation by reducing the shear stress of the canal bed reduces flood discharge and sedimentation in the intervals between vegetation and increases the stability of the walls [38–41].

One of the main factors influencing the speed, depth, and extent of flood in this method is Manning’s roughness coefficient. On the other hand, soil cover [42], especially vegetation, is one of the most determining factors in Manning’s roughness coefficient. Therefore, it is expected that those seasonal changes in the vegetation of the region will play an important role in the calculated value of Manning’s roughness coefficient and ultimately in predicting the flood wave behavior [43–45]. The roughness caused by plants’ resistance to flood current depends on the flow and plant conditions. Flow conditions include depth and velocity of the plant, and plant conditions include plant type, hardness or flexibility, dimensions, density, and shape of the plant [46]. In general, the issue discussed in this research is the optimization of flood-induced flow in canals by considering the effect of vegetation-induced roughness. Therefore, the effect of plants on the roughness coefficient and canal transmission coefficient and in consequence the flow depth should be evaluated [47, 48].

Current resistance is generally known by its roughness coefficient. The equation that is mainly used in this field is Manning equation. The ratio of shear velocity to average current velocity  is another form of current resistance. The reason for using the  ratio is that it is dimensionless and has a strong theoretical basis. The reason for using Manning roughness coefficient is its pervasiveness. According to Freeman et al. [49], the Manning roughness coefficient for plants was calculated according to the Kouwen and Unny [50] method for incremental resistance. This method involves increasing the roughness for various surface and plant irregularities. Manning’s roughness coefficient has all the factors affecting the resistance of the canal. Therefore, the appropriate way to more accurately estimate this coefficient is to know the factors affecting this coefficient [51].

To calculate the flow rate, velocity, and depth of flow in canals as well as flood and sediment estimation, it is important to evaluate the flow resistance. To determine the flow resistance in open ducts, Manning, Chézy, and Darcy–Weisbach relations are used [52]. In these relations, there are parameters such as Manning’s roughness coefficient (n), Chézy roughness coefficient (C), and Darcy–Weisbach coefficient (f). All three of these coefficients are a kind of flow resistance coefficient that is widely used in the equations governing flow in rivers [53].

The three relations that express the relationship between the average flow velocity (V) and the resistance and geometric and hydraulic coefficients of the canal are as follows:where n, f, and c are Manning, Darcy–Weisbach, and Chézy coefficients, respectively. V = average flow velocity, R = hydraulic radius, Sf = slope of energy line, which in uniform flow is equal to the slope of the canal bed,  = gravitational acceleration, and Kn is a coefficient whose value is equal to 1 in the SI system and 1.486 in the English system. The coefficients of resistance in equations (1) to (3) are related as follows:

Based on the boundary layer theory, the flow resistance for rough substrates is determined from the following general relation:where f = Darcy–Weisbach coefficient of friction, y = flow depth, Ks = bed roughness size, and A = constant coefficient.

On the other hand, the relationship between the Darcy–Weisbach coefficient of friction and the shear velocity of the flow is as follows:

By using equation (6), equation (5) is converted as follows:

Investigation on the effect of vegetation arrangement on shear velocity of flow in laboratory conditions showed that, with increasing the shear Reynolds number (), the numerical value of the  ratio also increases; in other words the amount of roughness coefficient increases with a slight difference in the cases without vegetation, checkered arrangement, and cross arrangement, respectively [54].

Roughness in river vegetation is simulated in mathematical models with a variable floor slope flume by different densities and discharges. The vegetation considered submerged in the bed of the flume. Results showed that, with increasing vegetation density, canal roughness and flow shear speed increase and with increasing flow rate and depth, Manning’s roughness coefficient decreases. Factors affecting the roughness caused by vegetation include the effect of plant density and arrangement on flow resistance, the effect of flow velocity on flow resistance, and the effect of depth [45, 55].

One of the works that has been done on the effect of vegetation on the roughness coefficient is Darby [56] study, which investigates a flood wave model that considers all the effects of vegetation on the roughness coefficient. There are currently two methods for estimating vegetation roughness. One method is to add the thrust force effect to Manning’s equation [47, 57, 58] and the other method is to increase the canal bed roughness (Manning-Strickler coefficient) [45, 59–61]. These two methods provide acceptable results in models designed to simulate floodplain flow. Wang et al. [62] simulate the floodplain with submerged vegetation using these two methods and to increase the accuracy of the results, they suggested using the effective height of the plant under running water instead of using the actual height of the plant. Freeman et al. [49] provided equations for determining the coefficient of vegetation roughness under different conditions. Lee et al. [63] proposed a method for calculating the Manning coefficient using the flow velocity ratio at different depths. Much research has been done on the Manning roughness coefficient in rivers, and researchers [49, 63–66] sought to obtain a specific number for n to use in river engineering. However, since the depth and geometric conditions of rivers are completely variable in different places, the values of Manning roughness coefficient have changed subsequently, and it has not been possible to choose a fixed number. In river engineering software, the Manning roughness coefficient is determined only for specific and constant conditions or normal flow. Lee et al. [63] stated that seasonal conditions, density, and type of vegetation should also be considered. Hydraulic roughness and Manning roughness coefficient n of the plant were obtained by estimating the total Manning roughness coefficient from the matching of the measured water surface curve and water surface height. The following equation is used for the flow surface curve:where  is the depth of water change, S0 is the slope of the canal floor, Sf is the slope of the energy line, and Fr is the Froude number which is obtained from the following equation:where D is the characteristic length of the canal. Flood flow velocity is one of the important parameters of flood waves, which is very important in calculating the water level profile and energy consumption. In the cases where there are many limitations for researchers due to the wide range of experimental dimensions and the variety of design parameters, the use of numerical methods that are able to estimate the rest of the unknown results with acceptable accuracy is economically justified.

FLOW-3D software uses Finite Difference Method (FDM) for numerical solution of two-dimensional and three-dimensional flow. This software is dedicated to computational fluid dynamics (CFD) and is provided by Flow Science [67]. The flow is divided into networks with tubular cells. For each cell there are values of dependent variables and all variables are calculated in the center of the cell, except for the velocity, which is calculated at the center of the cell. In this software, two numerical techniques have been used for geometric simulation, FAVOR™ (Fractional-Area-Volume-Obstacle-Representation) and the VOF (Volume-of-Fluid) method. The equations used at this model for this research include the principle of mass survival and the magnitude of motion as follows. The fluid motion equations in three dimensions, including the Navier–Stokes equations with some additional terms, are as follows:where  are mass accelerations in the directions x, y, z and  are viscosity accelerations in the directions x, y, z and are obtained from the following equations:

Shear stresses  in equation (11) are obtained from the following equations:

The standard model is used for high Reynolds currents, but in this model, RNG theory allows the analytical differential formula to be used for the effective viscosity that occurs at low Reynolds numbers. Therefore, the RNG model can be used for low and high Reynolds currents.

Weather changes are high and this affects many factors continuously. The presence of vegetation in any area reduces the velocity of surface flows and prevents soil erosion, so vegetation will have a significant impact on reducing destructive floods. One of the methods of erosion protection in floodplain watersheds is the use of biological methods. The presence of vegetation in watersheds reduces the flow rate during floods and prevents soil erosion. The external organs of plants increase the roughness and decrease the velocity of water flow and thus reduce its shear stress energy. One of the important factors with which the hydraulic resistance of plants is expressed is the roughness coefficient. Measuring the roughness coefficient of plants and investigating their effect on reducing velocity and shear stress of flow is of special importance.

Roughness coefficients in canals are affected by two main factors, namely, flow conditions and vegetation characteristics [68]. So far, much research has been done on the effect of the roughness factor created by vegetation, but the issue of plant density has received less attention. For this purpose, this study was conducted to investigate the effect of vegetation density on flow velocity changes.

In a study conducted using a software model on three density modes in the submerged state effect on flow velocity changes in 48 different modes was investigated (Table 1).Table 1 The studied models.

The number of cells used in this simulation is equal to 1955888 cells. The boundary conditions were introduced to the model as a constant speed and depth (Figure 1). At the output boundary, due to the presence of supercritical current, no parameter for the current is considered. Absolute roughness for floors and walls was introduced to the model (Figure 1). In this case, the flow was assumed to be nonviscous and air entry into the flow was not considered. After  seconds, this model reached a convergence accuracy of .

Figure 1 The simulated model and its boundary conditions.

Due to the fact that it is not possible to model the vegetation in FLOW-3D software, in this research, the vegetation of small soft plants was studied so that Manning’s coefficients can be entered into the canal bed in the form of roughness coefficients obtained from the studies of Chow [69] in similar conditions. In practice, in such modeling, the effect of plant height is eliminated due to the small height of herbaceous plants, and modeling can provide relatively acceptable results in these conditions.

48 models with input velocities proportional to the height of the regular semihexagonal canal were considered to create supercritical conditions. Manning coefficients were applied based on Chow [69] studies in order to control the canal bed. Speed profiles were drawn and discussed.

Any control and simulation system has some inputs that we should determine to test any technology [70–77]. Determination and true implementation of such parameters is one of the key steps of any simulation [23, 78–81] and computing procedure [82–86]. The input current is created by applying the flow rate through the VFR (Volume Flow Rate) option and the output flow is considered Output and for other borders the Symmetry option is considered.

Simulation of the models and checking their action and responses and observing how a process behaves is one of the accepted methods in engineering and science [87, 88]. For verification of FLOW-3D software, the results of computer simulations are compared with laboratory measurements and according to the values of computational error, convergence error, and the time required for convergence, the most appropriate option for real-time simulation is selected (Figures 2 and 3 ).

Figure 2 Modeling the plant with cylindrical tubes at the bottom of the canal.

Figure 3 Velocity profiles in positions 2 and 5.

The canal is 7 meters long, 0.5 meters wide, and 0.8 meters deep. This test was used to validate the application of the software to predict the flow rate parameters. In this experiment, instead of using the plant, cylindrical pipes were used in the bottom of the canal.

The conditions of this modeling are similar to the laboratory conditions and the boundary conditions used in the laboratory were used for numerical modeling. The critical flow enters the simulation model from the upstream boundary, so in the upstream boundary conditions, critical velocity and depth are considered. The flow at the downstream boundary is supercritical, so no parameters are applied to the downstream boundary.

The software well predicts the process of changing the speed profile in the open canal along with the considered obstacles. The error in the calculated speed values can be due to the complexity of the flow and the interaction of the turbulence caused by the roughness of the floor with the turbulence caused by the three-dimensional cycles in the hydraulic jump. As a result, the software is able to predict the speed distribution in open canals.

To investigate the effects of roughness with flow velocity, the trend of flow velocity changes at different depths and with supercritical flow to a Froude number proportional to the depth of the section has been obtained.

According to the velocity profiles of Figure 5, it can be seen that, with the increasing of Manning’s coefficient, the canal bed speed decreases.

According to Figures 5 to 8, it can be found that, with increasing the Manning’s coefficient, the canal bed speed decreases. But this deceleration is more noticeable than the deceleration of the models 1 to 12, which can be justified by increasing the speed and of course increasing the Froude number.

According to Figure 10, we see that, with increasing Manning’s coefficient, the canal bed speed decreases.

According to Figure 11, we see that, with increasing Manning’s coefficient, the canal bed speed decreases. But this deceleration is more noticeable than the deceleration of Figures 5–10, which can be justified by increasing the speed and, of course, increasing the Froude number.

With increasing Manning’s coefficient, the canal bed speed decreases (Figure 12). But this deceleration is more noticeable than the deceleration of the higher models (Figures 5–8 and 10, 11), which can be justified by increasing the speed and, of course, increasing the Froude number.

According to Figure 13, with increasing Manning’s coefficient, the canal bed speed decreases. But this deceleration is more noticeable than the deceleration of Figures 5 to 12, which can be justified by increasing the speed and, of course, increasing the Froude number.

According to Figure 15, with increasing Manning’s coefficient, the canal bed speed decreases.

Figure 15 Canal diagram with a depth of 3 meters and a flow rate of 5 meters per second.

According to Figure 16, with increasing Manning’s coefficient, the canal bed speed decreases. But this deceleration is more noticeable than the deceleration of the higher model, which can be justified by increasing the speed and, of course, increasing the Froude number.

Figure 16 Canal diagram with a depth of 3 meters and a flow rate of 5.1 meters per second.

According to Figure 17, it is clear that, with increasing Manning’s coefficient, the canal bed speed decreases. But this deceleration is more noticeable than the deceleration of the higher models, which can be justified by increasing the speed and, of course, increasing the Froude number.

Figure 17 Canal diagram with a depth of 3 meters and a flow rate of 5.2 meters per second.

According to Figure 18, with increasing Manning’s coefficient, the canal bed speed decreases. But this deceleration is more noticeable than the deceleration of the higher models, which can be justified by increasing the speed and, of course, increasing the Froude number.

Figure 18 Canal diagram with a depth of 3 meters and a flow rate of 5.3 meters per second.

According to Figure 19, it can be seen that the vegetation placed in front of the flow input velocity has negligible effect on the reduction of velocity, which of course can be justified due to the flexibility of the vegetation. The only unusual thing is the unexpected decrease in floor speed of 3 m/s compared to higher speeds.(a)

According to Figure 20, by increasing the speed of vegetation, the effect of vegetation on reducing the flow rate becomes more noticeable. And the role of input current does not have much effect in reducing speed.(a)

According to Figure 21, it can be seen that, with increasing speed, the effect of vegetation on reducing the bed flow rate becomes more noticeable and the role of the input current does not have much effect. In general, it can be seen that, by increasing the speed of the input current, the slope of the profiles increases from the bed to the water surface and due to the fact that, in software, the roughness coefficient applies to the channel floor only in the boundary conditions, this can be perfectly justified. Of course, it can be noted that, due to the flexible conditions of the vegetation of the bed, this modeling can show acceptable results for such grasses in the canal floor. In the next directions, we may try application of swarm-based optimization methods for modeling and finding the most effective factors in this research [2, 7, 8, 15, 18, 89–94]. In future, we can also apply the simulation logic and software of this research for other domains such as power engineering [95–99].(a)

3. Conclusion

The effects of vegetation on the flood canal were investigated by numerical modeling with FLOW-3D software. After analyzing the results, the following conclusions were reached:(i)Increasing the density of vegetation reduces the velocity of the canal floor but has no effect on the velocity of the canal surface.(ii)Increasing the Froude number is directly related to increasing the speed of the canal floor.(iii)In the canal with a depth of one meter, a sudden increase in speed can be observed from the lowest speed and higher speed, which is justified by the sudden increase in Froude number.(iv)As the inlet flow rate increases, the slope of the profiles from the bed to the water surface increases.(v)By reducing the Froude number, the effect of vegetation on reducing the flow bed rate becomes more noticeable. And the input velocity in reducing the velocity of the canal floor does not have much effect.(vi)At a flow rate between 3 and 3.3 meters per second due to the shallow depth of the canal and the higher landing number a more critical area is observed in which the flow bed velocity in this area is between 2.86 and 3.1 m/s.(vii)Due to the critical flow velocity and the slight effect of the roughness of the horseshoe vortex floor, it is not visible and is only partially observed in models 1-2-3 and 21.(viii)As the flow rate increases, the effect of vegetation on the rate of bed reduction decreases.(ix)In conditions where less current intensity is passing, vegetation has a greater effect on reducing current intensity and energy consumption increases.(x)In the case of using the flow rate of 0.8 cubic meters per second, the velocity distribution and flow regime show about 20% more energy consumption than in the case of using the flow rate of 1.3 cubic meters per second.

Performance assessment of OpenFOAM and FLOW-3D in the numerical modeling of a low Reynolds number hydraulic jump

낮은 레이놀즈 수 유압 점프의 수치 모델링에서 OpenFOAM 및 FLOW-3D의 성능 평가

Abstract

A comparative performance analysis of the CFD platforms OpenFOAM and FLOW-3D is presented, focusing on a 3D swirling turbulent flow: a steady hydraulic jump at low Reynolds number. Turbulence is treated using RANS approach RNG k-ε. A Volume Of Fluid (VOF) method is used to track the air–water interface, consequently aeration is modeled using an Eulerian–Eulerian approach. Structured meshes of cubic elements are used to discretize the channel geometry. The numerical model accuracy is assessed comparing representative hydraulic jump variables (sequent depth ratio, roller length, mean velocity profiles, velocity decay or free surface profile) to experimental data. The model results are also compared to previous studies to broaden the result validation. Both codes reproduced the phenomenon under study concurring with experimental data, although special care must be taken when swirling flows occur. Both models can be used to reproduce the hydraulic performance of energy dissipation structures at low Reynolds numbers.

CFD 플랫폼 OpenFOAM 및 FLOW-3D의 비교 성능 분석이 3D 소용돌이치는 난류인 낮은 레이놀즈 수에서 안정적인 유압 점프에 초점을 맞춰 제시됩니다. 난류는 RANS 접근법 RNG k-ε을 사용하여 처리됩니다.

