Output variables(출력 변수)

FLOW-3D에서 주어진 시뮬레이션의 정확한 출력은 어떤 물리적 모델, 출력 위젯에 정의된 추가 출력 및 특정 구성 요소별 출력에 따라 달라집니다. 이 문서는 FLOW-3D의 출력에 대해 좀 더 복잡한 출력 변수 중 일부를 참조하는 역할을 합니다.

Distance Traveled by Fluid(유체로 이동 한 거리)

때로는 유체 입자가 이동한 거리가 중요한 경우도 있습니다. FLOW-3D에서 사용자는 모델 설정 ‣ 출력 위젯에서 유체가 이동한 거리에 대한 출력을 요청할 수 있습니다. 이 기능은 유체가 흐름 영역(경계 또는 질량 소스를 통해)에 들어간 시간 또는 유체가 도메인을 통해 이동한 거리를 계산합니다. 이 기능은 모든 시뮬레이션에도 사용할 수 있으며, 특별한 모델을 사용할 필요가 없으며, 흐름에도 영향을 미치지 않습니다. 이 모델을 사용하려면 출력 위젯으로 이동하고 추가 출력 섹션에서 “Distance traveled by fluid” 옆의 체크상자를 선택하십시오.

 노트

추가 출력 섹션은 출력 위젯의 모든 탭에서 사용할 수 있습니다.

유체 도착 시간

유체 도착 시간을 아는 것은 종종 유용합니다. 예를 들어 주조 시뮬레이션에서 주입 시간을 결정하는 데 사용할 수 있습니다. 제어 볼륨은 충전 프로세스 동안 여러 번 채워지고 비워지기 때문에 계산 셀이 채워지는 처음과 마지막 시간 모두 기록되고, 후 처리를 위해 저장될 수 있습니다. 이 작업은 출력 위젯과 추가 출력 섹션 내에서 유체 도착 시간 확인란을 선택하여 수행됩니다.

 노트

이 출력 옵션은 1 유체 자유 표면 흐름에만 사용할 수 있습니다.

유체 체류 시간

때로는 유체가 계산 영역 내에서 보내는 시간인 체류시간을 아는 것이 유용합니다. 이는 출력 ‣ Output ‣ Additional Output ‣ Fluid residence time 확인란을 선택하여 수행합니다. 여기서 S로 지정된 이 변수에 대한 전송 방정식은 단위 소스 항과 함께 Solve됩니다.

유체 체류 시간(Fluid residence time)
유체 체류 시간(Fluid residence time)

여기에서 t는 시간이며 u는 유체 속도입니다.

S의 단위는 시간이다. 계산 도메인에 들어가는 모든 유체에 대한 S의 초기값은 0입니다.

의 값은 항상 second order체계를 가진 데이터로부터 근사치를 구합니다.

이 출력 옵션은 1 유체 및 2 유체 유량 모두에 사용할 수 있습니다.

 노트

경계 조건 또는 소스에서 도메인으로 유입되는 유체가 이미 도메인에 있는 유체와 혼합될 때 체류가 감소하는 것처럼 보일 수 있습니다.

Wall Contact Time

벽면 접촉 시간 출력은 (1)개별 유체 요소가 특정 구성 요소와 접촉하는 시간 및 (2)특정 구성 요소가 유체와 접촉하는 시간을 추적합니다. 이 모델은 액체 금속이 모래 오염물과 접촉했을 때 오염과 상관 관계가 있는 proxy 변수를 제공하기 위한 것입니다. 이 출력은 최종 주조물에서 오염된 유체가 어디에 있는지 확인하는 데 사용될 수 있습니다. 접촉 시간 모델의 또 다른 해석은, 예를 들어, 용해를 통해 다소 일정한 비율로 화학물질을 방출하는 물에 잠긴 물체에 의한 강의 물의 오염입니다.

모델은 Model Setup ‣ Output ‣ Wall contact time 박스를 확인하여 활성화됩니다. 또한 Model Setup ‣ Output ‣ Geometry Data section의 각 구성요소에 대해 해당 구성요소를 계산에 포함하기 위해 반드시 설정해야 하는 Contact time flag가 있습니다.

이 모델은 실제 구성 요소, 즉 고체, 다공성 매체, 코어 가스 및 충전 퇴적물 구성 요소로 제한됩니다. 접촉 시간은 유체 # 1과 관련해서만 계산됩니다.

Model Setup ‣ Output ‣ Geometry Data ‣ Forces 옵션을 활성화하면 부품에 대한 압력, 전단력, 탄성 및 벽 접착력을 History Data에 출력할 수 있습니다.

압력을 가지지 않은 셀(즉, 도메인 외부에 있거나 다른 구성 요소 안에 있는 셀)이 구성 요소 주변의 각 셀에 대한 압력 영역 제품을 합산하는 동안 어떻게 처리되는지를 제어하는 압력 계산에 대한 몇 가지 추가 옵션이 있습니다. 기본 동작은 이러한 셀에서 사용자 정의 기준 압력을 사용하는 것입니다. 지정되지 않은 경우 기준 압력은 초기 무효 압력인 PVOID로 기본 설정됩니다. 또는, 코드는 Reference pressure is code calculated 옵션을 선택하여 구성요소의 노출된 표면에 대한 평균 압력을 사용할 수 있습니다.

마지막으로, 일반 이동 물체의 경우, 규정된/제약을 받는 대로 물체를 이동시키는 힘을 나타내는 잔류 힘의 추가 출력이 있습니다.

Torques

Model Setup ‣ Output ‣ Force 옵션이 활성화되면 구성 요소의 토크가 계산되고 History Data에 출력됩니다. 토크는 힘-모멘트에 대한 기준점 X, 힘-모멘트에 대한 기준점 Y, 정지 구성 요소에 대한 힘-모멘트 입력에 대한 기준점 Z에 의해 지정된 지점에 대해 보고됩니다. 참조점의 기본 위치는 원점입니다.

General Moving Objects에는 몇 가지 추가 참고 사항이 있습니다. 첫째, 토크는 (1) 6-DOF 동작의 질량 위치 중심 또는 (2)고정축 및 고정점 회전의 회전 축/점에 대해 보고됩니다. 힘에서 행해지는 것과 마찬가지로, 규정된/제한된 바와 같이 물체를 이동시키는 토크를 나타내는 잔류 토크의 출력도 있습니다.

 노트

힘 및 토크 출력은 각 지오메트리 구성 요소의 일반 히스토리 데이터에 기록됩니다. 출력은 개별 힘/토크 기여 (예: 압력, 전단, 탄성, 벽 접착) 및 개별 기여도의 합으로 계산된 총 결합력/토크로 제공됩니다.

Hydraulic Data

깊이 기준 유압 데이터를 요청하려면 출력 ‣ 고급으로 이동한 후 유압 데이터 옆의 확인란을 선택하십시오(심층 평균 값과 중력을 -Z 방향으로 가정).

이 옵션은 FLOW-3D가 유압 시뮬레이션에 유용할 수 있는 추가 깊이 평균 데이터를 출력하도록 합니다.

  • Flow depth
  • Maximum flow depth
  • Free surface elevation
  • Velocity
  • Offset velocity
  • Froude number
  • Specific hydraulic head
  • Total hydraulic head

이 수량 각각에 대해 하나의 값 이 메쉬의 모든 (x, y) 위치에서 계산되고 수직 열의 모든 셀에 저장됩니다 (이 수량이 깊이 평균이기 때문에 z 방향으로 데이터의 변화가 없습니다). 변수는 정확도를 보장하기 위해주기마다 계산됩니다. 모든 경우에,  깊이 평균 속도, z- 방향  의 중력 가속도, 유체 깊이, 및 컬럼 내 유체의 최소 z- 좌표입니다.

  • 유압 헤드 계산은 스트림 라인이 평행하다고 가정한다는 점을 유념해야 합니다. 예를 들어 플럭스 표면이 재순환 흐름 영역에 배치되는 경우 이 문제가 발생할 수 있습니다. 이 경우, 유량 표면에서 보고된 유량 평균 유압 헤드는 헤드의 계산에서 흐름 방향이 무시되기 때문에 예상보다 클 수 있습니다.

Total Hydraulic Head 3D(총 유압 헤드 3D)

또한 총 유압 헤드 3D 옵션을 확인하여 국부적(3D) 속도 필드, 플럭스 표면에서의 유압 에너지(배플 참조) 및 플럭스 기반 유압 헤드를 사용하여 유체 1의 총 헤드를 계산할 수 있다. 3D 계산은 국부 압력을 사용하여 수행되며(즉, 압력이 유체 깊이와 관련이 있다고 가정하지 않음) 원통 좌표와 호환됩니다.

 노트

  • 유압 헤드 계산은 스트림 라인이 평행하다고 가정한다는 점을 유념해야 한다. 예를 들어 플럭스 표면이 재순환 흐름 영역에 배치되는 경우 문제가 발생할 수 있습니다. 이 경우, 플럭스 표면에서 보고된 유량 평균 유압 헤드는 헤드의 계산 시 흐름 방향이 무시되기 때문에 예상보다 클 수 있습니다.

이 경우 플럭스 표면에 보고된 플럭스 평균 유압 헤드는 헤드 계산 시 흐름 방향이 무시되므로 예상보다 클 수 있습니다.

FLOW-3D에는 History Probes, Flux surface, Sampling Volumes의 세 가지 주요 측정 장치가 있습니다. 이러한 장치를 시뮬레이션에 추가하는 방법은 모델 설정 섹션에 설명되어 있습니다(측정 장치 참조). 이들의 출력은 기록 데이터 편집 시간 간격으로 flsgrf 파일의 일반 기록 데이터 카탈로그에 저장됩니다. 이러한 결과는 Analyze ‣ Probe 탭에서 Probe Plots을 생성하여 액세스할 수 있습니다.

히스토리 프로브 출력

히스토리 프로브를 생성하는 단계는 모델 설정 섹션에 설명되어 있습니다(기록 프로브 참조). 시뮬레이션에 사용된 물리 모델에 따라 각각의 History Probe에서 서로 다른 출력을 사용할 수 있습니다. 프로브를 FSI/TSE로 지정하면 유한 요소 메시 안에 들어가야 하는 위치에서 응력/스트레인 데이터만 제공한다. 유체 프로브가 솔리드 형상 구성 요소에 의해 차단된 영역 내에 위치하는 경우, 기하학적 구조와 관련된 수량(예: 벽 온도)만 계산된다. 일반적으로 프로브 좌표에 의해 정의된 위치에서 이러한 양을 계산하려면 보간이 필요하다.

플럭스 표면 출력

플럭스 표면은 이를 통과하는 수량의 흐름을 측정하는데 사용되는 특별한 물체입니다. 플럭스 표면을 만드는 단계는 모델 설정 섹션에 설명되어 있습니다(플럭스 표면 참조). 각 플럭스 표면에 대해 계산된 수량은 다음과 같습니다.

  • Volume flow rate for fluid #1
  • Volume flow rate for fluid #2 (for two-fluid problems only)
  • Combined volume flow rate (for two-fluid problems only)
  • Total mass flow rate

  • 플럭스 표면은 각 표면의 유량과 입자 수가 정확하도록 그들 사이에 적어도 두 개의 메쉬 셀이 있어야 합니다.
  • 유압 데이터 및 총 유압 헤드 3D 옵션을 사용할 때는 유압 헤드 계산이 스트림 라인이 평행하다고 가정한다는 점을 유념해야 한다. 예를 들어 플럭스 표면이 재순환 흐름 영역에 배치되는 경우 이 문제가 발생할 수 있습니다. 이 경우, 유량 표면에서 보고된 유량 평균 유압 헤드는 헤드의 계산에서 흐름 방향이 무시되기 때문에 예상보다 클 수 있습니다.