VOF(Volume Of Fluid) 방법은 공기-물 계면을 추적하는 데 사용되며 결과적으로 Eulerian-Eulerian 접근 방식을 사용하여 폭기가 모델링됩니다. 입방체 요소의 구조화된 메쉬는 채널 형상을 이산화하는 데 사용됩니다. 수치 모델 정확도는 대표적인 유압 점프 변수(연속 깊이 비율, 롤러 길이, 평균 속도 프로파일, 속도 감쇠 또는 자유 표면 프로파일)를 실험 데이터와 비교하여 평가됩니다.

모델 결과는 또한 결과 검증을 확장하기 위해 이전 연구와 비교됩니다. 소용돌이 흐름이 발생할 때 특별한 주의가 필요하지만 두 코드 모두 실험 데이터와 일치하는 연구 중인 현상을 재현했습니다. 두 모델 모두 낮은 레이놀즈 수에서 에너지 소산 구조의 수리 성능을 재현하는 데 사용할 수 있습니다.

Abstract

The optimal spillway design is of great significance since these structures can reduce erosion downstream of the dams. This study proposes a risk-based optimization framework for a stepped spillway to achieve an economical design scenario with the minimum loss in hydraulic performance. Accordingly, the stepped spillway was simulated in the FLOW-3D® model, and the validated model was repeatedly performed for various geometric states.

The results were used to form a Multilayer Perceptron artificial neural network (MLP-ANN) surrogate model. Then, a risk-based optimization model was formed by coupling the MLP-ANN and NSGA-II. The concept of conditional value at risk (CVaR) was utilized to reduce the risk of the designed spillway malfunctions in high flood flow rates, while minimizing the construction cost and the loss in hydraulic performance.

Lastly, given the conflicting objectives of stakeholders, the non-cooperative graph model for conflict resolution (GMCR) was applied to achieve a compromise on the Pareto optimal solutions. Applicability of the suggested approach in the Jarreh Dam, Iran, resulted in a practical design scenario, which simultaneously minimizes the loss in hydraulic performance and the project cost and satisfies the priorities of decision-makers.

Abstract

Electromagnetic metal casting (EMC) is a casting technique that uses electromagnetic energy to heat metal powders. It is a faster, cleaner, and less time-consuming operation. Solid metals create issues in electromagnetics since they reflect the electromagnetic radiation rather than consume it—electromagnetic energy processing results in sounded pieces with higher-ranking material properties and a more excellent microstructure solution. For the physical production of the electromagnetic casting process, knowledge of electromagnetic material interaction is critical. Even where the heated material is an excellent electromagnetic absorber, the total heating quality is sometimes insufficient. Numerical modelling works on finding the proper coupled effects between properties to bring out the most effective operation. The main parameters influencing the quality of output of the EMC process are: power dissipated per unit volume into the material, penetration depth of electromagnetics, complex magnetic permeability and complex dielectric permittivity. The contact mechanism and interference pattern also, in turn, determines the quality of the process. Only a few parameters, such as the environment’s temperature, the interference pattern, and the rate of metal solidification, can be controlled by AI models. Neural networks are used to achieve exact outcomes by stimulating the neurons in the human brain. Additive manufacturing (AM) is used to design mold and cores for metal casting. The models outperformed the traditional DFA optimization approach, which is susceptible to local minima. The system works only offline, so real-time analysis and corrections are not yet possible.

전자기 금속 주조 (EMC)는 전자기 에너지를 사용하여 금속 분말을 가열하는 주조 기술입니다. 더 빠르고 깨끗하며 시간이 덜 소요되는 작업입니다.

고체 금속은 전자기 복사를 소비하는 대신 반사하기 때문에 전자기학에서 문제를 일으킵니다. 전자기 에너지 처리는 더 높은 등급의 재료 특성과 더 우수한 미세 구조 솔루션을 가진 사운드 조각을 만듭니다.

전자기 주조 공정의 물리적 생산을 위해서는 전자기 물질 상호 작용에 대한 지식이 중요합니다. 가열된 물질이 우수한 전자기 흡수재인 경우에도 전체 가열 품질이 때때로 불충분합니다. 수치 모델링은 가장 효과적인 작업을 이끌어 내기 위해 속성 간의 적절한 결합 효과를 찾는데 사용됩니다.

EMC 공정의 출력 품질에 영향을 미치는 주요 매개 변수는 단위 부피당 재료로 분산되는 전력, 전자기의 침투 깊이, 복합 자기 투과성 및 복합 유전율입니다. 접촉 메커니즘과 간섭 패턴 또한 공정의 품질을 결정합니다. 환경 온도, 간섭 패턴 및 금속 응고 속도와 같은 몇 가지 매개 변수 만 AI 모델로 제어 할 수 있습니다.

신경망은 인간 뇌의 뉴런을 자극하여 정확한 결과를 얻기 위해 사용됩니다. 적층 제조 (AM)는 금속 주조용 몰드 및 코어를 설계하는 데 사용됩니다. 모델은 로컬 최소값에 영향을 받기 쉬운 기존 DFA 최적화 접근 방식을 능가했습니다. 이 시스템은 오프라인에서만 작동하므로 실시간 분석 및 수정은 아직 불가능합니다.

ABSTRACT

Surface roughness of laser powder bed fusion (L-PBF) printed overhang regions is a major contributor to deteriorated shape accuracy/surface quality. This study investigates the mechanisms behind the evolution of surface roughness (Ra) in overhang regions. The evolution of surface morphology is the result of a combination of border track contour, powder adhesion, warp deformation, and dross formation, which is strongly related to the overhang angle (θ). When 0° ≤ θ ≤ 15°, the overhang angle does not affect Ra significantly since only a small area of the melt pool boundaries contacts the powder bed resulting in slight powder adhesion. When 15° < θ ≤ 50°, powder adhesion is enhanced by the melt pool sinking and the increased contact area between the melt pool boundary and powder bed. When θ > 50°, large waviness of the overhang contour, adhesion of powder clusters, severe warp deformation and dross formation increase Ra sharply.

레이저 파우더 베드 퓨전 (L-PBF) 프린팅 오버행 영역의 표면 거칠기는 형상 정확도 / 표면 품질 저하의 주요 원인입니다. 이 연구 는 오버행 영역에서 표면 거칠기 (Ra ) 의 진화 뒤에 있는 메커니즘을 조사합니다 . 표면 형태의 진화는 오버행 각도 ( θ ) 와 밀접한 관련이있는 경계 트랙 윤곽, 분말 접착, 뒤틀림 변형 및 드로스 형성의 조합의 결과입니다 . 0° ≤  θ  ≤ 15° 인 경우 , 용융풀 경계의 작은 영역 만 분말 베드와 접촉하여 약간의 분말 접착이 발생하기 때문에 오버행 각도가 R a에 큰 영향을 주지 않습니다 . 15° < θ 일 때  ≤ 50°, 용융 풀 싱킹 및 용융 풀 경계와 분말 베드 사이의 증가된 접촉 면적으로 분말 접착력이 향상됩니다. θ  > 50° 일 때 오버행 윤곽의 큰 파형, 분말 클러스터의 접착, 심한 휨 변형 및 드 로스 형성이 Ra 급격히 증가 합니다.

1. Introduction

레이저 분말 베드 융합 (L-PBF)은 첨단 적층 제조 (AM) 기술로, 집중된 레이저 빔을 사용하여 금속 분말을 선택적으로 융합하여 슬라이스 된 3D 컴퓨터 지원에 따라 층별로 3 차원 (3D) 금속 부품을 구축합니다. 설계 (CAD) 모델 (Chatham, Long 및 Williams 2019 ; Tan, Zhu 및 Zhou 2020 ). 재료가 인쇄 층 아래에 ​​존재하는지 여부에 따라 인쇄 영역은 각각 솔리드 영역 또는 돌출 영역으로 분류 될 수 있습니다. 따라서 오버행 영역은 고체 기판이 아니라 분말 베드 바로 위에 건설되는 특수 구조입니다 (Patterson, Messimer 및 Farrington 2017). 오버행 영역은지지 구조를 포함하거나 포함하지 않고 구축 할 수 있으며, 지지대가있는 돌출 영역의 L-PBF는 지지체가 더 낮은 밀도로 구축된다는 점을 제외 하고 (Wang and Chou 2018 ) 고체 기판의 공정과 유사합니다 (따라서 기계적 강도가 낮기 때문에 L-PBF 공정 후 기계적으로 쉽게 제거 할 수 있습니다. 따라서지지 구조로 인쇄 된 오버행 영역은 L-PBF 공정 후 지지물 제거, 연삭 및 연마와 같은 추가 후 처리 단계가 필요합니다.

수평 내부 채널의 제작과 같은 일부 특정 경우에는 공정 후 지지대를 제거하기가 어려우므로 채널 상단 절반의 돌출부 영역을 지지대없이 건설해야합니다 (Hopkinson and Dickens 2000 ). 수평 내부 채널에 사용할 수없는지지 구조 외에도 내부 표면, 특히 등각 냉각 채널 (Feng, Kamat 및 Pei 2021 ) 에서 발생하는 복잡한 3D 채널 네트워크의 경우 표면 마감 프로세스를 구현하는 것도 어렵습니다 . 결과적으로 오버행 영역은 (i) 잔류 응력에 의한 변형, (ii) 계단 효과 (Kuo et al. 2020 ; Li et al. 2020 )로 인해 설계된 모양에서 벗어날 수 있습니다 .) 및 (iii) 원하지 않는 분말 소결로 인한 향상된 표면 거칠기; 여기서, 앞의 두 요소는 일반적으로 mm 길이 스케일에서 ‘매크로’편차로 분류되고 후자는 일반적으로 µm 길이 스케일에서 ‘마이크로’편차로 인식됩니다.

열 응력에 의한 변형은 오버행 영역에서 발생하는 중요한 문제입니다 (Patterson, Messimer 및 Farrington 2017 ). 국부적 인 용융 / 냉각은 용융 풀 내부 및 주변에서 큰 온도 구배를 유도하여 응고 된 층에 집중적 인 열 응력을 유발합니다. 열 응력에 의한 뒤틀림은 고체 영역을 현저하게 변형하지 않습니다. 이러한 영역은 아래의 여러 레이어에 의해 제한되기 때문입니다. 반면에 오버행 영역은 구속되지 않고 공정 중 응력 완화로 인해 상당한 변형이 발생합니다 (Kamat 및 Pei 2019 ). 더욱이 용융 깊이는 레이어 두께보다 큽니다 (이전 레이어도 재용 해되어 빌드 된 레이어간에 충분한 결합을 보장하기 때문입니다 [Yadroitsev et al. 2013 ; Kamath et al.2014 ]),응고 된 두께가 설계된 두께보다 크기 때문에형태 편차 (예 : 드 로스 [Charles et al. 2020 ; Feng et al. 2020 ])가 발생합니다. 마이크로 스케일에서 인쇄 된 표면 (R a 및 S a ∼ 10 μm)은 기계적으로 가공 된 표면보다 거칠다 (Duval-Chaneac et al. 2018 ; Wen et al. 2018 ). 이 문제는고형화 된 용융 풀의 가장자리에 부착 된 용융되지 않은 분말의 결과로 표면 거칠기 (R a )가 일반적으로 약 20 μm인 오버행 영역에서 특히 심각합니다 (Mazur et al. 2016 ; Pakkanen et al. 2016 ).

오버행 각도 ( θ , 빌드 방향과 관련하여 측정)는 오버행 영역의 뒤틀림 편향과 표면 거칠기에 영향을 미치는 중요한 매개 변수입니다 (Kamat and Pei 2019 ; Mingear et al. 2019 ). θ ∼ 45 ° 의 오버행 각도 는 일반적으로지지 구조없이 오버행 영역을 인쇄 할 수있는 임계 값으로 합의됩니다 (Pakkanen et al. 2016 ; Kadirgama et al. 2018 ). θ 일 때이 임계 값보다 크면 오버행 영역을 허용 가능한 표면 품질로 인쇄 할 수 없습니다. 오버행 각도 외에도 레이저 매개 변수 (레이저 에너지 밀도와 관련된)는 용융 풀의 모양 / 크기 및 용융 풀 역학에 영향을줌으로써 오버행 영역의 표면 거칠기에 영향을줍니다 (Wang et al. 2013 ; Mingear et al . 2019 ).

용융 풀 역학은 고체 (Shrestha 및 Chou 2018 ) 및 오버행 (Le et al. 2020 ) 영역 모두에서 수행되는 L-PBF 공정을 포함한 레이저 재료 가공의 일반적인 물리적 현상입니다 . 용융 풀 모양, 크기 및 냉각 속도는 잔류 응력으로 인한 변형과 ​​표면 거칠기에 모두 영향을 미치므로 처리 매개 변수와 표면 형태 / 품질 사이의 다리 역할을하며 용융 풀을 이해하기 위해 수치 시뮬레이션을 사용하여 추가 조사를 수행 할 수 있습니다. 거동과 표면 거칠기에 미치는 영향. 현재까지 고체 영역의 L-PBF 동안 용융 풀 동작을 시뮬레이션하기 위해 여러 연구가 수행되었습니다. 유한 요소 방법 (FEM)과 같은 시뮬레이션 기술 (Roberts et al. 2009 ; Du et al.2019 ), 유한 차분 법 (FDM) (Wu et al. 2018 ), 전산 유체 역학 (CFD) (Lee and Zhang 2016 ), 임의의 Lagrangian-Eulerian 방법 (ALE) (Khairallah and Anderson 2014 )을 사용하여 증발 반동 압력 (Hu et al. 2018 ) 및 Marangoni 대류 (Zhang et al. 2018 ) 현상을포함하는 열 전달 (온도 장) 및 물질 전달 (용융 흐름) 프로세스. 또한 이산 요소법 (DEM)을 사용하여 무작위 분산 분말 베드를 생성했습니다 (Lee and Zhang 2016 ; Wu et al. 2018 ). 이 모델은 분말 규모의 L-PBF 공정을 시뮬레이션했습니다 (Khairallah et al. 2016) 메조 스케일 (Khairallah 및 Anderson 2014 ), 단일 트랙 (Leitz et al. 2017 )에서 다중 트랙 (Foroozmehr et al. 2016 ) 및 다중 레이어 (Huang, Khamesee 및 Toyserkani 2019 )로.

그러나 결과적인 표면 거칠기를 결정하는 오버행 영역의 용융 풀 역학은 문헌에서 거의 관심을받지 못했습니다. 솔리드 영역의 L-PBF에 대한 기존 시뮬레이션 모델이 어느 정도 참조가 될 수 있지만 오버행 영역과 솔리드 영역 간의 용융 풀 역학에는 상당한 차이가 있습니다. 오버행 영역에서 용융 금속은 분말 입자 사이의 틈새로 아래로 흘러 용융 풀이 다공성 분말 베드가 제공하는 약한 지지체 아래로 가라 앉습니다. 이것은 중력과 표면 장력의 영향이 용융 풀의 결과적인 모양 / 크기를 결정하는 데 중요하며, 결과적으로 오버행 영역의 마이크로 스케일 형태의 진화에 중요합니다. 또한 분말 입자 사이의 공극, 열 조건 (예 : 에너지 흡수,2019 ; Karimi et al. 2020 ; 노래와 영 2020 ). 표면 거칠기는 (마이크로) 형상 편차를 증가시킬뿐만 아니라 주기적 하중 동안 미세 균열의 시작 지점 역할을함으로써 기계적 강도를 저하시킵니다 (Günther et al. 2018 ). 오버행 영역의 높은 표면 거칠기는 (마이크로) 정확도 / 품질에 대한 엄격한 요구 사항이있는 부품 제조에서 L-PBF의 적용을 제한합니다.

본 연구는 실험 및 시뮬레이션 연구를 사용하여 오버행 영역 (지지물없이 제작)의 미세 형상 편차 형성 메커니즘과 표면 거칠기의 기원을 체계적이고 포괄적으로 조사합니다. 결합 된 DEM-CFD 시뮬레이션 모델은 경계 트랙 윤곽, 분말 접착 및 뒤틀림 변형의 효과를 고려하여 오버행 영역의 용융 풀 역학과 표면 형태의 형성 메커니즘을 나타 내기 위해 개발되었습니다. 표면 거칠기 R의 시뮬레이션 및 단일 요인 L-PBF 인쇄 실험을 사용하여 오버행 각도의 함수로 연구됩니다. 용융 풀의 침몰과 관련된 오버행 영역에서 분말 접착의 세 가지 메커니즘이 식별되고 자세히 설명됩니다. 마지막으로, 인쇄 된 오버행 영역에서 높은 표면 거칠기 문제를 완화 할 수 있는 잠재적 솔루션에 대해 간략하게 설명합니다.

Abstract

본 논문은 자유 표면 효과를 포함한 균일한 흐름 하에서 회전하는 실린더 (로터)에 발생하는 유체 역학적 힘의 실험 테스트 설정 및 측정 방법을 제시합니다. 실험 테스트 설정은 고급 유량 생성 및 측정 시스템을 갖춘 수로 탱크에 설치된 고유 한 구조였습니다.