SYNOPSIS

본 논문에서는 현재 환기 시스템의 성능을 검사하고 개선하여 COSHH 규정 요건을 1개 충족한다는 관점에서 작업장 내 공기 흐름 시뮬레이션에 CFO(Computational Fluid Dynamics) 기법을 적용하는 방법을 제시하고 설명합니다. 예측된 공기 흐름 패턴과 세 CFD 코드가 작업장 내의 선택된 지점에서 측정한 공기의 분배를 비교한 결과, 일반적으로 일치된 것으로 나타났으며, 기존 환기 시스템의 성능이 오염물질의 제거 가능성에 대해 불만족스러운지 확인합니다. CFD 기법을 사용하여 작업장 환기 및 오염 문제에 대한 실용적인 솔루션을 식별할 수 있었습니다.

INTRODUCTION

산업 공장에서 환기 시스템을 갖추는 목적은 열적 쾌적성을 촉진하고 유해 오염 물질에 대한 작업자의 잠재적 노출을 방지하는 것입니다. 작업장 내 근로자에게 미치는 건강상의 영향을 위해 보건 및 안전 행정부는 광범위한 산업 물질에 대한 단기 및 장기 노출에 대한 직업상 노출 제한(1) 목록을 발행합니다.

본사의 보건 물리학 부서에서 일상적으로 실시하는 현장 테스트*는 대기 오염물질의 높은 수위가 COSHH 법에 따라 요구되는 작업 한계를 초과함을 나타냅니다. 당사는 COSHH 규정에서 요구하는 대로 작업 수준 내에서 공기 오염 농도 수준을 가져오기 위해 작업장 내의 공기 흐름에 대한 광범위한 조사를 수행하도록 회사로부터 의뢰 받았습니다.

작업장 내의 공기 흐름 패턴이 상당히 복잡하다는 것을 알게 되었고, 원하는 공기 품질 개선을 달성하기 위해 실내 공기 이동에 대한 측정, 연기 흐름 시각화 및 컴퓨터 모델링을 수행할 필요가 있는 것으로 판단되었습니다.

우리의 목표는 현재의 환기 시스템을 평가하면서 이러한 방법을 간략히 보고하고 B에 워크샵 내의 오염이라는 ait의 수준을 감소시킬 수 있는 실용적인 솔루션을 제안하며, 3개의 CFO 프로그램과의 아웃·측정 및 계산 간의 합의를 평가하는 것입니다.

최근, 건물의 공기 흐름 패턴을 예측하기 위해 계산 유체 역학(CFD)의 사용에 대한 관심이 증가하고 있습니다. CFD 기법의 적용 범위를 나타내기 위해 그러한 몇 가지 예가 보고되었습니다(2) * 프로젝트의 기밀성 때문에 해당 회사의 이름을 지정할 수 없습니다.

DESCRIPTION OF THE WORKSHOP AND ITS
VENTILATION SYSTEM

작업장 및 환기 시스템에 대한 설명 메인 룸은 9m 길이 x 7 m폭 및 4.5m 높이의 주요 치수를 가진 작업장 단지의 일부입니다. 그리고 ante-room은 8m 길이 x 2m폭 x 2.5m 높이 크기를 가지고 있습니다. 아주 높아요. 여기에는 각 제어 장치와 동일한 세 가지 시설, 선반 부스, 드릴 부스, 페틀링 부스, 지역 배기 후드 및 다수의 작업 벤치가 포함되어 있습니다(그림 참조).

실내 환기 시스템은 레지스터 및 기타 개구부를 통한 공급과 추출물로 구성됩니다. 추출 측면은 앞서 언급한 세 개의 부스에 추가 추출이 있는 세 개의 용해로 위의 세 개의 국부 배기 후드와 벽면에 위치한 두 개의 일반 실내 추출물로 구성됩니다.

DISCUSSION OF RESULTS FROM MEASUREMENTS
AND SMOKE FLOW VISUALISATION

입력 측면은 메인 입구 도어(도어 B)의 개구부에서 유입되는 입력 공기가 추가된 6개의 공급 레지스터와 인접 룸을 연결하는 도어(도어 A)에 위치한 또 다른 개방으로 구성됩니다. 작업장에서 수행한 측정은 공기 흐름 패턴, 공기 온도, 속도, 인클로저 표면 온도, 입구 및 출구 공기 온도와 관련이 있습니다.

DISCUSSION OF RESULTS FROM MEASUREMENTS
AND SMOKE FLOW VISUALISATION

작업장 내의 다양한 위치에서 측정된 속도 및 압력 측정과 연기 흐름 시각화 결과, 공급 레지스터의 흡입 유량 기여도가 도어 개구부 A 및 B의 기여율보다 상당히 낮고 시간당 10회의 공기 변화라는 기계적 환기 속도보다 낮았습니다.

A.E.C.P. (3) 및 C.I.B.S.E. (4) 가이드에 의해 종료됩니다. 원칙적으로, 그러한 차이는 중요하지 않을 것입니다. 그러나 이 경우 도어 개구부에서 유입되는 공기에는 이미 오염 물질이 포함되어 있어 작업장의 오염 수준이 증가할 수 있습니다.

따라서 총 흡입 유량의 80-90% 순서로 공급 레지스터를 통과하는 공급 공기의 비율이 더 높은 것이 바람직합니다. 또한 6개의 공급 레지스터 중 하나, 다수의 로컬 추출 후드 및 2개의 일반 객실 추출물을 재설계하거나 상당한 업그레이드가 필요한 것으로 확인되었습니다.

요약하자면, 공기 흐름 측정 및 연기 흐름 시각화는 작업장 내의 공기 흐름 패턴이 두 개의 큰 흐름 영역에 의해 지배된다는 것을 나타냅니다.

작업 수준의 영역 1은 도어 A 및 B의 개구부에서 나오는 강한 에어 제트에 의해 지배되고, 다른 영역은 작업장 상층에 위치한 약한 재순환의 넓은 영역에 의해 지배됩니다.

작은 방과 관련하여, 일부 연기가 그 지역에 도달한 것으로 관측되었지만, 일단 그곳에 도달한 후에는 상당한 시간 동안 남아 있었습니다.

COMPUTER MODELLING OF AIRFLOW

측정 및 연기 흐름 시각화를 통해 작업장 내의 공기 흐름은 매우 복잡하고 3차원적이라는 것을 알 수 있었습니다. 따라서 연기 흐름 시각화 및 제한된 수의 국소 기류 측정만을 기반으로 오염 문제에 대한 해결책을 제안하는 것은 많은 중요한 흐름 특징을 간과할 수 있기 때문에 신중하지 못할 것으로 판단되었습니다.

따라서 이 문제를 조사하기 위해 긍정적인 조치를 취하기로 결정되었습니다. 이는 CFD(Computational Fluid Dynamic) 기법을 활용하여 작업장 내에 현재 존재하는 공기 흐름을 초기에 시뮬레이션한 후 가능한 변경의 영향을 조사하기 위해 구성되었습니다.

컴퓨터 시뮬레이션은 처음에는 HARWELL FLOW-3D 소프트웨어를 사용하여 HARWELL CRAY-2 슈퍼 컴퓨터 시스템에서 수행되었습니다. 작업장의 공기 흐름, 온도 및 오염 분포에 대한 계산 결과가 최근 저자 중 한 명이 제시되었으며 다음과 같은 결과를 나타냈습니다. (이하 일부 내용 생략… 자세한 내용은 하단부의 원문 참조 바랍니다.)

Gravitational and sedimentation microfluidic technique (Huh et al. Anal Chem 2007)의 중력 회로도를 사용한 입자 분류

중력을 사용한 미세 유체 입자 분류

Microfluidics Particle Sorting Using Gravity

미세 유체 입자 분류는 진단, 화학적 및 생물학적 분석, 식품 및 화학 처리, 환경 평가에 적용됩니다. 이전 블로그에서 유체 역학을 사용한 미세 유체 입자 분류에 대해 이야기했습니다 . 같은 주제를 바탕으로 중력을 사용하여 미세 입자를 분류하는 또 다른 방법에 대해 논의하겠습니다. 아래 애니메이션에서 볼 수 있습니다.

유비쿼터스 중력(Ubiquitous gravity)은 미세 유체 장치에서 미세 입자를 분류하는 데 사용할 수 있습니다. 중력이 입자의 움직임에 수직으로 작용할 때 입자는 반경에 따른 속도로 안정됩니다. 또한 입자의 운동은 입자의 밀도, 유체의 밀도 및 유체의 점도 사이의 차이에서 비롯된 유체 역학적 효과의 영향을받습니다. 아래 이미지는 중력 분류 기술 회로도를 보여줍니다.

부력 대 항력

앞서 언급했듯이 중력은 서로 다른 입자가 서로 다른 속도로 침전되도록합니다. 모든 입자의 밀도가 같고 입자 밀도가 주변 유체의 밀도보다 낮 으면 부력 우세와 항력 우세라는 두 가지 유형의 분류를 사용할 수 있습니다. 반경이 더 큰 입자는 더 많은 부력을 경험하고 작은 입자 위의 경로를 따르는 경향이 있습니다. 그러나 외장 액체 (입자를 운반하는 용액)의 유입 속도가 충분히 높으면 항력 효과가 우세하기 시작하고 더 큰 입자가 더 작은 입자의 경로 아래로 이동하는 경향이 있습니다.

FLOW-3D 시뮬레이션 결과

경쟁하는 부력과 항력은 아래 FLOW-3D 에서 얻은 시뮬레이션 결과에서 명확하게 볼 수 있습니다 . 그림 1은 부력 지배적 인 입자 분류의 경우를 보여줍니다. 더 큰 (빨간색) 입자는 수평 채널의 상단을 향해 정렬됩니다. Fig. 2에 나타난 결과는 부력이 우세한 경우의 유입 초 속도를 20 배로 설정 한 후 얻은 것이다. 더 높은 입구 속도에서 더 큰 입자는 더 많은 운동량을 전달하므로 그 위치는 수직 부력의 영향을받지 않습니다. 따라서 입자는 수평 채널의 상단으로 올라가지 않습니다. 대신 그들은 계속해서 바닥으로 이동합니다.

ABSTRACT

나노 빌딩 블록의 직접 조립은 고유 한 특성을 가진 복잡한 나노 구조를 생성하는 다양한 경로를 제공합니다. 나노 입자의 상향식 조립은 이러한 기능적이고 새로운 나노 구조를 제작하는 가장 좋은 방법 중 하나로 간주되었습니다.

그러나 결정질, 고체 및 균질 나노 구조를 만드는 데 대한 연구가 부족합니다. 이를 위해서는 나노 입자의 조립을 유도하는 힘에 대한 근본적인 이해와 원하는 나노 구조의 형성을 가능하게하는 이러한 힘의 정밀한 제어가 필요합니다. 여기에서, 우리는 콜로이드 나노 입자가 외부에서 적용된 전기장을 사용하여 단일 단계로 조립되고 동시에 3D 고체 나노 구조로 융합 될 수 있음을 보여줍니다.

다양한 조립 매개 변수의 영향을 이해함으로써, 우리는 1 분 이내에 25nm의 작은 피처 크기를 가진 나노 기둥, 나노 박스 및 나노 링과 같은 복잡한 형상을 가진 3D 금속 재료의 제조를 보여주었습니다.

결정질, 고체 및 균질 나노 구조를 제조하는 연구는 부족합니다. 이것은 주로 NP의 조립 및 원하는 형상으로의 융합을 제어하는 ​​데 어려움이 있기 때문입니다. 입자 구성, 기능화 및 크기에 따라 NP의 조립 및 융합을 제어하는 ​​힘과 에너지가 다를 수 있습니다. 예를 들어, 현탁 매체를 기반으로하여 NP는 표면 에너지 및 전하와 같은 다른 표면 특성을 가질 수 있으며, 이는 조립 공정 및 기판과의 NP 상호 작용에 영향을 줄 수 있습니다 .

마찬가지로 더 큰 크기의 NP는 작은 것은 단단한 구조로 융합하기 어렵습니다. 원하는 재료와 기하학적 구조로 나노 구조를 성공적으로 제작하려면 조립 공정에 관련된 힘을 제어하는 ​​지배적 인 매개 변수를 식별하는 것이 중요합니다. 이 연구에서 우리는 다양한 금속 NP의 조립 및 융합을 가능하게하는 직접 조립 기술을 개발하여 표면에 고도로 조직화 된 3D 결정질, 고체 나노 구조를 제작했습니다.

Free Surface Modeling Methods

An interface between a gas and liquid is often referred to as a free surface. The reason for the “free” designation arises from the large difference in the densities of the gas and liquid (e.g., the ratio of density for water to air is 1000). A low gas density means that its inertia can generally be ignored compared to that of the liquid. In this sense the liquid moves independently, or freely, with respect to the gas. The only influence of the gas is the pressure it exerts on the liquid surface. In other words, the gas-liquid surface is not constrained, but free.

자유 표면 모델링 방법

기체와 액체 사이의 계면은 종종 자유 표면이라고합니다.  ‘자유’라는 호칭이 된 것은 기체와 액체의 밀도가 크게 다르기 때문입니다 (예를 들어, 물 공기에 대한 밀도 비는 1000입니다).  기체의 밀도가 낮다는 것은 액체의 관성에 비해 기체의 관성은 일반적으로 무시할 수 있다는 것을 의미합니다.  이러한 의미에서, 액체는 기체에 대해 독립적으로, 즉 자유롭게 움직입니다.  기체의 유일한 효과는 액체의 표면에 대한 압력입니다.  즉, 기체와 액체의 표면은 제약되어있는 것이 아니라 자유롭다는 것입니다.

In heat-transfer texts the term ‘Stephen Problem’ is often used to describe free boundary problems. In this case, however, the boundaries are phase boundaries, e.g., the boundary between ice and water that changes in response to the heat supplied from convective fluid currents.

열전달에 관한 문서는 자유 경계 문제를 묘사할 때 “Stephen Problem’”라는 용어가 자주 사용됩니다.  그러나 여기에서 경계는 상(phase) 경계, 즉 대류적인 유체의 흐름에 의해 공급된 열에 반응하여 변화하는 얼음과 물 사이의 경계 등을 말합니다.

Whatever the name, it should be obvious that the presence of a free or moving boundary introduces serious complications for any type of analysis. For all but the simplest of problems, it is necessary to resort to numerical solutions. Even then, free surfaces require the introduction of special methods to define their location, their movement, and their influence on a flow.

이름이 무엇이든, 자유 또는 이동 경계가 존재한다는 것은 어떤 유형의 분석에도 복잡한 문제를 야기한다는 것은 분명합니다. 가장 간단한 문제를 제외한 모든 문제에 대해서는 수치 해석에 의존할 필요가 있습니다. 그 경우에도 자유 표면은 위치, 이동 및 흐름에 미치는 영향을 정의하기 위한 특별한 방법이 필요합니다.

In the following discussion we will briefly review the types of numerical approaches that have been used to model free surfaces, indicating the advantages and disadvantages of each method. Regardless of the method employed, there are three essential features needed to properly model free surfaces:

  1. A scheme is needed to describe the shape and location of a surface,
  2. An algorithm is required to evolve the shape and location with time, and
  3. Free-surface boundary conditions must be applied at the surface.

다음 설명에서는 자유 표면 모델링에 사용되어 온 다양한 유형의 수치적 접근에 대해 간략하게 검토하고 각 방법의 장단점을 설명합니다. 어떤 방법을 사용하는지에 관계없이 자유롭게 표면을 적절히 모델화하는 다음의 3 가지 기능이 필요합니다.

  1. 표면의 형상과 위치를 설명하는 방식
  2. 시간에 따라 모양과 위치를 업데이트 하는 알고리즘
  3. 표면에 적용할 자유 표면 경계 조건

Lagrangian Grid Methods

Conceptually, the simplest means of defining and tracking a free surface is to construct a Lagrangian grid that is imbedded in and moves with the fluid. Many finite-element methods use this approach. Because the grid and fluid move together, the grid automatically tracks free surfaces.

라그랑주 격자 법

개념적으로 자유 표면을 정의하고 추적하는 가장 간단한 방법은 유체와 함께 이동하는 라그랑주 격자를 구성하는 것입니다. 많은 유한 요소 방법이 이 접근 방식을 사용합니다. 격자와 유체가 함께 움직이기 때문에 격자는 자동으로 자유 표면을 추적합니다.

At a surface it is necessary to modify the approximating equations to include the proper boundary conditions and to account for the fact that fluid exists only on one side of the boundary. If this is not done, asymmetries develop that eventually destroy the accuracy of a simulation.

표면에서 적절한 경계 조건을 포함하고 유체가 경계의 한면에만 존재한다는 사실을 설명하기 위해 근사 방정식을 수정해야합니다. 이것이 수행되지 않으면 결국 시뮬레이션의 정확도를 훼손하는 비대칭이 발생합니다.

The principal limitation of Lagrangian methods is that they cannot track surfaces that break apart or intersect. Even large amplitude surface motions can be difficult to track without introducing regridding techniques such as the Arbitrary-Lagrangian-Eulerian (ALE) method. References 1970 and 1974 may be consulted for early examples of these approaches.

라그랑지안 방법의 주요 제한은 분리되거나 교차하는 표면을 추적 할 수 없다는 것입니다. ALE (Arbitrary-Lagrangian-Eulerian) 방법과 같은 격자 재생성 기법을 도입하지 않으면 진폭이 큰 표면 움직임도 추적하기 어려울 수 있습니다. 이러한 접근법의 초기 예를 보려면 참고 문헌 1970 및 1974를 참조하십시오.

The remaining free-surface methods discussed here use a fixed, Eulerian grid as the basis for computations so that more complicated surface motions may be treated.

여기에서 논의된 나머지 자유 표면 방법은 보다 복잡한 표면 움직임을 처리할 수 있도록 고정된 오일러 그리드를 계산의 기준으로 사용합니다.

Surface Height Method

Low amplitude sloshing, shallow water waves, and other free-surface motions in which the surface does not deviate too far from horizontal, can be described by the height, H, of the surface relative to some reference elevation. Time evolution of the height is governed by the kinematic equation, where (u,v,w) are fluid velocities in the (x,y,z) directions. This equation is a mathematical expression of the fact that the surface must move with the fluid:

표면 높이 법

낮은 진폭의 슬로 싱, 얕은 물결 및 표면이 수평에서 너무 멀리 벗어나지 않는 기타 자유 표면 운동은 일부 기준 고도에 대한 표면의 높이 H로 설명 할 수 있습니다. 높이의 시간 진화는 운동학 방정식에 의해 제어되며, 여기서 (u, v, w)는 (x, y, z) 방향의 유체 속도입니다. 이 방정식은 표면이 유체와 함께 움직여야한다는 사실을 수학적으로 표현한 것입니다.

Finite-difference approximations to this equation are easy to implement. Further, only the height values at a set of horizontal locations must be recorded so the memory requirements for a three-dimensional numerical solution are extremely small. Finally, the application of free-surface boundary conditions is also simplified by the condition on the surface that it remains nearly horizontal. Examples of this technique can be found in References 1971 and 1975.

이 방정식의 유한 차분 근사를 쉽게 실행할 수 있습니다.  또한 3 차원 수치 해법의 메모리 요구 사항이 극도로 작아지도록 같은 높이의 위치 값만을 기록해야합니다.  마지막으로 자유 표면 경계 조건의 적용도 거의 수평을 유지하는 표면의 조건에 의해 간소화됩니다.  이 방법의 예는 참고 문헌의 1971 및 1975을 참조하십시오.

Marker-and-Cell (MAC) Method

The earliest numerical method devised for time-dependent, free-surface, flow problems was the Marker-and-Cell (MAC) method (see Ref. 1965). This scheme is based on a fixed, Eulerian grid of control volumes. The location of fluid within the grid is determined by a set of marker particles that move with the fluid, but otherwise have no volume, mass or other properties.

MAC 방법

시간 의존성을 가지는 자유 표면 흐름의 문제에 대해 처음 고안된 수치 법이 MAC (Marker-and-Cell) 법입니다 (참고 문헌 1965 참조).  이 구조는 컨트롤 볼륨 고정 오일러 격자를 기반으로합니다.  격자 내의 유체의 위치는 유체와 함께 움직이고, 그 이외는 부피, 질량, 기타 특성을 갖지 않는 일련의 마커 입자에 의해 결정됩니다.

Grid cells containing markers are considered occupied by fluid, while those without markers are empty (or void). A free surface is defined to exist in any grid cell that contains particles and that also has at least one neighboring grid cell that is void. The location and orientation of the surface within the cell was not part of the original MAC method.

마커를 포함한 격자 셀은 유체로 채워져있는 것으로 간주되며 마커가 없는 격자 셀은 빈(무효)것입니다.  입자를 포함하고, 적어도 하나의 인접 격자 셀이 무효인 격자의 자유 표면은 존재하는 것으로 정의됩니다.  셀 표면의 위치와 방향은 원래의 MAC 법에 포함되지 않았습니다.

Evolution of surfaces was computed by moving the markers with locally interpolated fluid velocities. Some special treatments were required to define the fluid properties in newly filled grid cells and to cancel values in cells that are emptied.

표면의 발전(개선)은 국소적으로 보간된 유체 속도로 마커를 이동하여 계산되었습니다.  새롭게 충전된 격자 셀의 유체 특성을 정의하거나 비어있는 셀의 값을 취소하거나 하려면 특별한 처리가 필요했습니다.

The application of free-surface boundary conditions consisted of assigning the gas pressure to all surface cells. Also, velocity components were assigned to all locations on or immediately outside the surface in such a way as to approximate conditions of incompressibility and zero-surface shear stress.

자유 표면 경계 조건의 적용은 모든 표면 셀에 가스 압력을 할당하는 것으로 구성되었습니다. 또한 속도 성분은 비압축성 및 제로 표면 전단 응력의 조건을 근사화하는 방식으로 표면 위 또는 외부의 모든 위치에 할당되었습니다.

The extraordinary success of the MAC method in solving a wide range of complicated free-surface flow problems is well documented in numerous publications. One reason for this success is that the markers do not track surfaces directly, but instead track fluid volumes. Surfaces are simply the boundaries of the volumes, and in this sense surfaces may appear, merge or disappear as volumes break apart or coalesce.

폭넓게 복잡한 자유 표면 흐름 문제 해결에 MAC 법이 놀라운 성공을 거두고 있는 것은 수많은 문헌에서 충분히 입증되고 있습니다.  이 성공 이유 중 하나는 마커가 표면을 직접 추적하는 것이 아니라 유체의 체적을 추적하는 것입니다.  표면은 체적의 경계에 불과하며, 그러한 의미에서 표면은 분할 또는 합체된 부피로 출현(appear), 병합, 소멸 할 가능성이 있습니다.

A variety of improvements have contributed to an increase in the accuracy and applicability of the original MAC method. For example, applying gas pressures at interpolated surface locations within cells improves the accuracy in problems driven by hydrostatic forces, while the inclusion of surface tension forces extends the method to a wider class of problems (see Refs. 1969, 1975).

다양한 개선으로 인해 원래 MAC 방법의 정확성과 적용 가능성이 증가했습니다. 예를 들어, 셀 내 보간 된 표면 위치에 가스 압력을 적용하면 정 수력으로 인한 문제의 정확도가 향상되는 반면 표면 장력의 포함은 방법을 더 광범위한 문제로 확장합니다 (참조 문헌. 1969, 1975).