테스트 설정은 로터 드라이브가 있는 베어링 장착 플랫폼과 유체 역학적 힘을 측정하는 센서로 구성되었습니다. 낮은 길이 대 직경 비율 실린더는 얕은 흘수 강 바지선의 선수 로터 방향타 모델로 선택되었습니다. 로터 역학은 최대 550rpm의 회전 속도와 최대 0.85m / s의 수류 속도에 대해 테스트되었습니다.

실린더의 낮은 종횡비와 자유 표면 효과는 생성 된 유체 역학적 힘에 영향을 미치는 현상에 상당한 영향을 미쳤습니다. 회전자 길이 대 직경 비율, 회전 속도 대 유속 비율 및 양력에 대한 레이놀즈 수의 영향을 분석했습니다. 실험 결과에 대한 계산 모델의 유효성이 표시됩니다. 결과는 시뮬레이션 및 실험에 대한 결과의 유사한 경향을 보여줍니다.

The paper presents the experimental test setup and measurement method of hydrodynamic force generated on the rotating cylinder (rotor) under uniform flow including the free surface effect. The experimental test setup was a unique construction installed in the flume tank equipped with advanced flow generating and measuring systems.

The test setup consisted of a bearing mounted platform with rotor drive and sensors measuring the hydrodynamic force. The low length to diameter ratio cylinders were selected as models of bow rotor rudders of a shallow draft river barge. The rotor dynamics was tested for the rotational speeds up to 550 rpm and water current velocity up to 0.85 m/s. The low aspect ratio of the cylinder and free surface effect had significant impacts on the phenomena influencing the generated hydrodynamic force. The effects of the rotor length to diameter ratio, rotational velocity to flow velocity ratio, and the Reynolds number on the lift force were analyzed. The validation of the computational model against experimental results is presented. The results show a similar trend of results for the simulation and experiment.

결론

결론은 다음과 같습니다.
계산 결과가 일반적으로 실험 데이터와 일치하는 경우 계산 결과는 검증 된 것으로 간주되며 추가 예측에 사용할 수 있습니다. 검증 실험을 통해 메쉬 밀도와 난류 모델을 결정할 수있었습니다.
작은 전류 속도 0.4m / s 및 0.5m / s에서 직경 D3의 로터에 대해 계산 된 양력 값은 회전 속도가 200rpm 이상일 때의 실험 값과 달랐습니다. 그 이유는 실험 중에 관찰 된 강한 진동과 수치 시뮬레이션에서 모델링되지 않은 유동 분리 때문이었습니다.
D2 직경을 가진 로터의 경우 작은 rpm에서 양력의 반대 부호가 관찰되었습니다. 이 현상은 시뮬레이션 중에 관찰되지 않았습니다.
제시된 실험 테스트 설정은 드라이브,지지 구조물 및 측정 장치에 손상을 주지 않고 진동을 포함한 모든 현상을 관찰 할 수 있도록 구성되었습니다. Wang et al. [14]는 동일한 α 값에서 실린더 종횡비가 증가함에 따라 와류 유발 진동이 증가하는 것을 관찰했습니다.
실험의 원활한 진행은 장치 손상 가능성과 함께 약 4의 α에 영향을 미쳤습니다. 본 연구에서는 α = 4.8에서 시작하는 가장 큰 직경의 실린더에서 가장 강한 진동이 관찰되었습니다.
제시된 연구는 로터 생성 흐름의 능동적 제어에 대한 추가 연구의 첫 번째 부분으로 유체 역학적 힘의 신뢰할 수 있는 실험적 예측 방법을 설명했습니다 [22]. , 바람, 파도 [23].
논문의 참신함은 저상 실린더에 대해 회 전자에서 생성 된 유체 역학적 힘을 모델링 할 수있는 가능성에 대한 조사입니다.
이 방법의 주요 장점은 자유 표면 효과 및 유동 유도 회 전자 진동과 관련된 현상을 포함하여 회 전자 생성 유동장 및 유체 역학적 힘을 관찰 할 수 있다는 것입니다. 제안 된 테스트 설정 구성은 유체 역학적 힘의 매개 변수 연구, 스케일 효과 조사 및 낮은 전류 속도와 큰 회전 속도에서 큰 불일치가 확인 된 CFD 시뮬레이션 모델의 검증에 사용될 것입니다.

Abstract

The use of functionalized magnetic particles for the detection or separation of multiple chemicals and biomolecules from biofluids continues to attract significant attention. After their incubation with the targeted substances, the beads can be magnetically recovered to perform analysis or diagnostic tests. Particle recovery with permanent magnets in continuous-flow microdevices has gathered great attention in the last decade due to the multiple advantages of microfluidics. As such, great efforts have been made to determine the magnetic and fluidic conditions for achieving complete particle capture; however, less attention has been paid to the effect of the channel geometry on the system performance, although it is key for designing systems that simultaneously provide high particle recovery and flow rates. Herein, we address the optimization of Y-Y-shaped microchannels, where magnetic beads are separated from blood and collected into a buffer stream by applying an external magnetic field. The influence of several geometrical features (namely cross section shape, thickness, length, and volume) on both bead recovery and system throughput is studied. For that purpose, we employ an experimentally validated Computational Fluid Dynamics (CFD) numerical model that considers the dominant forces acting on the beads during separation. Our results indicate that rectangular, long devices display the best performance as they deliver high particle recovery and high throughput. Thus, this methodology could be applied to the rational design of lab-on-a-chip devices for any magnetically driven purification, enrichment or isolation.

Korea Abstract

생체 유체에서 여러 화학 물질과 생체 분자의 검출 또는 분리를위한 기능화 된 자성 입자의 사용은 계속해서 상당한 관심을 받고 있습니다. 표적 물질과 함께 배양 한 후 비드를 자기 적으로 회수하여 분석 또는 진단 테스트를 수행 할 수 있습니다. 연속 흐름 마이크로 장치에서 영구 자석을 사용한 입자 회수는 마이크로 유체의 여러 장점으로 인해 지난 10 년 동안 큰 관심을 모았습니다. 

따라서 완전한 입자 포획을 달성하기 위한 자기 및 유체 조건을 결정하기 위해 많은 노력을 기울였습니다. 그러나 높은 입자 회수율과 유속을 동시에 제공하는 시스템을 설계하는 데있어 핵심이기는 하지만 시스템 성능에 대한 채널 형상의 영향에 대해서는 덜주의를 기울였습니다. 

여기에서 우리는 자기 비드가 혈액에서 분리되고 외부 자기장을 적용하여 버퍼 스트림으로 수집되는 YY 모양의 마이크로 채널의 최적화를 다룹니다. 비드 회수 및 시스템 처리량에 대한 여러 기하학적 특징 (즉, 단면 형상, 두께, 길이 및 부피)의 영향을 연구합니다. 

이를 위해 분리 중에 비드에 작용하는 지배적인 힘을 고려하는 실험적으로 검증 된 CFD (Computational Fluid Dynamics) 수치 모델을 사용합니다. 우리의 결과는 직사각형의 긴 장치가 높은 입자 회수율과 높은 처리량을 제공하기 때문에 최고의 성능을 보여줍니다.

Abstract

이 연구에서는 비드 운동과 유체 흐름에 미치는 영향에 대한 자세한 분석을 제공하기 위해 연속 흐름 마이크로 채널 내부의 비드 자기 영동에 대한 수치 흐름 중심 연구를 보고합니다.

수치 모델은 Lagrangian 접근 방식을 포함하며 영구 자석에 의해 생성 된 자기장의 적용에 의해 혈액에서 비드 분리 및 유동 버퍼로의 수집을 예측합니다.

다음 시나리오가 모델링됩니다. (i) 운동량이 유체에서 점 입자로 처리되는 비드로 전달되는 단방향 커플 링, (ii) 비드가 점 입자로 처리되고 운동량이 다음으로부터 전달되는 양방향 결합 비드를 유체로 또는 그 반대로, (iii) 유체 변위에서 비드 체적의 영향을 고려한 양방향 커플 링.

결과는 세 가지 시나리오에서 비드 궤적에 약간의 차이가 있지만 특히 높은 자기력이 비드에 적용될 때 유동장에 상당한 변화가 있음을 나타냅니다.

따라서 높은 자기력을 사용할 때 비드 운동과 유동장의 체적 효과를 고려한 정확한 전체 유동 중심 모델을 해결해야 합니다. 그럼에도 불구하고 비드가 중간 또는 낮은 자기력을 받을 때 계산적으로 저렴한 모델을 안전하게 사용하여 자기 영동을 모델링 할 수 있습니다.

Abstract

Super-hydrophobicity is one of the significant natural phenomena, which has inspired researchers to fabricate artificial smart materials using advanced manufacturing techniques. In this study, a super-hydrophobic aluminum surface was prepared by nanosecond laser texturing and FAS modification in sequence. The surface wettability turned from original hydrophilicity to super-hydrophilicity immediately after laser treatment. Then it changed to super-hydrophobicity showing a WCA of 157.6 ± 1.2° with a SA of 1.7 ± 0.7° when the laser-induced rough surface being coated with a layer of FAS molecules. The transforming mechanism was further explored from physical and chemical aspects based on the analyses of surface morphology and surface chemistry. Besides, the motion process of droplet impacting super-hydrophobic surface was systematically analyzed via the optimization of simulation calculation grid and the simulation method of volume of fluid (VOF). Based on this simulation method, the morphological changes, the inside pressure distribution and velocity of the droplet were further investigated. And the motion mechanism of the droplet on super-hydrophobic surface was clearly revealed in this paper. The simulation results and the images captured by high-speed camera were highly consistent, which indicated that the computational fluid dynamics (CFD) is an effective method to predict the droplet motion on super- hydrophobic surfaces. This paper can provide an explicit guidance for the selection of suitable methods for functional surfaces with different requirements in the industry.

Korea Abstract

초 소수성은 연구원들이 첨단 제조 기술을 사용하여 인공 스마트 재료를 제작하도록 영감을 준 중요한 자연 현상 중 하나 입니다. 이 연구에서 초 소수성 알루미늄 표면은 나노초 레이저 텍스처링과 FAS 수정에 의해 순서대로 준비되었습니다.

레이저 처리 직후 표면 습윤성은 원래의 친수성에서 초 친수성으로 바뀌 었습니다. 그런 다음 레이저 유도 거친 표면을 FAS 분자 층으로 코팅했을 때 WCA가 157.6 ± 1.2 °이고 SA가 1.7 ± 0.7 ° 인 초 소수성으로 변경되었습니다.

변형 메커니즘은 표면 형태 및 표면 화학 분석을 기반으로 물리적 및 화학적 측면에서 추가로 탐구 되었습니다. 또한, 초 소수성 표면에 영향을 미치는 물방울의 운동 과정은 시뮬레이션 계산 그리드의 최적화와 유체 부피 (VOF) 시뮬레이션 방법을 통해 체계적으로 분석되었습니다.

이 시뮬레이션 방법을 바탕으로 형태학적 변화, 내부 압력 분포 및 액 적의 속도를 추가로 조사했습니다. 그리고 초 소수성 표면에 있는 물방울의 운동 메커니즘이 이 논문에서 분명하게 드러났습니다.

시뮬레이션 결과와 고속 카메라로 캡처한 이미지는 매우 일관적 이었습니다. 이는 전산 유체 역학 (CFD)이 초 소수성 표면에서 액적 움직임을 예측하는 효과적인 방법임을 나타냅니다.

이 백서는 업계의 다양한 요구 사항을 가진 기능 표면에 적합한 방법을 선택하기 위한 명시적인 지침을 제공 할 수 있습니다.

Introduction

서식지에 적응하기 위해 많은 자연 식물과 동물에서 특별한 습윤 표면이 진화되었습니다 [1-3]. 연잎은 먼지에 의한 오염으로부터 스스로를 보호하기 위해 우수한 자가 청소 특성을 나타냅니다 [4]. 사막 딱정벌레는 공기에서 물을 수확할 수 있는 기능적 표면 때문에 건조한 사막에서 생존 할 수 있습니다 [5].

자연 세계에서 영감을 받아 고체 기질의 표면 습윤성을 수정하는데 더 많은 관심이 집중되었습니다 [6-7]. 기능성 표면의 우수한 성능은 고유 한 표면 습윤성에 기인하며, 이는 고체 표면에서 액체의 확산 능력을 반영하는 중요한 특성 중 하나입니다 [8].

일반적으로 물 접촉각 (WCA) 값에 따라 90 °는 친수성과 소수성의 경계로 간주됩니다. WCA가 90 ° 이상인 소수성 표면, WCA가 90 ° 미만인 친수성 표면 [9 ]. 특히 고체 표면은 WCA가 10 ° 미만의 슬라이딩 각도 (SA)에서 150 °를 초과 할 때 특별한 초 소수성을 나타냅니다 [10-11].

Abstract

The discharge coefficient of morning glory spillway is decreased with eddies created by vortex at the inlet part of weir. However, a series of specific blades can reduce vortices which result in the spillway efficiency is increased. Hence, in this research numerical modeling of installed breaker blade on morning glory spillway was evaluated using Flow-3D model. To achieve these purposes, morning glory spillway was modeled without and with blades 3, 4 and 6 blades at 45 degree angle. To simulate the turbulence fluctuations, the modified k-e model (RNG k-e) was used and its results were compared to the experimental data. Results showed that by installing blades, the discharge coefficient increases up to 42 percent with 25 percent decreasing in the upstream water level. Moreover, among the three different arrangements of blades, the six-blade model was found to have more satisfactory results than other models. In comparison to control model, for H/D between 0 to 0.1 and 0.1 to 0.2 the discharge coefficient has been increased 40 and 57 percent for six-blade arrangement, respectively. 

모닝 글로리의 방류계수는 위어 입구 부분의 와류에 의해 생성된 소용돌이로 감소합니다. 그러나 일련의 특정 블레이드는 와류를 줄여 여수로 효율성을 높일 수 있습니다. 따라서 본 연구에서는 모닝 글로리 여수로에 설치된 브레이커 블레이드의 수치 모델링을 FLOW-3D 모델을 사용하여 평가했습니다. 이러한 목적을 달성하기 위해 모닝 글로리 여수로는 45도 각도로 블레이드 3, 4 및 6 블레이드 있는 모델과 없는 모델로 모델링되었습니다. 난류 변동을 시뮬레이션하기 위해 수정된 k-e 모델 (RNG k-e)을 사용하고 그 결과를 실험 데이터와 비교했습니다. 결과에 따르면 블레이드를 설치하면 상류 수위가 25 % 감소하면서 배출 계수가 42 %까지 증가합니다. 또한 3 개의 서로다른 블레이드 배열 중 6 개 블레이드 모델이 다른 모델보다 더 만족스러운 결과를 나타냈다. 기본 모델과 비교하여 H / D가 0 ~ 0.1 및 0.1 ~ 0.2 인 경우, 6개 블레이드 배열에서 방류계수가 각각 40 % 및 57 % 증가했습니다.

Introduction

Weirs are hydraulic structures used to measure, regulate and control the water levels and are
fixed upon open channels and rivers width. Growing magnitude of probable maximum flood
events (PMF) has highlighted the demand for increasing discharge capacity. Application of
labyrinth weir has been suggested as a solution for increasing discharge capacity.
Tullis et al. (1995) evaluated the effective parameters in determining the capacity of a labyrinth
weir. They introduced total head, the effective crest length and the discharge coefficient as
parameters influencing the discharge capacity of a labyrinth weir. Khode et al. (2011)
experimentally studied the parameters of a flow-over labyrinth weir for different side wall angles
(α) from 8 to 30°. They found that discharge coefficient increases by growing side wall angle
values.
Crookston and Tullis (2012a) studied performance of different labyrinth weirs by making
differences between geometric shapes of weirs in plan. The results indicated that discharge
capacity of the arced labyrinth weirs is more than the discharge capacity of horseshoe weirs.
Seo et al. (2016) investigated the effect of weir shapes on discharge of weirs. It was shown that
the discharge of the labyrinth weir had an increase of approximately 71% in comparison with the
linear ogee weir.
In this research, labyrinth weir with sidewall angle equal to 6° was simulated through Flow3D model, using experimental results of previous researchers. After validation, the changes of
discharge coefficient of weir with angles of 45° and 85° and apex shapes of triangular and halfcircular shapes were analyzed.

Weirs는 수위를 측정, 조절 및 제어하는 ​​데 사용되는 수력 구조물이며 열린 수로 및 강 폭에 고정됩니다. 예상되는 최대 홍수 사건 (PMF)의 규모가 커짐에 따라 배출 용량 증가에 대한 요구가 강조되었습니다. 미로 위어 (labyrinth weir)의 적용은 배출 용량을 증가시키기 위한 해결책으로 제안 되었습니다.

Tullis et al. (1995)는 미로 위어의 용량을 결정하는데 효과적인 매개 변수를 평가했습니다. 그들은 미로 위어의 배출 용량에 영향을 미치는 매개 변수로 총 수두, 유효 문장 길이 및 배출 계수를 도입했습니다.

Khode et al. (2011)은 8 ~ 30 °의 다양한 측벽 각도 (α)에 대한 유동-오버 래비 린스 위어의 매개 변수를 실험적으로 연구했습니다.