In spite of its successes, the MAC method has been used primarily for two-dimensional simulations because it requires considerable memory and CPU time to accommodate the necessary number of marker particles. Typically, an average of about 16 markers in each grid cell is needed to ensure an accurate tracking of surfaces undergoing large deformations.

수많은 성공에도 불구하고 MAC 방법은 필요한 수의 마커 입자를 수용하기 위해 상당한 메모리와 CPU 시간이 필요하기 때문에 주로 2 차원 시뮬레이션에 사용되었습니다. 일반적으로 큰 변형을 겪는 표면의 정확한 추적을 보장하려면 각 그리드 셀에 평균 약 16 개의 마커가 필요합니다.

Another limitation of marker particles is that they don’t do a very good job of following flow processes in regions involving converging/diverging flows. Markers are usually interpreted as tracking the centroids of small fluid elements. However, when those fluid elements get pulled into long convoluted strands, the markers may no longer be good indicators of the fluid configuration. This can be seen, for example, at flow stagnation points where markers pile up in one direction, but are drawn apart in a perpendicular direction. If they are pulled apart enough (i.e., further than one grid cell width) unphysical voids may develop in the flow.

마커 입자의 또 다른 한계는 수렴 / 발산 흐름이 포함된 영역에서 흐름 프로세스를 따라가는 작업을 잘 수행하지 못한다는 것입니다. 마커는 일반적으로 작은 유체 요소의 중심을 추적하는 것으로 해석됩니다. 그러나 이러한 유체 요소가 길고 복잡한 가닥으로 당겨지면 마커가 더 이상 유체 구성의 좋은 지표가 될 수 없습니다. 예를 들어 마커가 한 방향으로 쌓여 있지만 수직 방향으로 떨어져 있는 흐름 정체 지점에서 볼 수 있습니다. 충분히 분리되면 (즉, 하나의 그리드 셀 너비 이상) 비 물리적 공극이 흐름에서 발생할 수 있습니다.

Surface Marker Method

One way to limit the memory and CPU time consumption of markers is to keep marker particles only on surfaces and not in the interior of fluid regions. Of course, this removes the volume tracking property of the MAC method and requires additional logic to determine when and how surfaces break apart or coalesce.

표면 마커 법

마커의 메모리 및 CPU 시간의 소비를 제한하는 방법 중 하나는 마커 입자를 유체 영역의 내부가 아니라 표면에만 보존하는 것입니다.  물론 이는 MAC 법의 체적 추적 특성이 배제되기 때문에 표면이 분할 또는 합체하는 방식과 시기를 특정하기위한 논리를 추가해야합니다.

In two dimensions the marker particles on a surface can be arranged in a linear order along the surface. This arrangement introduces several advantages, such as being able to maintain a uniform particle spacing and simplifying the computation of intersections between different surfaces. Surface markers also provide a convenient way to locate the surface within a grid cell for the application of boundary conditions.

2 차원의 경우 표면 마커 입자는 표면을 따라 선형으로 배치 할 수 있습니다.  이 배열은 입자의 간격을 균일하게 유지할 수있는 별도의 표면이 교차하는 부분의 계산이 쉽다는 등 몇 가지 장점이 있습니다.  또한 표면 마커를 사용하여 경계 조건을 적용하면 격자 셀의 표면을 간단한 방법으로 찾을 수 있습니다.

Unfortunately, in three-dimensions there is no simple way to order particles on surfaces, and this leads to a major failing of the surface marker technique. Regions may exist where surfaces are expanding and no markers fill the space. Without markers the configuration of the surface is unknown, consequently there is no way to add markers. Reference 1975 contains examples that show the advantages and limitations of this method.

불행히도 3 차원에서는 표면에 입자를 정렬하는 간단한 방법이 없으며 이로 인해 표면 마커 기술이 크게 실패합니다. 표면이 확장되고 마커가 공간을 채우지 않는 영역이 존재할 수 있습니다. 마커가 없으면 표면의 구성을 알 수 없으므로 마커를 추가 할 방법이 없습니다.
참고 문헌 1975이 방법의 장점과 한계를 보여주는 예제가 포함되어 있습니다.

Volume-of-Fluid (VOF) Method

The last method to be discussed is based on the concept of a fluid volume fraction. The idea for this approach originated as a way to have the powerful volume-tracking feature of the MAC method without its large memory and CPU costs.

VOF (Volume-of-Fluid) 법

마지막으로 설명하는 방법은 유체 부피 분율의 개념을 기반으로합니다. 이 접근 방식에 대한 아이디어는 대용량 메모리 및 CPU 비용없이 MAC 방식의 강력한 볼륨 추적 기능을 갖는 방법에서 시작되었습니다.

Within each grid cell (control volume) it is customary to retain only one value for each flow quantity (e.g., pressure, velocity, temperature, etc.) For this reason it makes little sense to retain more information for locating a free surface. Following this reasoning, the use of a single quantity, the fluid volume fraction in each grid cell, is consistent with the resolution of the other flow quantities.

각 격자 셀 (제어 체적) 내에서 각 유량 (예 : 압력, 속도, 온도 등)에 대해 하나의 값만 유지하는 것이 일반적입니다. 이러한 이유로 자유 표면을 찾기 위해 더 많은 정보를 유지하는 것은 거의 의미가 없습니다. 이러한 추론에 따라 각 격자 셀의 유체 부피 분율인 단일 수량의 사용은 다른 유량의 해상도와 일치합니다.

If we know the amount of fluid in each cell it is possible to locate surfaces, as well as determine surface slopes and surface curvatures. Surfaces are easy to locate because they lie in cells partially filled with fluid or between cells full of fluid and cells that have no fluid.

각 셀 내의 유체의 양을 알고 있는 경우, 표면의 위치 뿐만 아니라  표면 경사와 표면 곡률을 결정하는 것이 가능합니다.  표면은 유체 가 부분 충전 된 셀 또는 유체가 전체에 충전 된 셀과 유체가 전혀없는 셀 사이에 존재하기 때문에 쉽게 찾을 수 있습니다.

Slopes and curvatures are computed by using the fluid volume fractions in neighboring cells. It is essential to remember that the volume fraction should be a step function, i.e., having a value of either one or zero. Knowing this, the volume fractions in neighboring cells can then be used to locate the position of fluid (and its slope and curvature) within a particular cell.

경사와 곡률은 인접 셀의 유체 체적 점유율을 사용하여 계산됩니다.  체적 점유율은 계단 함수(step function)이어야 합니다, 즉, 값이 1 또는 0 인 것을 기억하는 것이 중요합니다.  이 것을 안다면, 인접 셀의 부피 점유율을 사용하여 특정 셀 내의 유체의 위치 (및 그 경사와 곡률)을 찾을 수 있습니다.

Free-surface boundary conditions must be applied as in the MAC method, i.e., assigning the proper gas pressure (plus equivalent surface tension pressure) as well as determining what velocity components outside the surface should be used to satisfy a zero shear-stress condition at the surface. In practice, it is sometimes simpler to assign velocity gradients instead of velocity components at surfaces.

자유 표면 경계 조건을 MAC 법과 동일하게 적용해야 합니다.  즉, 적절한 기체 압력 (및 대응하는 표면 장력)을 할당하고, 또한 표면에서 제로 전단 응력을 충족 시키려면 표면 외부의 어떤 속도 성분을 사용할 필요가 있는지를 확인합니다.  사실, 표면에서의 속도 성분 대신 속도 구배를 지정하는 것이보다 쉬울 수 있습니다.

Finally, to compute the time evolution of surfaces, a technique is needed to move volume fractions through a grid in such a way that the step-function nature of the distribution is retained. The basic kinematic equation for fluid fractions is similar to that for the height-function method, where F is the fraction of fluid function:

마지막으로, 표면의 시간 변화를 계산하려면 분포의 계단 함수의 성질이 유지되는 방법으로 격자를 통과하고 부피 점유율을 이동하는 방법이 필요합니다.  유체 점유율의 기본적인 운동학방정식은 높이 함수(height-function) 법과 유사합니다.  F는 유체 점유율 함수입니다.

A straightforward numerical approximation cannot be used to model this equation because numerical diffusion and dispersion errors destroy the sharp, step-function nature of the F distribution.

이 방정식을 모델링 할 때 간단한 수치 근사는 사용할 수 없습니다.  수치의 확산과 분산 오류는 F 분포의 명확한 계단 함수(step-function)의 성질이 손상되기 때문입니다.

It is easy to accurately model the solution to this equation in one dimension such that the F distribution retains its zero or one values. Imagine fluid is filling a column of cells from bottom to top. At some instant the fluid interface is in the middle region of a cell whose neighbor below is filled and whose neighbor above is empty. The fluid orientation in the neighboring cells means the interface must be located above the bottom of the cell by an amount equal to the fluid fraction in the cell. Then the computation of how much fluid to move into the empty cell above can be modified to first allow the empty region of the surface-containing cell to fill before transmitting fluid on to the next cell.

F 분포가 0 또는 1의 값을 유지하는 같은 1 차원에서이 방정식의 해를 정확하게 모델링하는 것은 간단합니다.  1 열의 셀에 위에서 아래까지 유체가 충전되는 경우를 상상해보십시오.  어느 순간에 액체 계면은 셀의 중간 영역에 있고, 그 아래쪽의 인접 셀은 충전되어 있고, 상단 인접 셀은 비어 있습니다.  인접 셀 내의 유체의 방향은 계면과 셀의 하단과의 거리가 셀 내의 유체 점유율과 같아야 한다는 것을 의미합니다.  그 다음 먼저 표면을 포함하는 셀의 빈 공간을 충전 한 후 다음 셀로 유체를 보내도록 위쪽의 빈 셀에 이동하는 유체의 양의 계산을 변경할 수 있습니다.

In two or three dimensions a similar procedure of using information from neighboring cells can be used, but it is not possible to be as accurate as in the one-dimensional case. The problem with more than one dimension is that an exact determination of the shape and location of the surface cannot be made. Nevertheless, this technique can be made to work well as evidenced by the large number of successful applications that have been completed using the VOF method. References 1975, 1980, and 1981 should be consulted for the original work on this technique.

2 차원과 3 차원에서 인접 셀의 정보를 사용하는 유사한 절차를 사용할 수 있지만, 1 차원의 경우만큼 정확하게 하는 것은 불가능합니다.  2 차원 이상의 경우의 문제는 표면의 모양과 위치를 정확히 알 수없는 것입니다.  그래도 VOF 법을 사용하여 달성 된 다수의 성공 사례에서 알 수 있듯이 이 방법을 잘 작동시킬 수 있습니다.  이 기법에 관한 초기의 연구 내용은 참고 문헌 1975,1980,1981를 참조하십시오.

The VOF method has lived up to its goal of providing a method that is as powerful as the MAC method without the overhead of that method. Its use of volume tracking as opposed to surface-tracking function means that it is robust enough to handle the breakup and coalescence of fluid masses. Further, because it uses a continuous function it does not suffer from the lack of divisibility that discrete particles exhibit.

VOF 법은 MAC 법만큼 강력한 기술을 오버 헤드없이 제공한다는 목표를 달성 해 왔습니다.  표면 추적이 아닌 부피 추적 기능을 사용하는 것은 유체 질량의 분할과 합체를 처리하는 데 충분한 내구성을 가지고 있다는 것을 의미합니다.  또한 연속 함수를 사용하기 때문에 이산된 입자에서 발생하는 숫자를 나눌 수 없는 문제를 겪지 않게 됩니다.

Variable-Density Approximation to the VOF Method

One feature of the VOF method that requires special treatment is the application of boundary conditions. As a surface moves through a grid, the cells containing fluid continually change, which means that the solution region is also changing. At the free boundaries of this changing region the proper free surface stress conditions must also be applied.