그들은 측벽 각도 값이 증가함에 따라 방전 계수가 증가한다는 것을 발견했습니다. Crookston과 Tullis (2012a)는 평면에서 위어의 기하학적 모양을 차이를 만들어 서로 다른 미로 위어의 성능을 연구했습니다.

결과는 호형 미로 위어의 배출 용량이 말굽 위어의 배출 용량보다 더 많다는 것을 나타냅니다. Seo et al. (2016)은 위어의 배출에 대한 위어 모양의 영향을 조사했습니다. 미로 위어의 배출량은 선형 오지 위어에 비해 약 71 % 증가한 것으로 나타났습니다.

이 연구에서는 이전 연구자들의 실험 결과를 사용하여 Flow3D 모델을 통해 측벽 각도가 6 ° 인 미로 위어를 시뮬레이션했습니다. 검증 후 각 45 °, 85 °의 위어의 배출 계수 변화와 삼각형 및 반원 형태의 정점 형태를 분석 하였다.

Irene Par Vahsh Bareh에서 얻은 결과는 다음과 같습니다.

1- 흐름을 따라 포병의 범람 벽 각도를 늘리면 방출 계수가 증가합니다. 벽 각도가 85도 및 45 도인 포병의 범람 계수는 벽 각도가 6 도인 범람 계수 평균의 2.28 및 1.24 배입니다.

2-구부러진 양고기를 먹은 상태에서 배수로 모양의 변화는 배출 계수를 증가시킨다. 삼각형과 비 삼각형 개구부가있는 오버플로의 배출 계수는 온대 개구부가있는 오버플로의 배출 계수에 비해 양고기가 50.29 및 4.16 % 증가했습니다.

3- 오버플로 양 (p / HT)의 부하와 함께 부하 부하의 무 차원 비율 값을 늘리면 혼잡 한 오버플로의 방전 계수가 감소합니다. 또한 p <HT / 0.5의 값에서 세 가지 형태의 오버플로 개구에 대한 배출 계수의 값은 서로 가깝고 오버플로 모양의 각 끝은 값에서 동일한 기능을 갖습니다. p / HT <0.5. 4-유량이 증가함에 따라 유량 계수가 감소합니다.

Al 리본과 Cu 시트의 펄스 레이저 용접은 전력 전자 모듈의 전기적 상호 연결에 대해 조사되었습니다. 결함 없는 Al / Cu 조인트를 얻기 위해 레이저 출력, 스캔 속도 및 열 입력이 서로 다른 다양한 실험 조건이 사용되었습니다. Al / Cu 레이저 용접 중에 금속 간 화합물이 용접 영역에 형성되었습니다. 전자 탐침 마이크로 분석기와 투과 전자 현미경으로 Al4Cu9, Al2Cu, AlCu 등으로 밝혀진 금속 간 화합물의 상을 확인했습니다. 전산 유체 역학 시뮬레이션은 Marangoni 효과가 용융 풀의 순환을 유도하여 혼합물을 생성하는 것으로 나타났습니다. Al과 Cu의 결합과 Al / Cu 조인트에서 소용돌이 모양의 구조 형성. Al / Cu 접합부의 인장 전단강도와 전기 저항을 측정하였으며 용접 면적과 강한 상관 관계를 보였다. Al / Cu 접합부의 용접 면적이 증가함에 따라 기계적 강도의 감소와 전기 저항의 증가가 측정 되었습니다. 또한 무결점 Al / Cu 접합을 위한 공정 창을 개발하고 Al / Cu 레이저 브레이즈 용접을 위한 실험 조건을 조사하여 Al / Cu 접합에서 금속 간 화합물 형성을 최소화했습니다.

Introduction

전기 상호 연결은 전력 전자 모듈을 패키징하는 데 중요합니다. 우수한 기계적 및 전기적 특성을 가진 견고한 전기적 상호 연결은 전력 전자 모듈의 전기적 고장을 방지하는 데 필수적입니다. 저항 스폿 용접, 브레이징, 납땜 및 초음파 용접 (USW)이 전기 상호 연결에 사용되었습니다.

납땜과 납땜 모두 저온 공정으로 인해 접합부에서 한계 변형과 잔류 응력이 발생합니다 [1]. 필러 합금은 두 공정 모두 견고한 전기 접촉을 달성하는 데 필수적입니다. 따라서 조인트는 서로 접촉하는 서로 다른 금속으로 구성됩니다.

결과적으로 조인트는 부식 환경에서 갈바닉 부식에 취약 할 수 있습니다 [2,3]. 더욱이, 비금속과 충전재 사이의 친화도를 고려해야 하기 때문에 제한된 충전재 만 특정 조인트에 사용할 수 있습니다 [1]. USW는 용접 온도가 낮고 용접 시간이 짧기 때문에 접합부의 변형이 비교적 적습니다.

따라서 이는 특히 연질 재료 (예 : Al, Cu, Ag, Au 및 Ni)의 경우 기존 접합 방법을 대체하고 있습니다 [4–6]. 그러나 Cu를위한 USW 공정의 경우, 표면 산화물이 강해 용접성이 저하되는 것을 방지하기 위해 Cu 표면에 Sn 또는 Ni 코팅이 필요하며, 이는 공정 속도를 늦추고 산업적 응용을위한 경제적 측면을 악화시킨다 [7 , 8].

레이저 용접은 쉬운 제어, 고정밀 및 원격 처리의 특성으로 인해 전력 전자 모듈의 전기 연결에 대한 유망한 후보입니다. 열의 영향을 받는 작은 영역과 변형은 전기 접점의 손상을 최소화 할 것으로 예상됩니다 [9-11]. 또한 레이저 용접을 위해 추가 표면 준비가 필요하지 않습니다.

이종 재료의 용접은 산업 응용 분야에서 중요했습니다. 더욱이 그림 1 [12,13]에서 볼 수 있듯이 전기 연결을위한 와이어 또는 리본 본딩에 여러 다른 조인트가 필요하기 때문에 전력 전자 모듈에서 필수적인 기술이되고 있습니다.

전기 접점의 다양한 조합 중에서 Al과 Cu는 높은 전기 전도성으로 인해 전기 연결에 중요한 재료로 종종 간주됩니다 [14]. 그러나 Al과 Cu의 서로 다른 용접은 금속 간 화합물 (IMC)의 형성을 촉진하고 동시에 Al / Cu 조인트의 기계적 및 전기적 특성에 영향을 줍니다. 일반적으로 Al / Cu 조인트 내부에 IMC가 있으면 연성 및 전기 저항에 해를 끼치므로 균열이 쉽게 발생하고 용접을 통한 전기 전도도를 방해합니다 [15,16].

따라서 견고한 Al / Cu 조인트를 얻으려면 IMC의 형성을 피해야합니다. 여러 연구에서 Al 및 Cu 시트의 레이저 빔 용접을 조사했습니다. 연속파 (CW) 레이저가 Al / Cu 조인트에 사용되었습니다 [17-23]. 큰 열 입력과 상당한 IMC 형성으로 인해 용접 영역에서 많은 균열이 관찰되었습니다 [18,19].

CW 레이저 빔의 공간 진동은 Al / Cu 조인트의 용접 품질을 향상시키는 것으로 나타났습니다. 직선 CW 레이저 빔 [18-20]과 비교하여 용접 영역에서 IMC 크기가 더 작은 기공과 균열이 더 적습니다.

Al과 Cu 시트의 겹침 접합에는 CW 단일 모드 파이버 레이저를 사용했으며, IMC 형성을 억제하여 높은 용접 속도 (즉, 50m / min)에서 견고한 Al / Cu 접합을 얻었습니다 [22]. Mai et al. [23]은 다른 Al / Cu 용접을 달성하기 위해 펄스 레이저를 사용했습니다.

그들은 Al / Cu 용접성이 레이저 공정 매개 변수에 크게 의존한다는 것을 밝혔으며 100mm / min 미만의 스캔 속도에서 균열없는 Al / Cu 접합을 달성하는 데 성공했습니다.

Flow-induced Shear Stress Confers Resistance to Carboplatin in an Adherent Three-Dimensional Model for Ovarian Cancer: A Role for EGFR-Targeted Photoimmunotherapy Informed by Physical Stress

난소암에 대한 일관된 3차원 모델에서 카보플라틴에 대한 유동에 의한 전단응력변화에 관한 연구

Abstract

A key reason for the persistently grim statistics associated with metastatic ovarian cancer is resistance to conventional agents, including platinum-based chemotherapies. A major source of treatment failure is the high degree of genetic and molecular heterogeneity, which results from significant underlying genomic instability, as well as stromal and physical cues in the microenvironment. Ovarian cancer commonly disseminates via transcoelomic routes to distant sites, which is associated with the frequent production of malignant ascites, as well as the poorest prognosis. In addition to providing a cell and protein-rich environment for cancer growth and progression, ascitic fluid also confers physical stress on tumors. An understudied area in ovarian cancer research is the impact of fluid shear stress on treatment failure. Here, we investigate the effect of fluid shear stress on response to platinum-based chemotherapy and the modulation of molecular pathways associated with aggressive disease in a perfusion model for adherent 3D ovarian cancer nodules. Resistance to carboplatin is observed under flow with a concomitant increase in the expression and activation of the epidermal growth factor receptor (EGFR) as well as downstream signaling members mitogen-activated protein kinase/extracellular signal-regulated kinase (MEK) and extracellular signal-regulated kinase (ERK). The uptake of platinum by the 3D ovarian cancer nodules was significantly higher in flow cultures compared to static cultures. A downregulation of phospho-focal adhesion kinase (p-FAK), vinculin, and phospho-paxillin was observed following carboplatin treatment in both flow and static cultures. Interestingly, low-dose anti-EGFR photoimmunotherapy (PIT), a targeted photochemical modality, was found to be equally effective in ovarian tumors grown under flow and static conditions. These findings highlight the need to further develop PIT-based combinations that target the EGFR, and sensitize ovarian cancers to chemotherapy in the context of flow-induced shear stress.

전이성 난소 암과 관련된 지속적으로 암울한 통계의 주요 이유는 백금 기반 화학 요법을 포함한 기존 약제에 대한 내성 때문입니다. 치료 실패의 주요 원인은 높은 수준의 유전적 및 분자적 이질성이며, 이는 중요한 기본 게놈 불안정성과 미세 환경의 기질 및 물리적 단서로 인해 발생합니다.

난소 암은 흔히 transcoelomic 경로를 통해 먼 부위로 전파되며, 이는 악성 복수의 빈번한 생산과 가장 나쁜 예후와 관련이 있습니다. 암 성장 및 진행을위한 세포 및 단백질이 풍부한 환경을 제공하는 것 외에도 복수 액은 종양에 물리적 스트레스를 부여합니다. 난소 암 연구에서 잘 연구되지 않은 분야는 유체 전단 응력이 치료 실패에 미치는 영향입니다.

여기, 우리는 백금 기반 화학 요법에 대한 반응과 부착 3D 난소 암 결절에 대한 관류 모델에서 공격적인 질병과 관련된 분자 경로의 변조에 대한 유체 전단 응력의 효과를 조사합니다.

카르보플라틴에 대한 내성은 상피 성장 인자 수용체 (EGFR)의 발현 및 활성화의 수반되는 증가 뿐만 아니라 다운 스트림 신호 구성원인 미토겐 활성화 단백질 키나제/세포 외 신호 조절 키나제 (MEK) 및 세포 외 신호 조절과 함께 관찰됩니다. 키나아제 (ERK). 3D 난소 암 결절에 의한 백금 흡수는 정적 배양에 비해 유동 배양에서 상당히 높았습니다.

포스 포-포컬 접착 키나제 (p-FAK), 빈 쿨린 및 포스 포-팍 실린의 하향 조절은 유동 및 정적 배양 모두에서 카보 플 라틴 처리 후 관찰되었습니다. 흥미롭게도, 표적 광 화학적 양식 인 저용량 항 EGFR 광 면역 요법 (PIT)은 유동 및 정적 조건에서 성장한 난소 종양에서 똑같이 효과적인 것으로 밝혀졌습니다.

이러한 발견은 EGFR을 표적으로하는 PIT 기반 조합을 추가로 개발하고 흐름 유도 전단 응력의 맥락에서 화학 요법에 난소 암을 민감하게 할 필요성을 강조합니다.

Figure 5 The effects of flow-induced shear stress on 3D ovarian cancer biology. (A) Western blot analysis of OVCAR-5 tumors was performed 7 days after culture under static or flow conditions. A flow-induced increase in EGFR and p-ERK, compared to static cultures, was observed. Conversely, a reduction in p-FAK, p-Paxillin, and Vinculin was observed under flow, relative to static conditions. (B) Western blot analysis of 3D OVCAR-5 tumors was performed 11 days after culture under static or flow conditions, including 4 days of treatment with 500 µM carboplatin, and respective controls. In both static and flow 3D cultures, carboplatin treatment resulted in downregulation of EGFR, FAK, p-Paxillin, Paxillin, and Vinculin. Upregulation of p-ERK was observed after carboplatin treatment in both static and flow 3D cultures. (C) Baseline levels of EGFR activity and expression are maintained by a complex array of factors, including recycling and degradation of the activated receptor complex. Flow-induced shear stress has been shown to cause a posttranslational up-regulation of EGFR expression and activation, likely resulting from increased receptor recycling and decreased EGFR degradation. Activation of EGFR results in ERK phosphorylation to induce gene expression, ultimately leading to cell proliferation, survival, and chemoresistance. FAK and other tyrosine kinases are activated by the engagement of integrins with the ECM. Subsequent phosphorylation of paxillin by FAK not only influences the remodeling of the actin cytoskeleton, but also modulates vinculin activation to regulate mitogen-activated protein kinase (MAPK) cascades, thereby stimulating pro-survival gene expression.

생체 유체에서 자성 입자의 연속 흐름 분리 : 마이크로 장치 형상이 분리 성능을 어떻게 결정합니까?

Abstract

The use of functionalized magnetic particles for the detection or separation of multiple chemicals and biomolecules from biofluids continues to attract significant attention. After their incubation with the targeted substances, the beads can be magnetically recovered to perform analysis or diagnostic tests. Particle recovery with permanent magnets in continuous-flow microdevices has gathered great attention in the last decade due to the multiple advantages of microfluidics. As such, great efforts have been made to determine the magnetic and fluidic conditions for achieving complete particle capture; however, less attention has been paid to the effect of the channel geometry on the system performance, although it is key for designing systems that simultaneously provide high particle recovery and flow rates. Herein, we address the optimization of Y-Y-shaped microchannels, where magnetic beads are separated from blood and collected into a buffer stream by applying an external magnetic field. The influence of several geometrical features (namely cross section shape, thickness, length, and volume) on both bead recovery and system throughput is studied. For that purpose, we employ an experimentally validated Computational Fluid Dynamics (CFD) numerical model that considers the dominant forces acting on the beads during separation. Our results indicate that rectangular, long devices display the best performance as they deliver high particle recovery and high throughput. Thus, this methodology could be applied to the rational design of lab-on-a-chip devices for any magnetically driven purification, enrichment or isolation.

생체 유체에서 여러 화학 물질과 생체 분자의 검출 또는 분리를 위한 기능화된 자성 입자의 사용은 계속해서 상당한 관심을 받고 있습니다. 표적 물질과 함께 배양 한 후 비드는 자기적으로 회수되어 분석 또는 진단 테스트를 수행 할 수 있습니다.

연속 흐름 마이크로 장치에서 영구 자석을 사용한 입자 회수는 마이크로 유체의 여러 장점으로 인해 지난 10 년 동안 큰 관심을 모았습니다. 따라서 완전한 입자 포획을 달성하기 위한 자기 및 유체 조건을 결정하기 위해 많은 노력을 기울였습니다.

그러나 높은 입자 회수율과 유속을 동시에 제공하는 시스템을 설계하는데 있어 핵심이기는 하지만 시스템 성능에 대한 채널 형상의 영향에 대해서는 덜 주의를 기울였습니다.

여기에서 우리는 자기 비드가 혈액에서 분리되어 외부 자기장을 적용하여 버퍼 스트림으로 수집되는 Y-Y 모양의 마이크로 채널의 최적화를 다룹니다. 비드 회수 및 시스템 처리량에 대한 여러 기하학적 특징 (즉, 단면 형상, 두께, 길이 및 부피)의 영향을 연구합니다.

이를 위해 분리 중에 비드에 작용하는 지배적인 힘을 고려하는 실험적으로 검증된 CFD (Computational Fluid Dynamics) 수치 모델을 사용합니다.

우리의 결과는 직사각형의 긴 장치가 높은 입자 회수율과 높은 처리량을 제공하기 때문에 최고의 성능을 보여줍니다. 따라서 이 방법론은 자기 구동 정제, 농축 또는 분리를 위한 랩 온어 칩 장치의 합리적인 설계에 적용될 수 있습니다.

Abstract

이 연구에서는 전산 유체 역학 (CFD) 소프트웨어 (FLOW-3D®)를 사용하여 바닥 오리피스가 있는 풀형 어로에서 흐름의 3D 수치 모델링을 수행했습니다. 수치 결과는 음향 도플러 속도계 (ADV) 및 입자 이미지 속도계 (PIV) 측정에서 얻은 실험 데이터와 비교되었습니다.