VOF 법의 가변 밀도 근사

VOF 법의 특수 처리가 필요한 기능 중 하나는 경계 조건의 적용입니다.  표면이 격자를 통과하여 이동할 때 유체를 포함하는 셀은 끊임없이 변화합니다.  즉, 계산 영역도 변화하고 있다는 것입니다.  이 변화하고있는 영역의 자유 경계에는 적절한 자유 표면 응력 조건도 적용해야합니다.

Updating the flow region and applying boundary conditions is not a trivial task. For this reason some approximations to the VOF method have been used in which flow is computed in both liquid and gas regions. Typically, this is done by treating the flow as a single fluid having a variable density. The F function is used to define the density. An argument is then made that because the flow equations are solved in both liquid and gas regions there is no need to set interfacial boundary conditions.

유체 영역의 업데이트 및 경계 조건의 적용은 중요한 작업입니다.  따라서 액체와 기체의 두 영역에서 흐름이 계산되는 VOF 법에 약간의 근사가 사용되어 왔습니다.  일반적으로 가변 밀도를 가진 단일 유체로 흐름을 처리함으로써 이루어집니다.  밀도를 정의하려면 F 함수를 사용합니다.  그리고, 흐름 방정식은 액체와 기체의 두 영역에서 계산되기 때문에 계면의 경계 조건을 설정할 필요가 없다는 논증이 이루어집니다.

Unfortunately, this approach does not work very well in practice for two reasons. First, the sensitivity of a gas region to pressure changes is generally much greater than that in liquid regions. This makes it difficult to achieve convergence in the coupled pressure-velocity solution. Sometimes very large CPU times are required with this technique.

공교롭게도 이 방법은 두 가지 이유로 인해 실제로는 그다지 잘 작동하지 않습니다.  하나는 압력의 변화에 대한 기체 영역의 감도가 일반적으로 액체 영역보다 훨씬 큰 것입니다.  따라서 압력 – 속도 결합 해법 수렴을 달성하는 것은 어렵습니다.  이 기술은 필요한 CPU 시간이 매우 커질 수 있습니다.

The second, and more significant, reason is associated with the possibility of a tangential velocity discontinuity at interfaces. Because of their different responses to pressure, gas and liquid velocities at an interface are usually quite different. In the Variable-Density model interfaces are moved with an average velocity, but this often leads to unrealistic movement of the interfaces.

두 번째 더 중요한 이유는 계면에서 접선 속도가 불연속이되는 가능성에 관련이 있습니다.  압력에 대한 반응이 다르기 때문에 계면에서 기체와 액체의 속도는 일반적으로 크게 다릅니다.  가변 밀도 모델은 계면은 평균 속도로 동작하지만, 이는 계면의 움직임이 비현실적으로 되는 경우가 많습니다.

Even though the Variable-Density method is sometimes referred to as a VOF method, because is uses a fraction-of-fluid function, this designation is incorrect. For accurately tracking sharp liquid-gas interfaces it is necessary to actually treat the interface as a discontinuity. This means it is necessary to have a technique to define an interface discontinuity, as well as a way to impose the proper boundary conditions at that interface. It is also necessary to use a special numerical method to track interface motions though a grid without destroying its character as a discontinuity.

가변 밀도 방법은 유체 분율 함수를 사용하기 때문에 VOF 방법이라고도하지만 이것은 올바르지 않습니다. 날카로운 액체-가스 인터페이스를 정확하게 추적하려면 인터페이스를 실제로 불연속으로 처리해야합니다. 즉, 인터페이스 불연속성을 정의하는 기술과 해당 인터페이스에서 적절한 경계 조건을 적용하는 방법이 필요합니다. 또한 불연속성으로 특성을 훼손하지 않고 격자를 통해 인터페이스 동작을 추적하기 위해 특수한 수치 방법을 사용해야합니다.

Summary

A brief discussion of the various techniques used to numerically model free surfaces has been given here with some comments about their relative advantages and disadvantages. Readers should not be surprised to learn that there have been numerous variations of these basic techniques proposed over the years. Probably the most successful of the methods is the VOF technique because of its simplicity and robustness. It is this method, with some refinement, that is used in the FLOW-3D program.

여기에서는 자유 표면을 수치적으로 모델링 할 때 사용하는 다양한 방법에 대해 상대적인 장점과 단점에 대한 설명을 포함하여 쉽게 설명하였습니다.  오랜 세월에 걸쳐 이러한 기본적인 방법이 많이 제안되어 온 것을 알고도 독자 여러분은 놀라지 않을 것입니다.  아마도 가장 성과를 거둔 방법은 간결하고 강력한 VOF 법 입니다.  이 방법에 일부 개량을 더한 것이 현재 FLOW-3D 프로그램에서 사용되고 있습니다.

Attempts to improve the VOF method have centered on better, more accurate, ways to move fluid fractions through a grid. Other developments have attempted to apply the method in connection with body-fitted grids and to employ more than one fluid fraction function in order to model more than one fluid component. A discussion of these developments is beyond the scope of this introduction.

VOF 법의 개선은 더 나은, 더 정확한 방법으로 유체 점유율을 격자를 통과하여 이동하는 것에 중점을 두어 왔습니다.  기타 개발은 물체 적합 격자(body-fitted grids) 관련 기법을 적용하거나 여러 유체 성분을 모델링하기 위해 여러 유체 점유율 함수를 채용하기도 했습니다.  이러한 개발에 대한 논의는 여기에서의 설명 범위를 벗어납니다.

Oil & Gas Separators

Oil & Gas Separators

FLOW-3D는 오일 및 물과 같은 혼합 불가능한 유체를 모델링할 수 있으며, 개방된 환경(주변 공기)에 관련된 구성 요소 간의 고유한 인터페이스를 정확하게 추적할 수 있습니다.

전체 영역에 영향을 미치는 역학 관계로 유체가 자유롭게 혼합될 수 있습니다. 시간이 지남에 따라 유체는 연속 위상과 분산 위상 사이의 표류 관계에 따라 다시 분리됩니다.

중력 분리기의 성능은 CFD 모델링을 통해 향상 될 수 있습니다 :

  • Develop vessel inlet configurations to improve uniformity of gas and liquid flows and avoid mixing of oil & water due to wave-induced sloshing
  • Determine the influence of internal equipment on hydraulic efficiency and separation performance
  • Gauge the effects of changes in operating conditions
  • Accurately model small-scale phenomena (multi-phase flows, drops, particles, bubbles)

Magnetic Fields

균일 한 자기장에서 자성 입자는 자화되어 쌍극자-쌍극자 상호 작용으로 인해 사슬 모양의 미세 구조로 조립됩니다. 조립된 체인은 외부 필드의 방향에 맞춰 정렬되는 경향이 있습니다. FLOW-3D를 사용한 이 분석에서는 superparamagnetic beads의 초기 무작위 분포와 베이스에 내장 된 spherical (gold colored) magnetic dipole elements 배열을 포함하는 마이크로 채널을 통해 균일한 필드가 z 방향으로 위쪽으로 적용됩니다. 적용된 필드가있는 경우 비드는 자화되어 개별 체인과 같은 구조로 조립됩니다. 이러한 구조는 고정된 쌍극자 요소에 끌립니다. 분석은 입자 체인의 자체 조립과 내장 된 쌍극자 요소에 체인의 후속 부착을 보여줍니다. 계산 모델은 유체가 입자 운동에 점성 항력을 제공하고 움직이는 입자가 차례로 유체 흐름을 변경하는 완전 결합 입자 유체 상호 작용을 고려합니다. 모델링 결과는 University of Buffalo에서 제공합니다.

( In a uniform magnetic field, magnetic particles become magnetized and assemble into chain-like microstructures due to dipole-dipole interactions. The assembled chains tend to align with the direction of the external field. In this analysis using FLOW-3D, a uniform field is applied upward in the z-direction through a micro-channel that contains an initial random distribution of superparamagnetic beads and an array of spherical (gold colored) magnetic dipole elements embedded in its base. In the presence of an applied field, the beads become magnetized and assemble into discrete chain-like structures.  These structures in turn, are attracted to the anchored dipole elements. The analysis shows the self-assembly of particle chains and the subsequent attachment of the chains onto the embedded dipole elements. The computational model takes into account fully-coupled particle fluid interaction where the fluid provides a viscous drag on particle motion and the moving particles, in turn, alter the fluid flow.

음향학적 입자 초점은 미세 유체 채널의 용액에서 다양한 물체를 제거하는 현대적이고 매우 매력적인 방법입니다. 이 프로세스는 의료 애플리케이션 (악성 세포 제거), 학술 연구 (나노 입자 분리), 산업 애플리케이션 (희토류 재생) 및 환경 애플리케이션 (부유 고형물 격리)에 적용됩니다. 이 기술은 압력 펄스를 사용하여 실질적인 접촉없이 소량의 유체를 이동시키기 때문에 매우 부드러운 프로세스로 간주 될 수 있습니다.

FLOW-3D는 대략적인 분석 솔루션을 사용하는 대신 유동 역학의 결과로 입자에 작용하는 힘을 직접 포착하기 위해 음향 영동 과정을 모델링하는 데 정확하게 사용할 수 있습니다. FLOW-3D에서 이러한 시뮬레이션을 설정하는 것은 특정 주파수에서 음파를 생성 할 수있는 탄성 멤브레인 모델로 인해 간단합니다.

Sediment Transport Model

Sediment Transport Model

Sediment Transport Model

FLOW-3D의 침전물 이송 모델을 사용하여 세굴 및 침전물을 평가할 수 있으며, 여기서 3차원 유량 구성 요소가 세굴 프로세스를 주도하고 있습니다. Flow-3D의 유체역학 모델은 유체물리학을 설명하는 정전기적이지 않은 레이놀즈-평균화된 Navier-Stokes 방정식을 완벽하게 해결합니다. 유체역학적 솔버는 침전물 운반 모듈과 완전히 결합되어 있어 침전물 운반 및 비접착 토양의 부유식 침식, 인포테인먼트 및 침식을 시뮬레이션합니다(Wei et al., 2014). 베드로드, 인포테인먼트 및 정착 프로세스에 사용되는 모든 경험적 관계는 완전히 사용자 정의 가능하며, 최대 10개의 침전물 종(곡물 크기, 질량 밀도, 임계 전단 응력 등 서로 다른 특성을 가진)을 정의할 수 있습니다. FLOW-3D는 짧은 경과 시간 척도에 대한 국부적 스쿠어를 시뮬레이션하는 데 이상적입니다.

FLOW-3D‘s Sediment Transport model can be used to evaluate scour and deposition, where three-dimensional flow components are driving the scouring process. FLOW-3D’s hydrodynamic model solves the full unsteady non-hydrostatic Reynolds-averaged Navier-Stokes equations that describe the flow physics. The hydrodynamic solver is fully coupled with a sediment transport module that simulates bedload and suspended sediment transport, entrainment and erosion for non-cohesive soils (Wei et al., 2014). All empirical relationships used in bedload, entrainment and settling processes are fully customizable, and up to 10 different sediment species (with different properties such as grain size, mass density and critical shear stress) can be defined. FLOW-3D is ideal for simulating local scour over short episodic time scales.

Sediment Transport Model

Sentral Transport 모델은 8.0 버전(Brethour, 2009년)에서 처음 도입되었으며, 11.1 버전(Wei et al., 2014년), 가장 최근에는 12.0 버전(Flow Science, 2019년)에서 광범위한 개정을 거쳤습니다. 숫자 모델에서 시뮬레이션된 물리적 프로세스의 개략도가 아래에 나와 있습니다.

The Sediment Transport model was first introduced in version 8.0 (Brethour, 2009), and has gone through extensive revisions in version 11.1 (Wei et al., 2014), and most recently in version 12.0 (Flow Science, 2019). A schematic of the physical processes simulated in the numerical model is illustrated below.

The different processes modeled by the Sediment Transport Model.