흐름 깊이, 흐름 패턴, 수속, 난류 운동 에너지, Reynolds 수직 응력 및 바닥 구성 요소에 평행한 Reynolds 전단 응력과 같이 어로 효율에 영향을 미치는 여러 유체 역학적 변수를 정성 및 정량적으로 비교했습니다.

수치 모델은 복잡한 유동장을 정확하게 재현하여 수치 모델 예측과 분석 된 변수에 대한 실험 데이터 사이에 전반적으로 좋은 일치를 보여줍니다. 분석중인 모든 매개 변수에 대한 수치 모델 검증 수행의 중요성이 강조되었습니다.

또한 프로토 타입 어로의 업 스케일 된 수치 모델을 실행하여 스케일링 효과를 분석했습니다. 스케일 효과의 증거없이 실제 모델과 프로토 타입 치수 모두에 대해 유사한 정확도로 모델을 수행했습니다.

현재 연구는 CFD 모델 (즉, FLOW-3D®)이 새로운 수영장 유형 어로 형상을 위한 적절하고 효율적인 설계 및 분석 도구로 사용될 수 있으며 물리적 모델 테스트를 줄이고 보완 할 수 있다고 결론지었습니다.

In this study, the 3D numerical modelling of flow in a pool-type fishway with bottom orifices was performed using computational fluid dynamics (CFD) software (FLOW-3D®). Numerical results were compared with experimental data obtained from acoustic Doppler velocimetry (ADV) and particle image velocimetry (PIV) measurements. Several hydrodynamic variables that influence fishways efficiencies, such as flow depths, flow patterns, water velocity, turbulent kinetic energy, Reynolds normal stresses, and Reynolds shear stress parallel to the bottom component, were qualitatively and quantitatively compared. The numerical model accurately reproduced the complex flow field, showing an overall good agreement between the numerical model predictions and the experimental data for the analysed variables. The importance of performing a numerical model validation for all the parameters under analyses was highlighted. Additionally, scaling effects were analysed by running an upscaled numerical model of the prototype fishway. The model performed with similar accuracy for both physical model and prototype dimensions with no evidence of scale effects. The present study concludes that CFD models (namely FLOW-3D®) may be used as an adequate and efficient design and analysis tool for new pool-type fishways geometries, reducing and complementing physical model testing.Keywords: pool-type fishways; 3D numerical modelling; LES; scale effects; flow patterns; CFD model assessment

Introduction

강의 종단 연결성을 복원하는 것은 담수 생태계의 회복에있어 여전히 중요한 문제입니다 [1,2]. 잘 설계되고 건설된 경우 어로는 물고기가 댐과 둑을 지나 계속 이동할 수 있는 경로를 제공합니다.

물고기 통과 효율성에 대한 검토에서 Noonan et al. [3]은 기존의 많은 어로의 설계 특성이 어종의 요구를 적절하게 충족시키지 못했지만, 풀형 어로가 모든 어류 그룹에 대해 가장 높은 효율성을 보여 주었다는 것을 발견했습니다.
여러 어종에 적합한 수영 조건을 제공하는 것은 어항의 흐름과 난류 패턴이 성공에 중요한 역할을 하기 때문에 다소 어려운 일입니다 [2,4,5,6,7,8,9,10,11,12].

물리적 모델링은 풀형 유형 어로의 유체 역학을 연구하기 위한 주요 접근 방식이었습니다 (예 : [13,14,15,16,17,18,19,20,21,22]). 그러나 물리적 실험은 비용과 시간이 많이 소요됩니다. 따라서 컴퓨터 기술의 발전으로 인해 물리적 모델 테스트를 줄이기 위해 복잡한 기하학적 구조를 가진 유압 구조의 흐름 패턴을 분석하는 데 전산 유체 역학 (CFD) 3 차원 (3D) 모델이 점점 더 많이 사용되고 있습니다 [23,24].

따라서 이러한 모델은 어로 유체 역학 연구 및 효율적인 어로 설계에 필수적인 역할을 할 수 있습니다.
어로에 대한 수치 모델링 연구는 주로 수직 슬롯 어로에 초점을 맞추고 있습니다 [12,25,26,27,28,29,30,31,32,33,34,35,36,37]. 수영장의 주요 부분에서 수직 슬롯 어로 흐름은 거의 2 차원 (2D)이고 수직 속도 구성 요소가 수평 요소 [26]보다 훨씬 작기 때문에 이러한 연구의 대부분은 2D 모델을 사용했습니다.

바닥 오리피스가있는 수영장 유형 어로에서는 흐름이 매우 복잡하고 3D이므로 정확한 유동장 특성화를 얻기 위해 3D 모델을 사용해야합니다. 이 어로 구성을 모델링하는 것은 높은 속도 구배, 높은 와도 및 높은 전단 영역을 포함하기 때문에 다소 어렵습니다.

이 연구에서는 FLOW-3D® (Flow Science, Inc., Santa Fe, NM, USA)를 사용하여 바닥 오리피스가 있는 수영장 유형 어로의 3D 수치 시뮬레이션을 수행하여 흐름 깊이, 속도 및 난류 패턴을 예측하는 능력을 평가했습니다. .

최근 몇 년 동안 실내에 가까운 프로토 타입 수영장 형 어로가 사이프 린드 종의 행동과 움직임을 연구하는데 사용되었습니다 [1,7,8,11,38,39,40,41,42,43]. Silva et al. [38]은 노치, 급락 및 스트리밍에 대한 두 가지 다른 유동 체제와 관련하여 조정 가능한 치수를 가진 침수된 오리피스와 표면 노치의 동시 존재에 대한 Iberian barbel Luciobarbus bocagei (Steindachner, 1864)의 반응을 평가했습니다.

이 연구의 결과는 이베리아 바벨이 어로를 협상하기 위해 오리피스 (76 %)를 선호했으며 어로에 들어가는 데 걸리는 시간도 오리피스에 비해 훨씬 적다는 것을 보여주었습니다.

Silva et al. [39] 오프셋 및 직선 오리피스가있는 수영장 유형 어로의 이베리아 바벨에 대한 적합성을 테스트했습니다. 이 연구는 오프셋 구성이 직선 오리피스 레이아웃 (28 %)에 비해 물고기 통과 성공률 (68 %)이 훨씬 더 높음을 발견했습니다. 어로를 성공적으로 협상하는 데 걸리는 시간도 오프셋 구성, 특히 작은 성인의 경우 훨씬 더 낮았습니다.

이 연구에서는 유속과 난류 매개 변수가 물고기 수영 성능에 미치는 영향을 분석했습니다. 수영장의 유동장을 특성화하기 위해 음향 도플러 속도계가 사용되었습니다.

이 연구의 결과에 따르면 레이놀즈 전단 응력은 어로 내 이베리아 미늘의 움직임에 가장 큰 영향을 미치는 매개 변수임이 입증되었습니다. Branco et al. [40] 두 가지 다른 흐름을 가진 오리피스와 노치가 있는 풀형 유형 어로에서 형태 학적 및 생태학적 특성이 다른 두 종, 바닥 지향 이베리아 바벨 Luciobarbus bocagei 및 물기둥 수영 자 Iberian chub Squalius pyrenaicus의 거동과 성능을 평가했습니다.

풀의 유체 역학을 특성화하기 위해 음향 도플러 속도계가 사용되었습니다. 결과는 두 종 모두 흐름 흐름이있는 노치를 선호했으며 이 흐름 체제로 상류로 이동하는데 더 성공적이었습니다.
이 연구에서는 이 시설의 1 : 2.5 스케일 어로 모델을 사용하여 Silva et al.에 의해 테스트된 바닥 오리피스 구성이 있는 풀형 유형 어로의 속도와 난류를 측정했습니다.

[7,38] 효과가 입증된 바벨 사용. 2D 입자 이미지 속도계 (PIV) 시스템 및 음향 도플러 속도계 (ADV)를 사용하여 순간 속도의 광범위한 측정을 수행하고, 후 처리하고, 수치 모델 정확도를 평가하는 데 사용했습니다.

Haque et al. [44] 대부분의 경우 수치 모델의 검증에 사용할 수있는 실험 데이터 세트에 높은 측정 오류가 있고 / 또는 측정 메시가 너무 거칠어 서 이들의 예측 기능을 올바르게 평가할 수없는 문제를 언급했습니다.

모델. Blocken과 Gualtieri [23]는 검증 및 검증 연구가 필수적이며 CFD 연구를 검증하기위한 데이터를 제공하기 위해 고품질 실험이 필요하다고 언급합니다.

Fuentes-Pérez et al. [35]는 특히 난류 메트릭에 대한 어로 연구에서 수치 모델 검증 데이터를 찾는 데 어려움을 언급합니다. 두 가지 측정 기술을 사용하고 상당한 양의 실험 데이터를 얻었기 때문에 이 연구에서는 이러한 문제를 극복했습니다.

물리적 모델은 종종 Froude 수 유사성을 기반으로하며, 두 유사성 법칙을 모두 충족하는 데 어려움이있어 무시되는 레이놀즈 수 유사성입니다. 프로토 타입 레이놀즈 수가 일반적으로 훨씬 더 크기 때문에 레이놀즈 수 관련 스케일 효과가 도입될 수 있습니다.

레이놀즈 수 증가는 속도 분포와 경계층 속성에 영향을 미칠 수 있습니다 [45]. 척도 효과를 평가하기 위해 수치 시뮬레이션을 사용할 수 있습니다 [46,47]. 따라서 본 연구에서는 바닥 오리피스 흐름이있는 풀형어도에 대한 스케일 효과를 분석하기 위해 두 가지 크기의 수치 모델을 개발했습니다.

프로토 타입 치수의 대형 모델과 물리적 모델 치수의 스케일 된 소형 모델입니다. .
바닥 오리피스가있는 수영장 형 어로의 유동장은 수직 슬롯 어로 (VSF)의 유동장보다 매우 3 차원 적이며 훨씬 더 복잡합니다. 이는 어로 수치 모델 검증에 대한 이전 연구에서 더 자주 고려 된 설계입니다 [26, 27,28,29,35].

저자가 아는 한, 이것은 바닥 오리피스가있는 풀형 어로에 대한 최초의 CFD 연구이며, 여기에는 실험 속도 데이터와 풀형 어로에 대한 3 차원 수치 모델링 결과 간의 가장 광범위한 비교도 포함됩니다. 두 가지 다른 측정 기술 (PIV 및 ADV)이 사용되어 자세한 비교가 가능하고 이러한 유형의 유동장에 대한 CFD 시뮬레이션 결과에 대한 확신을 제공합니다.

이 연구는 다른 어로 유형의 이전 수치 모델 연구에서 제시되지 않았던 난류 매개 변수를 포함하여 수치 모델 결과와 측정 간의 일치에 대한 통계적 테스트를 통해 정성적 비교 뿐만 아니라 상세한 정량적 비교도 제공합니다. 스케일 효과도 다룹니다.

따라서 이 연구는 전 세계적으로 가장 많이 사용되는 풀 유형 어로의 CFD 모델 검증을 원활하게 할 것이며 [10] 설계자들의 사용을 장려 할 것입니다.
또한 새로운 풀 유형 어로 형상을 위한 설계 도구로 CFD 모델 (즉, FLOW 3D®)을 사용하는 방법에 대해 설명합니다.

Abstract

갑작스런 확장 및 바닥 낙하가 있는 고요한 정류지(stilling basin) 유역은 복잡한 수력 특성, 특히 3D 공간 수력 점프 아래에서 변동하는 압력 분포로 이어집니다.

이 논문은 FLOW-3D 소프트웨어를 기반으로 한 LES (Large Eddy Simulation) 모델과 TruVOF 방법을 사용하여 시간 평균 압력, 변동 압력의 RMS (Root Mean Square), 정물(stilling basin) 조 슬래브의 최대 및 최소 압력을 시뮬레이션했습니다.

실제 모델 결과와 비교하여 시뮬레이션 결과는 LES 모델이 정물 유역의 변동하는 수류 압력을 안정적으로 시뮬레이션 할 수 있음을 보여줍니다. 변동 압력의 RMS의 최대 값은 정수조 전면과 측벽의 연장선 부근에 나타납니다.

이 논문은 변동 압력의 생성 메커니즘과 Navier-Stokes 방정식에서 파생된 Poisson 방정식을 기반으로 영향 요인 (변동 속도, 속도 구배, 변동 와도)의 정량 분석과 특성의 정성 분석을 결합하는 연구 방법을 제공합니다.

변동하는 압력의. 정류 지의 소용돌이 영역과 벽에 부착 된 제트 영역의 변동 압력 분포는 주로 각각 와류 및 변동 유속의 영향을 받으며 충돌 영역의 분포는 변동 속도, 속도 구배 및 변동에 의해 발생합니다.

A stilling basin with sudden enlargement and bottom drop leads to complicated hydraulic characteristics, especially a fluctuating pressure distribution beneath 3D spatial hydraulic jumps. This paper used the large eddy simulation (LES) model and the TruVOF method based on FLOW-3D software to simulate the time-average pressure, root mean square (RMS) of fluctuating pressure, maximum and minimum pressure of a stilling basin slab. Compared with physical model results, the simulation results show that the LES model can simulate the fluctuating water flow pressure in a stilling basin reliably. The maximum value of RMS of fluctuating pressure appears in the vicinity of the front of the stilling basin and the extension line of the side wall. Based on the generating mechanism of fluctuating pressure and the Poisson Equation derived from the Navier–Stokes Equation, this paper provides a research method of combining quantitative analysis of influencing factors (fluctuating velocity, velocity gradient, and fluctuating vorticity) and qualitative analysis of the characteristics of fluctuating pressure. The distribution of fluctuating pressure in the swirling zone of the stilling basin and the wall-attached jet zone is mainly affected by the vortex and fluctuating flow velocity, respectively, and the distribution in the impinging zone is caused by fluctuating velocity, velocity gradient and fluctuating vorticity.

The problem of local scouring around circular bridge pier has been studied numerically
by Computational Fluid Dynamics (CFD) using Flow-3D model to represent the evolution of local
scour and the maximum depth of the scour hole which is important in the bridge pier design. The
aim of this study is to verify the ability of the numerical simulation model Flow-3D to accurately
simulate and predict the scour depth around the bridge pier. This verification is conducted by
comparison the numerical results with Melville laboratory experimental model. The maximum
scours depth around the circular pier obtained from numerical results after 30 min is 3.6 cm, while
the scouring depth obtained from Melville model is 4 cm. According to these results, the error rate
ratio between the numerical and experimental models is close to 10%. The results showed a good
validation with experimental results. Finally, the proposed Flow-3D model considered an effective
tool in predicting and simulating the scour depth around bridge pier and considered an economic
method to predict potential results.

scour은 흐르는 물의 침식 작용으로 정의 할 수 있으며, 이는 가까운 교각 및 교각에서 베드를 제거하고 침식합니다 [1]. 다리의 교각 주변을 scour하는 것은 다리의 실패 원인이 충돌 및 과부하와 함께 엄청난 인명 손실과 경제적 영향으로 이어지는 주요 원인 중 하나로 간주됩니다 [2], 지역 scour 예측, 특히 최대 scour 깊이는 다음과 같습니다.

교량 설계, 유지 보수 및 평가에 필수적입니다. 전 세계의 많은 연구자들은 다양한 관점과 다양한 조건에서 광범위하게 scour 문제를 연구했습니다.

교량 부지에서 만든 scour에는 일반적으로 세 가지 유형이 포함되어 있습니다. 일반 scour, 수축 scour 및 국부 scour [3], 세 가지 scour 유형 중, scour는 다리와 관련된 위험에서 가장 중요한 역할을 하기 때문에, local scour는 이 연구의 중요한 부분으로 간주됩니다.

많은 선행 연구가 경험적 테스트를 사용하여 교량의 국부 scour을 분석하는 기술과 방법론을 목표로 했습니다 [4], [5], [6], [7], [8], [9], [10], [11] . 이러한 경험적 scour 테스트의 대부분은 비용이 많이 들고 노동 집약적이기 때문에 크고 중요한 교량에서 종종 수행됩니다.

그러나 가장 인기 있는 고속도로 교량의 경우 경험적 테스트가 적용되지 않지만 이러한 일반 교량에서 scour이 자주 발생하지만 일부 연구에서는 경제적이고 실용적인 목적으로 교량 scour에 대한 분석 솔루션을 조사했습니다.

지난 몇 년 동안 전산 유체 역학 (CFD를 사용하여 산업 및 환경 응용 분야에서 유체 흐름 동작을 결정하는 데 사용)을 더 많이 사용할 수 있는 컴퓨터 및 소프트웨어의 기능이 증가함에 따라 scour의 3 차원 시뮬레이션 방법이 더욱 널리 보급되었습니다.

FLUENT, CFX, PHOENIX와 같은 CFD 소프트웨어는 실험 설정과 여러면에서 유사하므로 이 수치 시뮬레이션의 원래 개념은 속도계와 같은 확장된 부속품을 사용하여 물리적 모델을 설계하고 구성하는 것입니다. 복잡한 모델 실험실 조건에서 모델링하기 어려운 모델은 수치 시뮬레이션을 사용하여 간단하게 모델링 할 수 있습니다.

좋은 수치 모델은 확실히 모델 테스트를 보완 할 수 있으며 설계 엔지니어가 모델 테스트를 수행 할 수 있는 가장 중요한 사례를 식별하는 데 도움이 될 수 있다는 것이 널리 알려져 있습니다.

복잡한 문제와 대규모 모델 연구를 해결할 수 있는 매력적인 아이디어입니다. 실제 결과를 결정하기 위해 추가 작업자 또는 기존의 대규모 설정이 필요하지 않습니다.

CFD (Computational Fluid Dynamics) 방법은 Navier-Stokes의 이산화 및 해석과 계산 셀의 연속성 방정식을 통해 유동 프로세스 시뮬레이션에 항상 사용됩니다. 현재 연구에서 상용 코드 Flow-3D는 교각 주변의 scour 깊이를 모델링하는 데 사용됩니다.

Flow-3D 모델은 유압 공학 응용을 위한 특수 장치가 있는 CFD 패키지입니다. 수치 기법은 다중 스케일 다중 물리 흐름 문제를 얻기 위해 과도 및 3 차원 솔루션에 대한 유체 운동 방정식을 해결하는 데 사용됩니다.

물리적 옵션과 수치 옵션의 조합을 통해 사용자는 Flow-3D를 광범위한 유체 흐름 및 열 전달 현상에 적용 할 수 있으며 다양한 유압 문제를 해결하는 데 널리 사용됩니다 [12]. Flow-3D에 의한 scour의 수치 시뮬레이션은 많은 연구자들에 의해 제안 되었습니다.

Flow-3D에 의한 Scour의 수치 시뮬레이션은 많은 연구자들에 의해 제안 되었습니다.

예를 들어, [13]은 Scour Hole 내의 원형 브리지 부두의 기초에서 발생하는 흐름을 시뮬레이션하기 위해 Flow-3D를 사용했고, [14]는 조수 아래의 복잡한 브리지 피어에서 국소 스캐닝을 시뮬레이션하기 위해 숫자 모델을 사용했고 [15]는 Flow-3D를 사용했습니다.다양한 조건에서 국부적 골절 깊이의 더미 모양과 [16] CFD 코드를 사용하여 3D 흐름과 다양한 모양의 교량 부두 주위의 국부적 스캐닝을 시뮬레이션했습니다.

이 모든 연구는 맑은 물 조건에서 흐르는 물이 주로 흐름과 강바닥 사이의 대부분의 상호 작용으로 이어진다는 가설을 세웠습니다.

본 논문에서는 [4]의 실험실 모델에 의한 수치 시뮬레이션 검증을 통해 교량 주변의 국부 scour 실험 결과를 CFD 코드 Flow-3D의 수치 시뮬레이션 결과와 비교하여 검증을 목적으로 합니다. 이 검증의 주요 목적은 교량 부두 주변의 scour 깊이를 예측할 때 수치 모델 Flow-3D의 효과를 테스트하는 것입니다.

Conclusion

이 연구는 교각에서 scour깊이의 발달을 예측하는 데 있어 이 수치 시뮬레이션의 효과를 검증하는 것을 목표로 합니다. 검증은 30 분의 scour 깊이 공식화 후 Flow-3D의 수치 결과를 Melville 실험 모델과 비교하여 결론을 내립니다.

결과의 비교는 최대 수세공 깊이에 대한 오류율이 10 %임을 나타내며,이 관찰은 수치 및 실험 작업 사이에 좋은 검증을 보여 주므로 수치 시뮬레이션은 scour 깊이를 성공적으로 재현합니다.

이러한 결과에 따르면 제안된 수치 모델 Flow-3D는 교각 주변의 scour 깊이와 유동장을 시뮬레이션하고 예측하는데 효과적인 도구로 간주되었습니다.

Optimization of a Tilt Pour Casting

경동 주조 최적화

최적화 목표

연소 엔진 피스톤의 경동 주조를 최적화하여 공기 혼입을 최소화합니다.

엔지니어링 과제

이 최적화의 목적은 경동 주조 중에 공기 혼입 및 난류의 양을 최소화하는 것입니다. 이 목표는 주물 채우기 모션의 프로필을 수정하여 달성됩니다. 공기 혼입과 난류를 최소화하면 주조에 결함이 발생할 가능성이 줄어 듭니다. 또한 충전 매개 변수를 최적화하면 비용 증가 없이 품질을 높일 수 있습니다.

최적화 전 틸트 타설 주조

최적화 솔루션

사용자가 경동 주조 시뮬레이션의 여러 반복을 실행할 수 있는 워크 플로우를 생성합니다. FLOW-3D (x) 는 노드를 사용하여 최적화를위한 자동화 된 워크 플로를 구성합니다. 세 가지 프로세스 변수 (회전 시작, 회전 지속 시간 및 체적 유량)는 변수 입력으로 사용되며 시뮬레이션이 반복 될 때마다 달라집니다.

FLOW-3D (x) 워크 플로우

Excel 스프레드 시트 노드는 금형 회전의 시작 및 지속 시간과 충전 프로파일의 체적 유량에 대한 테이블을 정의하는 데 사용됩니다. 계산기 노드는 프로파일 설명을 레이들 동작을 규정하는 movin.inp 파일로 변환합니다. 다음으로 FLOW-3D 노드는 시뮬레이션을 실행하는 데 사용됩니다. 각 시뮬레이션의 출력은 후 처리 노드에 의해 결과에서 추출된 총 충전 비율과 동반 공기량 비율입니다. 채우기 비율은 시뮬레이션의 동적 종료 조건으로 사용되어 금형이 완전히 채워지도록 합니다. 최적화 연구에 허용되는 예산 또는 시뮬레이션 수는 30 개로 설정됩니다. 단일 시뮬레이션 실행은 약 15 분입니다.

최적화 결과

사용 FLOW-3D (X) 의 데이터를 분석 도구를 결과 Pareto Front 그래픽 표현이 혼입된 공기의 최소량과 높은 충전 분율 최적 충전 프로파일에 있는 시뮬레이션 대응을 보여준다. 시뮬레이션 및 반복 설계 기능은 모두 FLOW-3D (x)에 의해 자율적으로 생성됩니다 . 또한 각 개별 시뮬레이션의 이미지와 비디오를 출력하도록 설정할 수 있습니다.

다음은 원래의 주입 속도와 주입 시간 (왼쪽)과 오른쪽의 최적화 된 값을 비교 한 것입니다. 주입 속도가 약간 증가하고 주입이 약간 더 일찍 완료됩니다.

원래 주입 속도
최적화 된 주입 속도

다음은 원래 금형 회전 속도 및 기간 (왼쪽)과 오른쪽의 최적화 된 값을 비교한 것입니다. 회전 속도가 증가하고 회전 시간이 원본보다 짧다는 것을 알 수 있습니다.

원래 금형 회전율

Achieve Better CFD Workflows with FLOW-3D (x)

FLOW-3D(x) 는 자동화, 최적화 및 배치 처리를 CFD 워크 플로에 연결하여 CFD를 수행하는 방식을 크게 변화시킵니다. FLOW-3D(x)를 사용하면 자동화 및 최적화 워크 플로우를 그래픽적이고 직관적으로 구축 할 수 있을 뿐만 아니라 Solidworks, Rhino 및 Excel과 같은 외부 프로그램을 연결하여 시뮬레이션에 정보를 동적으로 제공할 수 있습니다. 

설계 매개 변수 공간을 실행하거나 실험 설계에 관심이 있거나 최상의 성능을 위해 형상 부품을 최적화 하는 경우 FLOW-3D(x)를 사용하면 배치 워크 플로우를 구성하고 고급 매개 변수 형상 연구를 수행하며 자동화 및 최적화를 결합하여 신속하게 설계 목표를 충족하고 최적의 해결 방안에 도달할 수 있습니다.

Mixing Tank with FLOW-3D

CFD Stirs Up Mixing 일반

CFD (전산 유체 역학) 전문가가 필요하고 때로는 실행하는데 몇 주가 걸리는 믹싱 시뮬레이션의 시대는 오래 전입니다. 컴퓨팅 및 관련 기술의 엄청난 도약에 힘 입어 Ansys, Comsol 및 Flow Science와 같은 회사는 엔지니어의 데스크톱에 사용하기 쉬운 믹싱 시뮬레이션을 제공하고 있습니다.

“병렬화 및 고성능 컴퓨팅의 발전과 템플릿화는 비전문 화학 엔지니어에게 정확한 CFD 시뮬레이션을 제공했습니다.”라고 펜실베이니아 주 피츠버그에있는 Ansys Inc.의 수석 제품 마케팅 관리자인 Bill Kulp는 말합니다 .

흐름 개선을위한 실용적인 지침이 필요하십니까? 다운로드 화학 처리의 eHandbook을 지금 흐름 도전 싸우는 방법!

예를 들어, 회사는 휴스턴에있는 Nalco Champion과 함께 프로젝트를 시작했습니다. 이 프로젝트는 시뮬레이션 전문가가 아닌 화학 엔지니어에게 Ansys Fluent 및 ACT (분석 제어 기술) 템플릿 기반 시뮬레이션 앱에 대한 액세스 권한을 부여합니다. 새로운 화학 물질을위한 프로세스를 빠르고 효율적으로 확장합니다.

Giving Mixing Its Due

“화학 산업은 CFD와 같은 계산 도구를 사용하여 많은 것을 얻을 수 있지만 혼합 프로세스는 단순하다고 가정하기 때문에 간과되는 경우가 있습니다. 그러나 최신 수치 기법을 사용하여 우수한 성능을 달성하는 흥미로운 방법이 많이 있습니다.”라고 Flow Science Inc. , Santa Fe, NM의 CFD 엔지니어인 Ioannis Karampelas는 말합니다 .

이러한 많은 기술이 회사의 Flow-3D Multiphysics 모델링 소프트웨어 패키지와 전용 포스트 프로세서 시각화 도구 인 FlowSight에 포함되어 있습니다.

“모든 상업용 CFD 패키지는 어떤 형태의 시각화 도구와 번들로 제공되지만 FlowSight는 매우 강력하고 사용하기 쉽고 이해하기 쉽게 설계되었습니다. 예를 들어, 프로세스를 재 설계하려는 엔지니어는 다양한 설계 변경의 효과를 평가하기 위해 매우 직관적인 시각화 도구가 필요합니다.”라고 그는 설명합니다.

이 접근 방식은 실험 측정을 얻기 어려운 공정 (예 : 쉽게 측정 할 수없는 매개 변수 및 독성 물질의 존재로 인해 본질적으로 위험한 공정)을 더 잘 이해하고 최적화하는데 특히 효과적입니다.

동일한 접근 방식은 또한 믹서 관련 장비 공급 업체가 고객 요구에 맞게 제품을보다 정확하게 개발하고 맞춤화하는 데 도움이되었습니다. “이는 불필요한 프로토 타이핑 비용이나 잠재적 인 과도한 엔지니어링을 방지합니다. 두 가지 모두 일부 공급 업체의 문제였습니다.”라고 Karampelas는 말합니다.

CFD 기술 자체는 계속해서 발전하고 있습니다. 예를 들어, 수치 알고리즘의 관점에서 볼 때 구형 입자의 상호 작용이 열 전달을 적절하게 모델링하는 데 중요한 다양한 문제에 대해 이산 요소 모델링을 쉽게 적용 할 수있는 반면, LES 난류 모델은 난류 흐름 패턴을 정확하게 시뮬레이션하는 데 이상적입니다.

컴퓨팅 리소스에 대한 비용과 수요에도 불구하고 Karampelas는 난류 모델의 전체 제품군을 제공 할 수있는 것이 중요하다고 생각합니다. 특히 LES는 이미 대부분의 학계와 일부 산업 (예 : 전력 공학)에서 선택하는 방법이기 때문입니다. .

그럼에도 불구하고 CFD의 사용이 제한적이거나 비실용적 일 수있는 경우는 확실히 있습니다. 여기에는 나노 입자에서 벌크 유체 증발을 모델링하는 것과 같이 관심의 규모가 다른 규모에 따라 달라질 수있는 문제와 중요한 물리적 현상이 아직 알려지지 않았거나 제대로 이해되지 않았거나 아마도 매우 복잡한 문제 (예 : 모델링)가 포함됩니다. 음 펨바 효과”라고 Karampelas는 경고합니다.

반면에 더욱 강력한 하드웨어와 업데이트 된 수치 알고리즘의 출현은 CFD 소프트웨어를 사용하여 과다한 설계 및 최적화 문제를 해결하기위한 최적의 접근 방식이 될 것이라고 그는 믿습니다.

“복잡한 열교환 시스템 및 새로운 혼합 기술과 같이 점점 더 복잡한 공정을 모델링 할 수있는 능력은 가까운 장래에 가능할 수있는 일을 간단히 보여줍니다. 수치적 방법 사용의 주요 이점은 설계자가 상상력에 의해서만 제한되어 소규모 믹서에서 대규모 반응기 및 증류 컬럼에 이르기까지 다양한 화학 플랜트 공정을 최적화 할 수있는 길을 열어 준다는 것입니다. 실험적 또는 경험적 접근 방식은 항상 관련성이 있지만 CFD가 미래의 엔지니어를위한 선택 도구가 될 것이라고 확신합니다.”라고 그는 결론을 내립니다.

천연자원이 계속 감소함에 따라, 대체 자원과 방법을 탐구하고 가능한 한 효과적으로 현재 공급량을 사용하고 있습니다. 엔지니어는 사고를 예방하고 채굴 및 기타 에너지 수확 기법으로 인한 환경적 영향을 평가하기 위해 FLOW-3D를 사용합니다.

Tailing Breach Simulation – CFD Analysis with FLOW-3D

점성이 높은 유체, 비 뉴턴 흐름, 슬러리 또는 심지어 세분화 된 흐름의 형태를 취할 수있는 많은 채광 응용 프로그램의 잔여 물인 테일링은 악명 높은 시뮬레이션 전제를 제공합니다. FLOW-3D  는 비 뉴턴 유체, 슬러리 및 입상 흐름에 대한 특수 모델을 포함하여 이러한 분석을 수행하는 데 필요한 모든 도구를 제공합니다. FLOW-3D 의 자유 표면 유동 모델링 기능 과 결합되어  이러한 어렵고 환경 적으로 민감한 문제에 대한 탁월한 모델링 솔루션을 제공합니다.

관련 응용 분야에는 바람 강제 분석에 따른 광석 비축 더미 먼지 드리프트가 포함되며, 여기서 FLOW-3D 의 드리프트 플럭스 모델을 통해 엔지니어는 광석 침착 및 유입 패턴과 개선 솔루션의 효과를 연구 할 수 있습니다.

액화와 기계적 방해가 물과 같은 뉴턴 흐름과는 대조적으로 입자 흐름의 매우 독특한 속성 인 결국 저절로 멈추는 위반의 동적 특징의 일부라는 점에 유의하십시오.

FLOW-3D  는 기름과 물과 같은 혼합 불가능한 유체를 모델링 할 수 있으며 개방 된 환경 (주변 공기)과 관련된 구성 요소 간의 뚜렷한 인터페이스를 정확하게 추적 할 수 있습니다. 유체는 전체 도메인에 영향을 미치는 역학으로 인해 자유롭게 혼합 될 수 있습니다. 시간이 지남에 따라 유체는 연속 상과 분산 상 간의 드리프트 관계에 따라 다시 분리됩니다. 중력 분리기의 성능은 CFD 모델링을 통해 향상 될 수 있습니다.

생산 파이프 | Production Pipes

생산에 사용되는 공정 파이프의 청소 과정에서 유체가 위로 흘러도 고밀도 입자가 침전될 수 있습니다. 침전 입자를 포착하도록 장치를 설계 할 수 있습니다. 파이프 중앙에 있는 “버킷”이 그러한 잠재적 장치중 하나 입니다. 흐름 변위로 인해 버킷 외부의 상류 속도는 고밀도 입자에 대한 침전 속도보다 높으며 버킷 내부에 모여 있습니다. 표시된 디자인에서 버킷 주변의 상향 유체 속도는 입자 안정화 속도보다 높습니다. 이로 인해 입자가 버킷과 파이프 벽 사이의 틈새를 통해 빠져 나갈 수 없습니다. 따라서 시뮬레이션된 입자는 버킷을 통과하여 아래에 정착하지 않습니다.

진동 수주 | Oscillating Water Column

진동하는 수주는 부분적으로 잠긴 중공 구조입니다. 그것은 물의 기둥 위에 공기 기둥을 둘러싸고 수면 아래의 바다로 열려 있습니다. 파도는 물 기둥을 상승 및 하강시키고, 차례로 공기 기둥을 압축 및 감압합니다. 이 갇힌 공기는 일반적으로 기류의 방향에 관계없이 회전 할 수 있는 터빈을 통해 대기로 흐르게 됩니다. 터빈의 회전은 전기를 생성하는 데 사용됩니다.