수치 모델에서 침전물은 포장된 Bed로서 일시 중단된 상태로 존재할 수 있습니다. 포장된 Bed는 PRIPT™ 기법을 사용하여 복잡한 솔리드 경계(Hirt 및 Sicilian, 1985)에 표현된 지울 수 없는 솔리드 객체입니다. 이것은 유체역학 용해기의 고체 물체를 나타내는 데 사용되는 방법과 동일합니다. 포장된 Bed의 형태학적 변화는 침전물 질량의 보존에 의해 좌우됩니다.

In the numerical model, sediment can exist as packed bed and in a suspended state. A packed bed is an erodible solid object that is represented using the FAVOR™ technique for complex solid boundaries (Hirt and Sicilian, 1985). This is the same method used to represent solid objects in the hydrodynamic solver. The morphological change in the packed bed is governed by the conservation of sediment mass.

형태학적 변경은 모형에 숫자로 표시되는 여러 가지 물리적 프로세스에 의해 제어됩니다. 이러한 프로세스에는 베드로드 운송, 인포테인먼트 및 증착이 포함됩니다. 베드로드 이송은 침전물이 서스펜션에 전달되지 않고 채널을 따라 횡방향으로 이동하는 물리적 과정입니다. 인포테인먼트란 난류 에디가 패킹 베드 상단의 곡물을 제거하고 일시 중단된 상태로 전환하는 과정입니다. 포장이란 곡물이 현수막에서 안착되어 포장된 침대에 퇴적하는 과정입니다. 수치 모델에서 이것은 일시 중단된 상태에서 포장된 베드 상태로의 전환입니다.

The morphological changes are governed by several different physical processes that are represented numerically in the model. These processes include bedload transport, entrainment and deposition. Bedload transport is the physical process of sediment moving laterally along the channel without being carried into suspension. Entrainment is the process by which turbulent eddies remove the grains from the top of the packed bed and transition to the suspended state. Packing is the process of grains settling out of suspension and depositing onto the packed bed. In the numerical model, this is the transition from the suspended to the packed bed state.

인포테인먼트 및 패킹의 상대적 비율은 포장된 베드와 부유 상태 사이의 침전물 질량 교환을 제어합니다. 이 모델은 Meyer-Peter Müler(1948), Nielsen(1992) 또는 Van Rijn(1984)의 방정식을 사용하여 베드 인터페이스가 포함된 각 메시 셀에서 베드로드 전송을 계산합니다. 메쉬 셀에서 이웃의 각 메쉬 셀로 이동하는 곡물의 양을 결정하기 위해 하위 메쉬 방법이 사용됩니다. 인포테인먼트에서 곡물의 리프팅 속도는 Winterwerp 등(1992)의 방정식을 사용하여 계산됩니다. 안착 속도는 Soulsby(1997년)를 사용하여 계산됩니다. 베드 인터페이스가 포함된 메시 셀에서 인터페이스의 위치, 방향 및 면적을 계산하여 베드 전단 응력, 무차원 전단 응력, 베드로드 전송 속도 및 인포테인먼트 속도를 결정합니다. 3D 난류 흐름의 베드 전단 응력은 표준 벽 함수를 사용하여 중간 곡물 크기에 비례하는 베드 표면 거칠기를 고려하여 평가됩니다.

The relative rates of entrainment and packing control the exchange of sediment mass between the packed bed and suspended states. The model calculates bedload transport in each mesh cell containing the bed interface using the equation of Meyer-Peter Müller (1948), Nielsen (1992) or Van Rijn (1984). A sub-mesh method is employed to determine the amount of grains moving from the mesh cell into each mesh cell in its neighbor. The lifting velocity of grains in entrainment is calculated using the equation of Winterwerp et al. (1992). The settling velocity is calculated using Soulsby (1997). In the mesh cells containing the bed interface, location, orientation and area of the interface are calculated to determine the bed shear stress, dimensionless shear stress, bedload transport rates and entrainment rates. Bed shear stress in 3D turbulent flows is evaluated using the standard wall function with consideration of bed surface roughness that is proportional to the median grain size.

부유된 침전물은 유체의 스칼라 질량 농도로 표시됩니다. 농도는 주어진 셀에서 균일한 것으로 가정되며 유체 셀 밀도 및 점도와 결합됩니다. 각 종에 대해, 부유 침전물 농도는 수송 방정식을 풀어서 계산됩니다.

The suspended sediment is represented as a scalar mass concentration in the fluid. The concentration is assumed to be uniform in a given cell and is coupled with the fluid cell density and viscosity. For each species, the suspended sediment concentration is calculated by solving a transport equation.

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.

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.

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.

FLOW-3D 금속3D프린팅분야 활용

FLOW-3D 레이저 용접분야 활용

금속 3D 프린팅은 적층제조(Additive Manufacturing) 가공법이라고 불리며 일반적으로 금속 파우더 또는 와이어를 한 층씩 적층하여 제조하는 공법이다. 금속 적층제조 공법에 대한 관심은 지난 몇 년 동안 지속적으로 이루어지고 있으며 이와 관련된 연구개발도 활발히 진행되고 있다. 금속 3D 프린팅은 복잡하거나 특수한 형상을 손쉽게 설계하고 제조할 수 있는 장점을 가지고 있어 조선, 우주 항공, 자동차, 의료,기계 등 다양한 분야에서 사용되고 있다.이러한 금속 3D 프린팅은 크게 Powder Bed Fusion(PBF) 공정과 Directed Energy Deposition(DED) 공정으로 분류할 수 있다.

PBF는 금속 파우더를 소재로 하는 공정으로 파우더를 평평히 깔고, 고밀도 에너지를 가진 레이저 또는 전자빔을 지정된 영역에 조사(Irradiation)하여 파우더를 소결시키거나 용융시켜 한 층씩 적층하는 방법이다. DED는 고출력 레이저 빔을 금속 표면에 조사하면서 동시에 금속 파우더도 같이 분출되어 용융지가 실시간으로 적층되는 공정이다. 용접과 유사한 방법으로 기존 제품에 덧붙여 쌓아 올릴 수 있어 보수 작업에 활용할 수 있다. 그리고, DED 공정에서는 이종 소재의 적층이 가능하여 다양한 금속 파우더를 활용한 합금 제작이나 다른 재질을 소재를 적층할 수 있다

Powder Bed Fusion(PBF) 공정

FLOW-3D의 Weld 모듈을 이용하여 레이저 파워, 열 유속, 레이저 Spot 사이즈, 레이저 움직임과 속도, 실드 가스, 멀티 반사효과, 반사율, 증발압력 효과, 표면장력 설정 등을 고려하여 Powder에 레이저조사 조건을 설정하여 용융거동을 확인할 수 있다.

Directed Energy Deposition(DED) 공정

DED 공정 해석은 FLOW-3D의 Particle 기능을 이용한 방법으로, Base Metal에 입자들이 낙하되면서 레이저의 열유속에 의해 용융 및 적층된다. 이 방법은 입자가 떨어지는 현상을 시각적으로 확인할 수 있다.

Microfluidics와 nanofluidics는 나노와 나노사이의 기능을 가진 재료와 시스템을 통한 유체 흐름의 과학과 기술을 포함하는 분야입니다. 최근 몇 년 사이에 이 분야의 연구는 재료 개발과 시스템의 급속한 발전된 유체공정의 독특한 이점으로 증가해 왔습니다. Microfluidic 및 nanofluidic 시스템은 화학 반응, 유체 가열, 혼합 및 감지와 같은 순차적 또는 다중화된 공정을 포함할 수 있는 응용 분야에서 마이크로 사이즈의 유체 유동은 매우 효율적이고 반복 가능하며 신속한 처리를 가능하게 합니다. 풀 라니 (Furlani) 교수 그룹의 연구는 새로운 공정 및 장치 개발에 대한 모델링 및 시뮬레이션을 보여줍니다. 이 연구의 대부분은 뉴턴 및 비 뉴턴 유체, 열 전달, 상변화 분석, 자유표면 및 다상분석, 유체와 관련된 유체 현상을 연구하기 위해 최첨단 전산 유체역학을 강조합니다. 매체 상호작용, 다공성 매체를 통한 유동, 완전히 결합된 유체구조 및 입자, 유체 상호작용에 대해 콜로이드. 국제 나노 기술 학술 대회에서 3 편의 논문이 발표될 예정입니다. 2014년 6월 15일부터 18 일까지 워싱턴 DC의 Gaylord National Hotel 및 Convention Center에서 개최됩니다. 이들은 버팔로 대학교 (University at Buffalo)에서 진행되는 획기적인 결과를 선보입니다. 여기에서는 이러한 작품의 미리 보기와 FLOW-3D로 생성된 시뮬레이션 결과 중 일부를 제시합니다.

Colloidal 귀금속 (plasmonic) 나노 구조는 나노 입자 합성에서부터 바이오 이미징 (bioimaging), 의학 요법 (medical therapy)에 이르기까지 다양한 광열 (photothermal) 분야에서 점점 더 많이 사용되고 있습니다. 많은 응용분야에서, 펄스 레이저는 plasmonic 공진 주파수에서 나노 구조를 사용하며, 이는 광자의 흡수 및 고도로 국부화된 파장필드의 향상을 가져옵니다. 원격 소스로부터 효율적인 나노 스케일 가열하는 것 외에도, 합성동안 나노 입자의 구조를 조정함으로써 근적외선 스펙트럼을 통한 공진 가열파장을 조정할 수 있습니다. 우리 그룹은 nanosecond-pulsed, laser-heated colloidal metallic nanoparticles 및 열 유체 거동을 예측하는 전산모델을 개발했습니다. 이 모델은 플라즈몬 공명, 입자에서 주변 유체로의 열 전달 및 균일한 기포 핵 형성을 유도하는 유체의 위상변화에서 나노 입자 내의 에너지 전환을 시뮬레이션 하는데 사용되었습니다. nanorods, nanotori, nanorings 및 nanocages 등 다양한 nanoparticle 형상이 연구되었습니다. 이 분석은 레이저 강도, 입사 파장, 편광, 펄스 지속 시간 및 나노 입자의 방향 및 모양과 같은 공정 매개 변수가 광열 공정을 최적화하도록 조정될 수 있음을 보여줍니다. Plasmonic nanoparticles는 악성 조직의 약물 치료, 약물 전달 및 생체치료에 사용됩니다.

Laser Metal Deposition and Fluid Particles

FLOW-3D의 신규 모듈 개발을 하면서, 입자 모델의 새로운 입자 부류 중 하나인 유체 입자의 기능에 초점을 맞출 것입니다. 유체 입자는 증발 및 응고를 포함하여 유체 속성을 본질적으로 부여합니다. 유체 입자가 비교적 간단한 강우 모델링에서 복잡한 레이저 증착(용접) 모델링에 이르기까지 다양한 사례가 있을 수 있습니다.

Fluid Particles

FLOW-3D에서 유체 입자 옵션이 활성화 되면 사용자는 다양한 직경과 밀도의 다양한 유체 입자 종을 설정할 수 있습니다. 또한 유체 입자의 동력학은 확산 계수, 항력 계수, 난류 슈미트 수, 반발 계수 및 응고 된 반발 계수와 같은 특성에 의해 제어 될 수 있습니다. 유체 입자는 열적 및 전기적 특성을 부여 받을 수도 있습니다.

사용자는 유체 입자 생성을 위해 여러 소스를 설정할 수 있습니다. 각 소스는 이전에 정의 된 모든 유체 입자 종 또는 일부 유체 입자 종의 혼합을 가질 수 있습니다. 또한 사용자는 무작위 또는 균일 한 파티클 생성을 선택하고 파티클이 소스에서 추출되는 속도를 정의 할 수 있습니다.

Laser Metal Deposition

레이저 금속 증착은 함께 미세한 금속 분말을 융합하여 입체 금속 부품을 제작하는 3D printing 공정이다. 레이저 금속 증착는 항공 우주 및 의료 정형 외과 분야에서 다양한 응용 프로그램을 찾습니다. 레이저 금속 증착의 개략도는 아래와 같습니다. 전력 밀도 분포, 기판의 이동 속도, 차폐 가스 압력 및 용융 / 응고, 상 변화 및 열전달과 같은 물리적 제어와 같은 제어 매개 변수가 함께 작동하여 레이저 금속 증착을 효과적인 첨가제 제조 공정으로 만듭니다.

 

Setting Up Laser Metal Deposition

새로운 유체 입자 모델은 분말 강도 분포를 할당하고 용융 풀 주변에서 발생하는 복잡한 입자 – 기판 상호 작용을 포착하기 때문에 레이저 금속 증착 시뮬레이션을 설정하는 데 없어서는 안될 부분입니다.

일반의 사용자들은 FLOW-3D에서 시뮬레이션을 쉽게 설정할 수 있다는 점을 계속 알고 있을 것입니다. 레이저 금속 증착 설정의 경우에도 다른 점은 없습니다. IN-718의 물리적 특성, 형상 생성, 입자 분말 강도 분포, 메쉬 생성 및 시뮬레이션 실행과 같은 모든 설정 단계는 직접적이고 사용자 친화적입니다.

IN-718의 물성은 기판과 응고 된 유체 입자 모두에 사용됩니다. 40 미크론 유체 입자가 무작위 방식으로 초당 500,000의 속도로 입자 영역에서 계산 영역으로 주입됩니다. 입자 빔은 기판의 운동 방향이 변화 될 때마다 순간적으로 정지되어 용융 풀이 급격한 속도 변화에 적응하도록 합니다. 이렇게 하면 기판에서 입자가 반사되는 것을 방지 할 수 있습니다. 매 5 초마다 기판이 회전하기 때문에 입자 생성 속도는 아래 그림과 같이 5 초마다 0으로 떨어집니다. 기판 이동 자체는 표 형식의 속도 데이터를 사용하여 FLOW-3D에 지정됩니다. 입자는 응고 된 유체 입자로 주입되어 고온의 용융 풀에 부딪혀 녹아 용융 풀 유체의 일부가 됩니다.


Substrate velocity

입자 모델 외에도 FLOW-3D의 밀도 평가, 열 전달, 표면 장력, 응고 및 점도 모델이 사용됩니다. 보다 구체적으로, 온도에 따른 표면 장력은 증착 된 층의 형태에 큰 영향을주는 Marangoni 효과를 일으킵니다.

레이저를 복제하기 위해 100 % 다공성 구성 요소가있는 매우 기본적인 설정이 열원으로 사용됩니다. 100 % 다공성은 구성 요소 주변의 유동 역학에 영향을 미치지 않습니다. 오히려 그것은 특정 영역의 기판에 열을 효과적으로 부가한다. 이 예비 가열 메커니즘을 자회사인 Flow Science Japan이 개발 한 고급 레이저 모듈로 교체하는 작업이 현재 본격적으로 진행 중입니다. 가열 다공성 구성 요소는 각각의 층이 동일한 양의 열을 얻도록 각 층이 증착 된 후에 약간 위로 이동됩니다.

Results and discussion

아래 애니메이션은 다중 층 증착을 이용한 레이저 금속 증착 공정을 보여줍니다. 기판이 방향을 바꿀 때마다 입자 빔 동작의 일시적인 정지를 확인하십시오. 또한, 층이 증착됨에 따라, 새로운 층의 형상은 다공성 열원으로부터 각 층에 열의 불균등 한 첨가로 인해 변화됩니다. 각 층을 증착 한 후에 열원을 위로 이동해야 하는 양을 측정하는 것은 현재의 기능에서는 어렵습니다. 다만  준비중인 Flow Science Japan의 레이저 모듈은 이 문제를 해결할 수 있습니다.

전반적으로 입자 모델은 레이저 금속 증착에서 매우 중요한 공정 매개 변수 인 분말 강도 분포를 정확하게 재현합니다. 입자 모델과 같은 수준의 제어와 정교함은 첨가제 제조 분야의 사용자와 공급자 모두가 제조 프로세스를 미세 조정하는 데 도움이 될 것으로 기대합니다.

최근 몇 년 동안 허리케인은 멕시코만 연안의 4개 주에서 여러 해안 고속도로 교량에 구조적 피해를 입혔습니다. 허리케인 피해를 방지하기 위해 연안 교량에 가해지는 파도 하중의 크기는 합리적인 정확성을 가지고 결정되어야 합니다. 일반적으로 구조에 대한 파도 하중의 계산은 구조 상호작용의 여러 특성으로 인해 복잡해집니다. 이 본문은 이러한 복잡한 문제들 중 해결할 수 있는 몇 가지를 보여줍니다.

Validation of Stokes Nonlinear Wave Solution in FLOW-3D

FLOW-3D는 해안 교량의 파도 하중을 계산하고 구조물 고도 및 녹색갑판 위의 물 하중에 대한 영향을 조사하기 위해 사용되었습니다.  FLOW-3D에서 StokesWave의 정확도를 평가하기 위해 계산 도메인의 세개 지점을 선택했습니다(그림 1). 시뮬레이션을 하는 동안, 각 입자 소스는 초당 10개의 입자를 방출했습니다. 입자 궤적은 그림 1에 표시되어 있습니다. 한 지점의 입자 속도를 이론적 결과와 비교했습니다(그림 2a 및 2b). FLOW-3D에 의해 계산된 입자의 역학은 Stokes비선형 파동이론과 잘 일치한다고 결론내렸습니다.

Wave Loads vs. Superstructure Elevations

다리 갑판을 다른 높이로 설정하고 2m파형 높이와 6초 주기의 파형으로 시뮬레이션을 수행했습니다. 그림 3은 파형력이 최대치에 있을 때의 파동 단면과 압력 등고선을 보여 줍니다.

Figure 3. Wave profile and pressure contours at different moments (Pressure unit: Pa).

Flow Field under Bridge Deck

시뮬레이션은 다른 파도 높이로 실행되었습니다. 그림 4에서 볼 수 있듯이 교량 바닥판 밑의 유동장은 복잡합니다. 대들보와 상부 구조물에 의해 형성된 개방된 공간내에서, 물의 흐름은 경계를 따라 원형패턴으로 있었습니다. 또한 유동의 복잡성은 웨이브 높이가 증가함에 따라 증가하는 것으로 관찰되었다.

Observations

시뮬레이션 결과에서 다음과 같은 결론을 도출할 수 있습니다.

  1. 상부 구조물의 높이가 증가함에 따라 교량 상부 구조물의 수직 방향 파동력이 감소하는 반면, 수평 방향 파형력은 교량의 상부 구조물의 상부 표면이 웨이브 높이의 아래에 있을 때 큰 영향을 미치지 않습니다.
  2. 교량 상층부의 물 하중은 파고와 함께 증가합니다. 파손이 거의 발생하는 경우 최대 물 하중이 최대 수직 파력의 50 %를 초과했습니다. 그러나 그린 워터 하중과 상향 파력 사이의 위상차로 인해 수직 파력의 최대 값은 물의 부하에 의해 현저히 감소하지는 않았습니다.
  3. 교량 상부 구조물 주위의 유동장은 평행한 대들보에 의해 차단됩니다. 그러므로 웨이브 힘에 대한 순전히 기반한 방법은 웨이브 힘을 계산하는데 사용할 수 없습니다.

FLOW-3D DEM

FLOW DEM

 

FLOW DEM 은 FLOW-3D 의 기체 및 액체 유동 해석에 DEM(Discrete Element Method : 개별 요소법) 기법인 입자의 거동을 분석해주는 제품입니다.

입자 – 입자 간, 입자 – 벽 사이의 접촉이나 상호 작용을 모델링 할 수 있으므로 보다 현실적인 입자 거동의 해석이 가능합니다. 
또한 유체 부분은 전문적인 FLOW-3D 분석 기능을 사용하기 때문에 유체 와 입자거동의 연성해석을 정밀하게 또한 효율적으로 분석할 수 있습니다.

주요 기능 :
  • 고체 요소의 충돌, 스프링(Spring) / 대시 포트(Dash Pot) 모델 적용
  • Void, 1 fluid, 2 fluid(자유 계면 포함) 각각의 모드에 대응
  • 가변 밀도 / 가변 직경
  • 입자 크기조절로 입자 특성을 유지하면서 입자 수를 감소
  • 독립적인 DEM의 Sub Time Step 이용

Discrete Element Method : 개별 요소법

다수의 고체 요소의 충돌 운동을 분석하는 데 유용합니다. 유동 해석과 함께 사용하면 광범위한 용도에 응용을 할 수 있습니다.

  • 힘은 법선 방향과 접선 방향으로 나누어진다

분석 모드

기본적으로 이용하는 운동 방정식은 FLOW-3D 에 사용되는 질량 입자의 운동 방정식과 같은 것이지만, 여기에 DEM으로 평가되는 항목이 추가되는 형태로 되어 있으며, 실제 시뮬레이션으로는 ‘void + DEM’, ‘1 Fluid + DEM’ , ‘ 1 Fluid 자유계면 + DEM ‘을 기본 유동 모드로 취급이 가능합니다.

입자 타입도 표준 기능의 질량 입자 모델처럼 입자 크기 (반경)와 밀도가 동일한 것 외, 크기는 같지만 밀도가 다른 것이나 밀도는 같지만 크기가 다른 것 등도 취급 가능합니다. 이로 인해 표준 질량 입자 모델에서는 입자 간의 상호 작용이 고려되어 있지 않기 때문에 모든 아래에 가라 앉아 버리고 있었지만, FLOW DEM을 이용하여 기하학적 관계를 평가하는 것이 가능합니다.

DEM은 일반적으로 다수의 입자를 필요로 하는 해석에 사용이 되고 있습니다. 다만 이 경우, 계산 부하가 높아지므로 현실적인 계산자원을 고려하면, 입자 수가 줄여 해석할 필요가 있습니다 .

Particle Size Increase 경우

 

중자 모래 분사 분석

DEM에서의 계산부하를 생각할 때는 입자모델에 의한 안정제한을 고려해야 하지만 서브타임스텝이라는 개념을 도입함으로써 입자의 경우와 유체의 경우의 타임스텝을 바꾸고 필요이상으로 계산시간을 들이지 않고 효율적으로 계산하는 것을 가능하게 하고 있습니다.

이를 통해 예를 들어 중자사 분사 시뮬레이션 실험에서는 이러한 문제로 자주 이용되는 빙엄 유체에서는 실험과의 정합성이 별로 좋지 않기 때문에 당사에서는 이전부터 입상류 모델이라는 모델을 개발하고 연속체로부터의 접근에서도 실험과의 높은 정합성을 실현할 수 있는 모델화를 해왔는데, 이번에 DEM을 사용해도 그것과 거의 같은 결과를 얻습니다. 할 수 있음을 확인할 수 있었다.

시뮬레이션은 다른 파도 높이로 실행되었습니다. 그림 4에서 볼 수 있듯이 교량 바닥판 밑의 유동장은 복잡합니다. 대들보와 상부 구조물에 의해 형성된 개방된 공간내에서, 물의 흐름은 경계를 따라 원형패턴으로 있었습니다. 또한 유동의 복잡성은 웨이브 높이가 증가함에 따라 증가하는 것으로 관찰되었다.

Observations

시뮬레이션 결과에서 다음과 같은 결론을 도출할 수 있습니다.