아래의 CFD 시뮬레이션은 진동하는 수주를 보여줍니다. FLOW-3D에서 포착한 물리학을 강조하기 위해 중공 구조에서 물기둥이 상승 및 하강하는 부분만 모델링  합니다. 시뮬레이션은 다른 파형 생성 선택을 제외하고 유사한 결과를 전달합니다. 아래의 시뮬레이션은 웨이브 유형 경계 조건을 사용하는 반면 그 아래의 시뮬레이션은  움직이는 물체 모델  을 사용하여 실험실에서 수행한 것처럼 차례로 웨이브를 생성하는 움직이는 플런저를 생성합니다. 각 시뮬레이션에 대해 속이 빈 구조의 압력 플롯이 표시됩니다. 결국 그 압력에 기초하여 터빈이 회전 운동으로 설정되기 때문에 챔버에서 얼마나 많은 압력이 생성되는지 아는 것이 중요합니다.

Architects Achieve LEED Certification in Sustainable Buildings

LEED (Leadership in Energy and Environmental Design)는 제 3자가 친환경 건축물 인증을 제공하는 자발적 인증 시스템입니다.

FLOW-3D는 보고타(콜롬비아)의 사무실 건물에서 “IEQ-Credit2–환기 증가”라는 신뢰를 얻는 데 큰 도움을 주었습니다. 이러한 인정을 받기 위해서는 실외 공기가 ASHRAE의 표준 비율인 30%를 초과한다는 것을 증명해야만 합니다. 이 건물에서 실외 공기는 태양 광선에 의해, 가열되는 지붕 위의 2개의 유리 굴뚝에 의해 발생되는 온도 차이에 의해 발생하는 열 부력의 영향으로 제공됩니다. 이것은 바람이 불지 않는 조건에서 이루어져야 합니다.

Comparing HVAC System Designs

최근 프로젝트에서 Tecsult의 HVAC(난방, 냉방 및 환기)시스템 엔지니어는 강력한 에어컨 시스템의 두 가지 다른 구성을 고려해야 했고 노동자들에게 어떤 것이 가장 쾌적함을 제공하는지 보여주기를 원했습니다. FLOW-3D는 대체 설계를 시뮬레이션하고 비교하는 데 사용되었습니다.

이 발전소는 대형(길이 90m, 너비 33m, 높이 26m)건물로 변압기, 전력선, 조명 등 열 발생 장비를 갖추고 있습니다. 에어컨 시스템의 목적은 건물 내 최대 온도를 35ºC로 제한하는 것입니다. 디퓨저가 하부 레벨에 위치하고 천장 근처의 환기구가 있기 때문에 천장 근처에서 최대 공기 온도가 발생하고 바닥 레벨은 반드시 몇도 더 낮습니다.

이 기사는 FLOW-3D가 원자력 시설에서 봉쇄 시설의 성능을 모델링하는데 사용된 방법을 설명하며, Alion Science and Technology의 Tim Sande & Joe Tezak이 기고 한 바 있습니다.

가압수형 원자로 원자력 발전소에서 원자로 노심을 통해 순환되는 물은 약 2,080 psi 및 585°F의 압력과 온도로 유지되는 1차 배관 시스템에 밀폐됩니다. 수압이 높기 때문에 배관이 파손되면 격납건물 내에 여러 가지 이물질 유형이 생성될 수 있습니다. 이는 절연재가 장비와 균열 주변 영역의 배관에서 떨어져 나가기 때문에 발생합니다. 생성될 수 있는 다양한 유형의 이물질의 일반적인 예가 나와 있습니다(오른쪽).

기계적, 유체적, 광학적 및 전자적 기능을 매우 작은 패키지에 통합한 현대적인 마이크로 유체 장치는 비용, 규모 및 대규모 시스템에 직접 통합하는 능력 면에서 기존 장치에 비해 중요한 장점을 가지고 있다. 3D모델링 및 시각화는 풍부한 기능을 제공하는 효율적인 도구이다. Ivy분석을 통해 연구 시간, 설계 및 생산 비용을 크게 절감할 수 있습니다. 마이크로, 바이오 및 나노 유체 역학은 FLOW-3D의 자유 표면 및 다중 유체 모델링 기능으로 쉽고 정확하게 시뮬레이션할 수 있습니다. 이 섹션의 시뮬레이션을 통해 보다 잘 이해할 수 있는 다양한 애플리케이션과 프로세스를 살펴보시기 바랍니다.

FLOW-3D는 시각적 관찰과 양호한 정량적 추세 예측을 바탕으로 우수한 정성적 합의를 제공했습니다. 마찬가지로 중요한 것은 소프트웨어가 설계 민감도를 정확하게 예측한다는 점이다. 그 결과, FLOW-3D는 Kodak의 고급 연구 개발 작업을 지원하는 데 유용한 통찰력을 제공했습니다.

Fig. 2: Scheme of the LED photo-crosslinking and 3D-printing section of the microfluidic/3D-printing device. The droplet train is transferred from the chip microchannel into a microtubing in a straight section with nearly identical inner channel and inner microtubing diameter. Further downstream, the microtubing passes an LED-section for fast photo cross-linking to generate the microgels. This section is contained in an aluminum encasing to avoid premature crosslinking of polymer precursor in upstream channel sections by stray light. Subsequently, the microtubing is integrated into a 3D-printhead, where the microgels are jammed into a filament that is directly 3D-printed into the scaffold.

자기 혈액 정화 마이크로 장치의 최적화

Separation of toxins with magnetic particles. Why is it so important?

자성 입자와 독소의 분리. 왜 그렇게 중요한가?

자성 입자의 사용은 최근 독성 물질의 혈류에서 다른 독소가 체외로 포획되는 해독 (disoxification) 과정으로 확대되었습니다. 생체 유체의 해독은 많은 수의 임상 상태에서 가장 생각할 수있는 치료법이며, 일부는 패혈증과 같은 높은 사망률과 관련이 있습니다. 이것은 혈류를 통해 퍼지면서 신체의 방어력을 압도하는 미생물 감염에 의한 치명적인 질병입니다. 이는 미국 내에서만 연간 1800 만 명의 사람들에게 고통을주고 매년 20 만 명이 넘는 사망을 초래하는 병원 중환자 실에서의 주요 사망 원인을 나타냅니다. 정확한 치료를 시행하기 전에 사망률이 매 시간마다 9 % 나 증가한다는 것을 볼수 있습니다. 따라서 최첨단 병원 중환자 실에서도 독소를 신속하게 제거하는 것이 가장 중요합니다.

우리는 현재 치료법의 한계가 독소 격리 제로서 자성 비드를 사용하는 것과 같은 새로운 전략의 개발을 필요로한다는 것을 발견했습니다. 입자의 자기 적 특성으로 인해 병원체의 포획이 완료되면 영구 자석에 의해 생성 된 외부 자기장을 사용하여 환자의 혈액과의 분리가 연속적으로 수행 될 수 있습니다. 지난 10 년 동안 개발 된 다중 자기 마이크로 세퍼레이터로부터 우리는 2 상 연속 흐름 시스템의 사용을 제안했습니다. 이러한 시스템은 흐름 제한 및 생체 유체의 임의의 분해 (즉, 포획 영역 내의 세포의 비특이적 포획)가 회피되어 시간 경과에 따른 시스템의 효능 및 용량을 유지하기 때문에 최선의 대안일 것입니다 [1]. 그러나 이러한 프로세스의 최적화는 덜 연구되었고 합리적 설계는 종종 수학적 설명과 관련된 복잡성으로 인해 부족합니다. 따라서 우리는 체외 해독 과정의 설계를 최적화하기 위해 FLOW-3D로 다중 위상 시스템 내부의 흐르는 혈류로부터 자기 구슬의 분리를 모델링했습니다. 그림1에 나타난 제안된 분리기 디자인에서, 비드는 상부 입구를 통해 연속적으로 주입되고, 자기 구배의 적용에 의해 편향되고 유동 버퍼 스트림으로 수집됩니다. 유체 위상의 혼합을 피하면서 효율적인 분리를 달성하기 위해, 자력 및 유체력을 신중하게 연구하고 최적화했습니다. 구슬이 편향 될 때 입자 – 유체 상호 작용에 대한 상세한 연구도 제공됩니다.

그림 1. 제안 된 microfluidic bioseparator의 도식 다이어그램 ([2]에서 채택).

Modeling approach with FLOW-3D

첫번째로 보여지는 생체 분리기 내부의 자기 영동 입자 수송을 예측하기위한 모델은 CFD 기반의 오일러 – 라그랑지안 (Eulerian-Lagrangian) 접근법으로 구성됩니다. Navier-Stokes 방정식을 풀어서 예측 한 유체 이동은 오일러 접근법을 사용하여 계산되지만, 우리는 비드 역학을 모델링하기 위해 라그랑지안 프레임 워크를 사용했습니다. 라그랑지안 (Lagrangian) 접근법에 따르면 입자는 개별 단위로 모델링되었으며 각각의 궤도는 고전적인 뉴턴 역학을 적용하여 추정되었습니다. 분리 동안 입자에 작용하는 힘은 다르지만 영구 자석에 의해 생성 된 자기 구배 하에서 비드 궤적을 예측하기위한 지배적 인 자력 및 유동력만 고려했습니다. 유체의 동일한 유입 속도를 유지하면서 채널의 하부 벽과 자석의 상단 사이의 거리를 변화시킴으로써 다른 입자 궤적 및 따라서 분리 효능을 얻었습니다 (버퍼에 대해 0.035mS-1, m • s-1). 우리가 개발 한 모델링 노력에 대한 자세한 내용은 출판 된 연구 [1, 2]에서 찾을 수 있습니다.

그림 2. 자석과 마이크로 채널 사이의 거리 “d”를 변화시킴으로써 제공되는 서로 다른 자기장 하에서의 입자 궤적 (빨간색 선) ([2]에서 채택). 윤곽 플롯은 채널에서 예상되는 평균 유체 속도 크기를 나타냅니다.

입자 자기 영동 결과

자석의 위치를 ​​변화시킴으로써, 우리는 가변 자장 구배가 발생하고, 따라서 상이한 분리 효율이 얻어짐을 입증했습니다. 그림 2는 자석과 채널 사이의 거리 d가 다른 입자의 궤도를 보여줍니다. 0 ~ 1mm 사이의 거리에서 모든 입자는 입구에서 원래 위치와 별개로 분리됩니다. 더 큰 거리의 경우, 낮은 자기력으로 인해 분리가 불완전합니다. 완전한 입자 분리를 위해서는 중 ~ 고 자력이 필요합니다. 그러나, 우리는 높은 자력이 유체 패턴의 섭동과 유체 계면의 파손으로 이끄는 입자의 극도의 가속으로 인해 해독 목적에 바람직하지 않음을 입증했습니다 (그림 3 참조). 따라서 중간 자력이 나타나게됩니다. 완전한 비드 분리가 혈액의 완전성을 유지하면서 달성 될 수 있기 때문에 이러한 종류의 시스템에 가장 적합할 수 있습니다.

그림 3. 입자가 a) d = 0 mm 및 b) d = 1.15 mm에 대해 상간 경계면을 횡단 할 때의 속도 벡터. c) d = 0 mm 및 b) d = 1.15 mm ([2]에서 채택)에 대한 그 당시의 혈액 체적 분율.

Conclusions

본 연구에서는 다중 위상 연속 흐름 마이크로 디바이스에서 혈액으로부터 자기 비드 분리 과정을 예측하고 최적화 하기위한 새로운 FLOW-3D 모델을 소개했습니다. 이 모델은 입자에 작용하는 우세한 힘을 고려하고 개별 입자의 궤도, 분리에 필요한 시간 및 혈액 / 버퍼 동시 흐름의 섭동을 포함하여 분리 과정의 중요한 세부 사항을 연구하는데 사용될 수 있습니다 . 이 연구의 핵심 요소는 유체 장에서 입자 – 유체 상호 작용의 영향을 고려하면서 장치에서 동시에 흐르는 두 유체 간의 상호 작용을 연구 한 것입니다. 솔루션이 채널의 길이를 따라 독립적으로 흐르고 각각의 출구에서 분리되어 가능한 혈액 손실이나 용해를 피하기 때문에 이러한 문제는 매우 중요합니다. 여기에 이어지는 방법론은 핵심 작동 변수 및 매개 변수를 고려하여 입자 분리를 예측하는 데 사용할 수 있으므로 합리적인 설계 지침을 제공합니다. 일반적으로 혈액 해독 과정뿐만 아니라 미세 유체 장치 내부에 여러 개의 구속 된 액체 상을 포함하는 다른 연구를위한 파라 메트릭 분석 및 최적화에도 적용됩니다. 우리의 미래 연구는 새로운 혈액 해독 과정을 설계하기 위해 전혈을 사용하는 과정의 실험적 분석과 자성 분리 단계의 독소 제거와 통합에 초점을 맞출 것입니다.

Sturgeon Navigate Fish Ladder

Sturgeon Navigate Fish Ladder

 

This material was provided by Jean-François Mercier, ing., Manager, hydraulics and hydrology at AECOM Tecsult inc.

AECOM Tecsult inc.은 FLOW-3D를 이용하여 물리적 모델링을 사용하지 않고 철갑상어가 Fish ladder를 탐색할 수 있는 물고기 사다리 설계를 개선했습니다. 실험은 현장구현의 제한과 비용때문에 배제되었고 FLOW-3D의 수치 모델링 결과로 정확한 정보를 제공하는 것이 중요했습니다.

Fish ladder는 James Bay, Quebec, Canada의 이스트 메인 강에 2005~2006년사이에 지어졌습니다. 2006년과 2007년에 실시된 후속 연구는, 다른 종의 물고기들이 이 사다리를 오를 수 있었던 반면, 철갑상어는 실패한 경우를 보여주었습니다. 기존의 Fish ladder에서 두 가지의 문제가 발견되었습니다. AECOM Tecsult inc에서의 물고기의 낮은 어획과 물의 빠른 속도가 문제가 되었습니다. 엔지니어들은 이러한 문제에 대한 해결책을 찾기 위해 FLOW-3D로 수치 모델링 연구를 수행하기로 결정했습니다.

 

Redesigning the fish ladder                          

AECOMTecsultinc. 엔지니어들은 물고기 사다리에 대한 최적의 설계 변경을 결정하기 위해 세가지 모델을 실행했습니다.

  • 유인을 극대화할 수 있는 강과 물고기 통로 사이의 흐름 분포를 평가하는 지역모델. 산란기 동안의 정상적인 조건에서 물고기 통로는 22m3/s의 유량흐름이 나타난다.
  • 슬롯 및 디플렉터의 개조를 위한 로컬 모델
  • 전체 길이에 걸쳐 수위 균형 유지를 위한 통로모델

Fish ladder specifications (before renovation)

Flow in fish passage before design optimization work

  • Length = 150 m
  • 17 basins
  • Drop = 3 m
  • Peak velocities of 2.6 m/s

Figure 1 – 45% of flow in fish passage shows velocities that are too high for the sturgeon to navigate

Figure 2 – 10% of flow in fish passage shows below the 1.8 m/s criteria required for sturgeon to navigate

Figure 3 – Tests were made with different additions of blocks (pink) and deflector plates (black) to find an optimum configuration

 

Validation of the numeric model

CFD모델을 실행한 후 엔지니어는 실험 데이터에 대해 숫자 결과를 검증했습니다. Flow-3D결과는 표면 높이를 비교하는 수문 기록과 비교되었습니다. 124개 중 80%가 유속이 일치했습니다.  동일한 위치 점에서 일치하지 않는 곳은 난류 영역이었습니다.

Velocity comparisons of measured data and FLOW-3D at specific locations

 

Meeting the criteria — modifications to flow rates

엔지니어들은 물고기가 곧장 바다로 가지 않도록 흐름을 15~20%로 줄이기 위해 Fish ladder를 개조하기로 결정했습니다. 그림 2는 그림과 비교하여 물고기 통로의 10% 유량으로 현저한 속도 감소를 보여 줍니다. 물고기 통로에 흐름의 45%를 가진 1. 그림 3은 흐름 속도를 늦추기 위한 블록 및 디플렉터를 보여 줍니다. 설정된 기준의 최대 속도는 1.8m/s 였습니다. 전체 흐름 조건은 그림 1과 2에서와 같이 모델로 잘 표현됩니다.

 

Conclusion

AECOM Tecsult inc 엔지니어들은 그들의 숫자 모델의 정확성을 검증할 수 있었고 FLOW-3D로부터 얻은 정보를 사용하였고 물고기 통로를 재설계하여 테스트와 관련된 높은 비용을 피할 수 있었습니다. 2008년 여름에 있었던 후속 연구에 따르면 철갑 상어가 높은 유량에도 불구하고 성공적으로 물고기 통로를 통과하고 있다는 것을 보여 주었습니다.

Investigation of Mould Leakages in a Gravity Casting

Investigation of Mould Leakages in a Gravity Casting

Metal leakages in the original gravity casting mould

몰드 설계는 유체 역학과 금속 응고 패턴뿐만 아니라 주형 자체에서 발생할 수 있는 문제와 응력에 대한 반응을 고려해야 하는 매우 복잡한 작업입니다. 이탈리아에 본사를 둔 주형 제작 업체인 CMTaricco 사는 최근에 새로운 주형 중 하나의 하부에서 금속 누출 문제에 직면했습니다. 주형 누출의 원인은 처음에는 분명하지 않았으며 몇 번의 공정 주기 후에만 나타났습니다. 제작 일정에 차질이 생기고 부품 주조 비용이 급격히 증가하기 때문에 문제가 중요한 것은 분명했습니다.

Investigation of an idea

공정 자체는 주입과 오버플로우 설계인 중력 주조 방식이었기 때문에 유체 역학 부분에서는 문제가 발생할 수 없었습니다. GabrieleTaricco (CMTaricco의 소유주)의 가설은 금속 누출이 주형의 열 손실의 설계 불량에서 기인하여 균일하지 않은 분포를 초래한다는 것이었습니다. 변형률과 그에 따라 주형 바닥에서 크고 원하지 않는 변형이 순환하면서 금속이 유출될 수 있는 중요한 영역의 개방까지 주기적으로 시행되었습니다. 이를 확인하고 문제에 대한 신속한 해결책을 찾기 위해 FLOW-3D시뮬레이션을 실행하여 주형이 가열될 때 발생하는 현상을 정확하게 파악했습니다.

A careful setup, to achieve a fast resolution of the issue

문제의 원인은 신속하게 파악할 수 있어야 했기 때문에 최신 Flow-3D기능을 모두 활용하여 정확한 설정이 필요했습니다. 특히, 채택된 meshing기법은 전통적인 설정과 거의 동일한 정확도를 유지하면서 전산 셀의 수를 크게 줄이는데 매우 도움이 되었습니다. 빠른 시뮬레이션으로 주형 세척에 사용된 첫 번째 방법은 주형 내부의 얇은 캐비티를 직교 축과 정렬하기 위해 주형을 수직 축 주위로 회전시키는 것이었습니다.

두 번째 트릭은 내부 공동 (얇은 벽)에 new conformal mesh기능을 사용하는 한편 전체 도메인에 대해 기존의 더 큰 메쉬 블록을 유지하는 것 이었습니다. The conformal mesh는 open volume과 일치하고, 작은 간극을 갖는 cavity로 제한됩니다.

마지막으로, 외부 공간을 주형에 제한하기 위해(현재 구두 상자 모양이 되고, 20도 회전하며, 모델 축과 정렬상태) 일부’ 도메인제거’ 요소가 사용되었습니다.즉, FLOW-3D의 내부 솔리드 모델을 통해 직접 연결됩니다

나머지 설정은 소프트웨어의 권장 기본값 대부분을 이용하여 기존 체계를 따랐습니다. 이러한 기능과 FLOW-3D의 새로운 하위 도메인 분해 기능 덕분에 설계된 9 000 000 셀을 유체 하위 도메인의 경우에만 1 840 000 셀로, 고체 서브 도메인의 경우 2 430 000 셀로 줄이는 것이 가능했습니다.

 

The analysis

주입 시뮬레이션 후, 양호한 주입 패턴을 보장하기 위해 시뮬레이션의 초점이 열 다이 사이클링 분석으로 리디렉션 되었습니다. 이 경우 설정은 일반 데스크 톱 컴퓨터에서 10개의 생산 사이클을 재현하는 데 1시간이면 간단하고 빠릅니다(i7930 K, 상업적 가치 1500달러). 그 결과 CM의 초기 가설이 확인되었습니다. FlowSight를 사용하여 단일 이미지에서 여러 시점과 횡단면에서 온도 필드를 관찰한 결과 온도가 d라는 것이 분명했습니다. 주형의 침입은 예상되는 변형과 금속 누출을 쉽게 유발할 수 있습니다.

Further analysis with the Fluid-Structure Interaction module

 

일단 문제가 확인되고 기술 요원이 향상된 금형 설계를 시작하면 CM Taricco는 다이 상의 응력 및 변형에 대한 FEM 해석을 실행하는 최종 확인을 원했습니다. 이 분석을 수행하기 위해 XC Engineering Srl은 CM이 계산을 설정하고 수행하는 것을 도왔습니다. 분석의 결과는 정확히 CM이 생각하고 있는 것을 보여주었습니다. FLOW-3D는 붓기가 거의 걸리지 않은 금형에서 발견 된 실제 변형과 동일한 위치와 크기를 극도의 정확도로 재현 할 수 있었습니다. 이것은 CM에 대한 좋은 소식이었으며, 실제 주조 조건을 기반으로 실제 금형 변형을 예측하기 위해 설계 단계에서 FSI 모듈을 사용하는 추가 권장 사항을 시행했습니다.

Conclusion

해석결과, CM직원은 CFD솔루션의 온도영역에 대한 모든정보를 사용하여 최적화된 새로운 주형을 설계할 수 있었습니다. 새로운 주형은 열 에너지를 보다 효율적인 방법으로 방출할 수 있었으며 주조물은 수 십번의 공정 주기 후에도 금속 누출의 영향을 받지 않았습니다.

Sturgeon Navigate Fish Ladder

Sturgeon Navigate Fish Ladder

 

This material was provided by Jean-François Mercier, ing., Manager, hydraulics and hydrology at AECOM Tecsult inc.

AECOM Tecsult inc.은 FLOW-3D를 이용하여 물리적 모델링을 사용하지 않고 철갑상어가 Fish ladder를 탐색할 수 있는 물고기 사다리 설계를 개선했습니다. 실험은 현장구현의 제한과 비용때문에 배제되었고 FLOW-3D의 수치 모델링 결과로 정확한 정보를 제공하는 것이 중요했습니다.

Fish ladder는 James Bay, Quebec, Canada의 이스트 메인 강에 2005~2006년사이에 지어졌습니다. 2006년과 2007년에 실시된 후속 연구는, 다른 종의 물고기들이 이 사다리를 오를 수 있었던 반면, 철갑상어는 실패한 경우를 보여주었습니다. 기존의 Fish ladder에서 두 가지의 문제가 발견되었습니다. AECOM Tecsult inc에서의 물고기의 낮은 어획과 물의 빠른 속도가 문제가 되었습니다. 엔지니어들은 이러한 문제에 대한 해결책을 찾기 위해 FLOW-3D로 수치 모델링 연구를 수행하기로 결정했습니다.

 

Redesigning the fish ladder                          

AECOMTecsultinc. 엔지니어들은 물고기 사다리에 대한 최적의 설계 변경을 결정하기 위해 세가지 모델을 실행했습니다.

  • 유인을 극대화할 수 있는 강과 물고기 통로 사이의 흐름 분포를 평가하는 지역모델. 산란기 동안의 정상적인 조건에서 물고기 통로는 22m3/s의 유량흐름이 나타난다.
  • 슬롯 및 디플렉터의 개조를 위한 로컬 모델
  • 전체 길이에 걸쳐 수위 균형 유지를 위한 통로모델

Fish ladder specifications (before renovation)

Flow in fish passage before design optimization work

  • Length = 150 m
  • 17 basins
  • Drop = 3 m
  • Peak velocities of 2.6 m/s

Figure 1 – 45% of flow in fish passage shows velocities that are too high for the sturgeon to navigate

Figure 2 – 10% of flow in fish passage shows below the 1.8 m/s criteria required for sturgeon to navigate

Figure 3 – Tests were made with different additions of blocks (pink) and deflector plates (black) to find an optimum configuration

 

Validation of the numeric model

CFD모델을 실행한 후 엔지니어는 실험 데이터에 대해 숫자 결과를 검증했습니다. Flow-3D결과는 표면 높이를 비교하는 수문 기록과 비교되었습니다. 124개 중 80%가 유속이 일치했습니다.  동일한 위치 점에서 일치하지 않는 곳은 난류 영역이었습니다.

Velocity comparisons of measured data and FLOW-3D at specific locations

 

Meeting the criteria — modifications to flow rates

엔지니어들은 물고기가 곧장 바다로 가지 않도록 흐름을 15~20%로 줄이기 위해 Fish ladder를 개조하기로 결정했습니다. 그림 2는 그림과 비교하여 물고기 통로의 10% 유량으로 현저한 속도 감소를 보여 줍니다. 물고기 통로에 흐름의 45%를 가진 1. 그림 3은 흐름 속도를 늦추기 위한 블록 및 디플렉터를 보여 줍니다. 설정된 기준의 최대 속도는 1.8m/s 였습니다. 전체 흐름 조건은 그림 1과 2에서와 같이 모델로 잘 표현됩니다.

 

Conclusion

AECOM Tecsult inc 엔지니어들은 그들의 숫자 모델의 정확성을 검증할 수 있었고 FLOW-3D로부터 얻은 정보를 사용하였고 물고기 통로를 재설계하여 테스트와 관련된 높은 비용을 피할 수 있었습니다. 2008년 여름에 있었던 후속 연구에 따르면 철갑 상어가 높은 유량에도 불구하고 성공적으로 물고기 통로를 통과하고 있다는 것을 보여 주었습니다.

 

 

High Pressure Die Casting

High Pressure Die Casting

HPDC(High Pressure Die Casting)는 주조 시뮬레이션 소프트웨어의 가장 큰 당면 과제 중 일부입니다. FLOW-3D CAST는 사용자가 매우 정확한 TruVOF를 포함하여, 채우기 프로세스를 비판적으로 분석할 수 있도록 금형 채우기 시뮬레이션의 정확성을 크게 향상시키는 몇 가지 기능을 가지고 있습니다. 움직이는 금속 전면을 추적하기 위한 알고리즘과, 일반적으로 고압 다이캐스팅과 관련된 복잡한 형상을 정확하게 나타내는 FAVOR™ 또한 FLOW-3D CAST는 공기 침입, 미세 기공, 접힘 및 개재물 등의 결함을 탐지하기위한 수많은 모델을 보유하고 있습니다.

Thermal Die Cycling

수천개의 주물을 생산하기 위해 동일한 금형을 반복적으로 사용하기 때문에, 고압 다이캐스팅에는 열 다이 사이클 시뮬레이션이 필수적입니다. 금형의 뒤틀림으로 인해 금형 온도가 일정하게 유지되어 치수 불안정을 초래합니다. FLOW-3D CAST를 사용하면 다이 가열, 분사 및 공기 블로우-오프 효과와 냉각 채널 및 삽입물의 위치를 적절하게 예상해서 온도 분포 결과가 정확하고 효과적일 수 있습니다

Shot Sleeve Optimization

고압 다이캐스팅 시, 샷 실린더는 용탕을 신속하게 금형 안으로 밀어 넣습니다. 수평 방향으로 향하여, 용탕은 상단의 주입구를 통해 그 안으로 주입되고 피스톤은 용탕을 실린더 아래로 밀어낸다. 올바르게 설계된 샷 슬리브 프로파일의 목적은 용탕을 금형에 최대한 빨리 밀어 넣어, 불완전하거나 결함 있는 주입을 유발하는 조기 응고를 방지하는 것입니다. 그러나 피스톤이 너무 빠르게 움직이면 용탕이 접혀 최종 주조 부품에 내부 결함으로 나타날 수 있는 공기가 갇힙니다.

FLOW-3D CAST를 사용하여 몇 분 내에 여러 샷 프로파일을 계산할 수 있습니다. 여기에 표시된 것은 두가지 샷 프로파일의 시뮬레이션입니다. 일정한 속도의 2단계 프로세스와 FLOW-3D CAST내에서 상당한 차이를 보이는 점진적 가속 데이터로 계산된 또 다른 것입니다.

Filling Simulations

가장 복잡한 고압 다이캐스팅 문제는 용탕이 고압에서 고속으로 금형 내부로 들어갈 때 용탕을 정확하게 추적하는 것입니다. 이로 인해 용탕이 공동 현상에 튀는 것은 소프트웨어의 결함 예측에 상당한 어려움을 겪게 됩니다. TruVOF 방법을 사용하면 게이트의 위치를 파악하여 최적의 흐름 패턴, 오버 플로우의 위치 및 초기 응고 현상과 결함 여부를 확인할 수 있습니다.

Modeling Solidification

FLOW-3D CAST는 엔지니어가 최종 부품의 품질에 영향을 미칠 수 있는 내부 다공성의 형성을 조사하는 데 도움이 됩니다. 또한 FLOW-3D CAST를 사용하면 이종 합금의 편석에 대한 조사가 가능합니다. 마지막으로, 온도 이력에 대한 자세한 설명을 통해 냉각 라인을 추가해야 하는지 또는 추가해야 하는지 여부와 초기 금속 온도를 변경해야 하는지 여부를 판단할 수 있습니다. FLOW-3D CAST를 통해 엔지니어는 내부 기공, 열응력 및 이종 합금 편석의 형성 여부를 조사할 수 있습니다.

HPDC (High Pressure Die Casting, 고압다이캐스팅)

HPDC (High Pressure Die Casting, 고압다이캐스팅)

주조 기술 중 하나인 고압 다이 캐스팅 해석시 다른 많은 주조해석 소프트웨어에서 큰 문제들이 나타납니다. 충진되어야 할 부분은 대부분 매우 얇은 두께를 가지고 있어서 형상 구현에 필요한 격자의 수가 크게 증가되어야 합니다. 무엇보다도 금속은 높은 압력과 매우 빠른 속도로 금형안의 빈 공간에 충진됩니다. 금형 내부로 분사되고 비산하는 유동은 이 과정에서 혼입 된 공기로 인한 기포결함, 제품이 완전히 충진되기 전에 냉각이 시작하면서 발생하는 탕주름과 산화물 결함으로 이어질 수 있습니다.  FLOW-3D는 실질적인 금형 충진 해석의 정밀도를 향상시키기 위해 정확성이 고도로 향상된 TruVOF™ 추적기법과 복잡한 형상을 모델링하는FAVOR ™ 기법을 포함하고 있습니다. 또한 FLOW-3D는 혼입 된 공기, 열 응력, 미세 결함 영역을 검출하기 위한 다양한 모델을 가지고 있습니다.

Thermal Die Cycling (금형온도분포,  금형싸이클링)

Die cycling 해석은 다이캐스팅 금형이 수천 개의 제품 생산에 반복적으로 사용되기 때문에 고압 다이 캐스팅에 필수적인 공정입니다. 생산시 모든 주조품에 대해서 동일한 금형 온도를 유지하는 것은 매우 중요한데, 이는 금형온도에 따라 주조품의 결괌이 발생할 수 있기 때문입니다. FLOW-3D는 다이캐스팅 싸이클에서 발생하는  금형 가열(충진, 응고), 스프레이, 에어 블로우로부터 온도 분포를 해석하므로 사용자는 냉각 채널의 위치를 정확하고 효과적으로 예측할 수 있습니다.

Shot Sleeve Optimization (슬리브 유동 최적화)

고압다이캐스팅에서 슬리브는 금형 속에 용탕을 빠르게 밀어넣는 데 사용됩니다. 일반적으로 슬리브는 수평으로 위치되고, 용탕은 슬리브 상면의 주입구를 통해 부어집니다. 플런저는 금형 반대편에서 슬리브를 통해 금형 안쪽으로 용탕을 밀어 넣게 됩니다. 적절하게 설계된  플런저 이동조건은 슬리브 내부의 공기 혼입을 최소화하고 슬리브에서의 응고를 피하기 위해 가능한 한 빨리 금형에 용탕을 충진하게 설계되어야 합니다. 하지만,  피스톤이 너무 빨리 이동하는 경우, 슬리브 내에서 용탕의 겹침현상이 발생하여 주조품에 공기 갇힘 결함이 나타날 수 있습니다. FLOW-3D는 다이캐스팅 해석시 플런저 이동에 따른 슬리브 내부의 유동을 실제와 동일하게 반영하여 이와 같은 기포 결함을 최소화할 수 있습니다.

Filling Simulations (충진해석)

고압 다이 캐스팅을 해석할 때, 가장 어려운 과제는 고압 및 고속으로 금형에 충진되는 용탕의 유동을 정확하게 추적하는 것입니다. 많은 주조해석 소프트웨어에서 용탕의 분사와 비산을 정확하게 모사하지 못하는 것이 제품의 결함 예측에 가장 큰 장애물이됩니다. FLOW-3D의 TruVOF™ method는 설계 엔지니어들이 금형내부에서 최적의 유동 패턴을 유도하기 위해 게이트의 위치를 확인하고, 오버 플로우의 위치를 확인하는데 핵심적인 역할을 할 수 있습니다.

FLOW-3D는 엔지니어로 하여금 최종 제품의 품질에 영향을 미칠 수 있는 내부 기공(porosity)의 발생을 알수 있도록 합니다. FLOW-3D는 2원계합금(binary alloy)의 편석(segregation)을 해석할 수 있습니다. 해석에 의한 온도 이력은 냉금(chill)  또는 냉각라인(cooling line)이 추가되거나 수정 될 필요가 있는지, 초기 용탕 온도를 변경해야 하는지 등을 결정하는데 도움을 줍니다. FLOW-3D는 내부 미세수축공의 형성, 열응력 및 2원계합금의 편석을 예측할 수 있습니다.