  1. 상부 구조물의 높이가 증가함에 따라 교량 상부 구조물의 수직 방향 파동력이 감소하는 반면, 수평 방향 파형력은 교량의 상부 구조물의 상부 표면이 웨이브 높이의 아래에 있을 때 큰 영향을 미치지 않습니다.
  2. 교량 상층부의 물 하중은 파고와 함께 증가합니다. 파손이 거의 발생하는 경우 최대 물 하중이 최대 수직 파력의 50 %를 초과했습니다. 그러나 그린 워터 하중과 상향 파력 사이의 위상차로 인해 수직 파력의 최대 값은 물의 부하에 의해 현저히 감소하지는 않았습니다.
  3. 교량 상부 구조물 주위의 유동장은 평행한 대들보에 의해 차단됩니다. 그러므로 웨이브 힘에 대한 순전히 기반한 방법은 웨이브 힘을 계산하는데 사용할 수 없습니다.

Aluminum Integral Foam Molding Process

알루미늄 폼은 우수한 댐핑 및 높은 에너지 흡수율 및 굴곡 강성과 같은 예외적인 특성을 보여줍니다[1]. 강성은 특히 하중 지지 및 경량 구조에 사용하기에 특히 매력적입니다. 중량별 강성을 높이고 보다 우수한 하중 전달을 위해 알 Aluminum Foam Sandwiches (AFS)와 같은 컴팩트한 특성이 필요합니다 [2].

Erlangen-Nuremberg 대학의 금속 공학과 기술 위원장은 알루미늄 발포 특성을 점차적으로 생산하기 위해 다이캐스팅 공정인 Integral Foam Molding 개발하였습니다(그림 1 참조). 이 공정은 폴리머의 사출 성형으로 개발되었으며 따라서 컴팩트한 층을 가진 복잡한 폼을 비용 효율적으로 대량 생산에 적합합니다. 이 노트에 설명 된 시뮬레이션 기법은 프로세스 매개 변수를 선택하는데 도움을 주기 위한 모델링프로세스를 확인할 수 있습니다.

Aluminum Integral Foam Molding Technology

일정량의 발포제 (수소화 마그네슘, MgH2)가 러너 시스템에 배치되고 샷 챔버는 알루미늄 용융물로 채워진다 (공정은 그림 2에 묘사되어 있으며, 공정은 [3]에 자세히 설명되어있다). 피스톤이 진행됨에 따라, 분말은 난류 방식으로 주형에 이송된다. 기술 변형 “고압 일체형 폼 몰딩 (HP-IFM)”의 경우 표준 다이캐스팅 공정에서 알 수 있듯이 이 부품은 주변의 높은 압력에서 완전히 채워져 우수한 표면 품질을 보장합니다. 템퍼링된 금형 표면에서 시작하여 용융물은 일체형으로 고형화되기 시작합니다. 몇 밀리 초가 지나면 금형은 코어 풀러 시스템 위에 열리고 부피는 국부적으로 증가하고 압력은 감소하여 열분해 및 수소화 마그네슘 입자의 수소 방출로 인해 여전히 반고체 내부 영역에서 기공 성장을 시작합니다. 모든 발포제 입자는 이웃하는 공극의 역압에 의해 멈추어 질 때까지 공극의 성장을 지속합니다. 발포된 입자의 벽은 알루미늄 합금의 응고된 입자에 의해 안정화가 되며 이를 endogenous stabilization이라고 합니다[4].

Figure 2. Schematic process cycle of “High Pressure Integral Foam Molding (HP-IFM)” of aluminum.

주조 부품의 전체 부피에서 균일한 형태에 대한 전제조건은 분해 순간의 양호한 입자분포입니다. 또한, 발포제 유입시의 용융물의 온도는 수소화 마그네슘의 분해를 결정하며 (그림 3 참조), 게다가 발포시 solid phase의 양을 결정한다. 그러나 고상의 양이 너무 많으면 기공의 강성이 증가하고 현상 기공의 구형화를 방해하여 구조가 파괴된다 [2].

일체형 발포 성형 공정시뮬레이션은 새로운 부품 설계의 몰드 충진 특성을 조사하는 데 도움이 될 뿐만 아니라 입자 침투도 예측하고 비용을 절약할 수 있게 발포 공정 조건을 결정할 수 있는 강력한 도구입니다. 현재 연구의 목표는 다공성 수준을 일정하게 유지하면서 기공 크기를 줄이는 것입니다. 전산 유체 역학 (CFD) 시뮬레이션은 가능한 한 현재의 프로세스 한계에 가깝게 접근할 수 있습니다. 발포 형태의 개선은 기계적 물성에서 균질 한 구조를 유도 할뿐만 아니라 기계적 성질에 의해 더 얇은 부품의 생산이 가능할 것입니다. 이 목적은 용융물 내에서의 높은 입자 분포 밀도와 동시에 응집 현상의 감소와 함께 완전히 안정된 기공 성장에 의해서만 달성 될 수 있다.

Adapting the Simulation Parameters to Practical Integral Foam Molding Experiments

입자 거동이나 온도장에 대한 신뢰성 있는 예측을 위한 CFD 시뮬레이션을 사용할 수 있으려면 실제 실험과 일치하도록 매개 변수를 결정해야 합니다. 이를 위해, 30-130 ms의 지연 시간을 갖는 일체형 발포 부품을 제작하였으며 성형 팽창 및 기공 성장 개시 순간에 고상분율 때문에 발포 형성이 불가능한 다른 밀도의 형상을 만들었습니다. 열 전달 계수 (완전한 액체 용융물과 완전 응고된 용융물)를 변화시켜 합금 AlSi9Cu3 (Fe)의 주조 사이클을 시뮬레이션하면 응고 곡선을 적용할 수 있습니다. 이러한 목표를 달성하기 위해 시뮬레이션을 피스톤 이동이 시작되기 전에 실제 온도분포를 묘사해야 합니다. 온도는 배치된 열에 의해 숏 챔버에서 국부적으로 측정되었으며 시뮬레이션 내 실제 데이터와 잘 일치하여 성공적으로 묘사 될 수 있었습니다. 금형 충진 중에 금형 표면에서 온도 측정을 참조 할 수도 있습니다. 시간 경과에 따른 그 변화는 시뮬레이션 결과와 잘 일치합니다.

표면장력이나 응고 항력계수와 같은 용융의 유동을 정의하는 추가 매개 변수 단계에서는 다른 설정과 시뮬레이션을 비교하여 조정됩니다. 시뮬레이션 내에서 용융물의 흐름이 실제 시험과 일치하는 즉시 매개 변수가 설정됩니다

Conclusion

전체적으로 FLOW-3D는 실제 생산 전에 새로운 부품 제조의 잠재적 결함을 조사하는 중요한 수단이 될 수 있다는 것을 증명할 수 있었습니다. 이러한 방식으로, 차가운 흐름 또는 데드 존이 없는 성공적인 충전 및 발포제 분포가 보장 될 수 있다. 또한, 예상되는 온도 필드의 정확한 묘사로, 수소화 마그네슘의 분해 특성 및 기공형성을 예측할 수 있습니다. 이는 일체형 폼 구조와 관련하여 고객의 요구를 충족시키기 위한 공정 변수를 정의 할 수 있는 가능성을 제공합니다

CFD에 대해서

What You Should Know About CFD Modeling when Selecting a CFD Package

유체 흐름 및 열 전달 해석용 소프트웨어 패키지에는 여러 형태가 있습니다. 물리적 근사와 수치 해법의 기법이 패키지마다 크게 다르기 때문에 적절한 패키지를 선택하는 것은 매우 어렵습니다. 다음 설명에서는 열유동 시뮬레이션 소프트웨어를 선택할 때 고려해야 할 중요한 몇 가지를 소개합니다.

Software packages for fluid flow and heat transfer analysis come in many forms. These packages differ greatly in their physical approximations and numerical solution techniques, which makes the selection of a suitable package a challenging proposition. The following discussion covers some important items to consider when choosing flow simulation software.

Meshing and Geometry

유한 요소 또는 “body-fitted coordinates”를 채용하고 있는 수치해석 방법은 유체 영역의 기하학적 형상에 적합한 격자를 생성해야 합니다. 정확한 수치 근사치를 얻기 위해 허용 할 수 있는 요소 크기 및 형상에서 이러한 격자를 생성하는 것은 매우 중요한 작업입니다.

복잡한 경우에는 이와 같은 방법으로 격자를 생성하면 며칠 또는 몇 주가 걸릴 수 있습니다.  어떤 프로그램은 사각형의 격자 요소만을 사용함으로써 문제를 해결하려고 하지만, 그럴 경우에는 경계부분에 계단이 생기고 흐름과 열전달 특성이 달라지는 문제에 직면하게 됩니다.

FLOW-3D는 FAVOR™(면적율 / 부피 비율)법 을 사용하여 지오메트리의 특성을 원활하게 포함하므로써, 간단한 사각형 격자만으로도 두 문제를 해결할 수 있습니다.  또한, 간단하고 강력한 솔리드 모델러가 FLOW-3D 패키지에 기본 포함되어 있으며, CAD 프로그램에서 생성한 기하형상 데이터를 가져올 수 있습니다.

Solution methods that employ finite-element or “body-fitted coordinates” require the generation of a solution grid that conforms to the geometry of the flow region. It is a non-trivial task to generate these grids with acceptable element sizes and shapes for accurate numerical approximations. In complicated cases this type of grid generation may consume days or even weeks of effort. Some programs attemptto eliminate this generation problem by using only rectangular grid elements, but then they must contend with “stair-step” boundaries that alter flow and heat-transfer properties. FLOW-3D solves both problems by using easy-to-generate rectangular grids in which geometric features are smoothly embedded using the FAVOR™ (fractional area/volume) method. A simple and powerful solids modeler is packaged with FLOW-3D or users may import geometric data from a CAD program.

Momentum Equation vs. Approximate Flow Models

유체 운동량의 정확한 처리가 중요한 몇 가지 이유가 있습니다.  첫째, 이것은 복잡한 기하학적 형상에서 유체가 어떻게 흐르는지를 예측하는 유일한 방법입니다.  둘째, 액체에 의하여 걸린 동적인 힘(압력)은 운동량에서만 계산할 수 있습니다.  마지막으로, 열 에너지의 대류 수송을 계산하려면 다른 유체 입자 및 경계에 대한 개별 유체 입자의 상대적인 움직임을 정확하게 파악하는 것이 필요합니다. 이것은 운동량의 정확한 처리를 의미합니다.  운동량 보존을 대충 근사하기만 한 CFD 모델은 FLOW-3D에서는 사용되지 않습니다.  이러한 모델은 현실적인 유체 구성 및 온도 분포 예측에 사용할 수 없기 때문입니다.

An accurate treatment of fluid momentum is important for several reasons. First, it is the only way to predict how fluid will flow through complicated geometry. Second, the dynamic forces (i.e., pressures) exerted by the fluid can only be computed from momentum considerations. Finally, to compute the convective transport of thermal energy, it is necessary to have an accurate picture of how individual fluid particles move in relation to other fluid particles and confining boundaries. This implies an accurate treatment of momentum. Simplified flow models that only crudely approximate the conservation of momentum are not used in FLOW-3D because they cannot be used to predict realistic fluid configurations and temperature distributions.

Liquid-Solid Heat Transfer Area

액체와 고체 사이 (금속 주형 등)의 열전달은 경계면 면적의 정확한 추정이 필요합니다.  경계가 계단 모양으로 되어 있는 경우, 보통 이 면적이 크게 추정됩니다.  예를 들어, 실린더의 표면적은 약 27 %정도 크게 추정됩니다.  FLOW-3D의 경우 정확한 경계면 면적은 FAVOR™법에 따라 FLOW-3D 전처리기에서 컨트롤 볼륨마다 자동으로 계산됩니다.

Heat transfer between a liquid and a solid (e.g., metal-to-mold) requires an accurate estimate of the interfacial area. Stair-step boundaries over-estimate this area; for example, the surface area of a cylinder would be over-estimated by a factor of 27%. Accurate interfacial areas are automatically computed by the FAVOR™ method for each control volume in the FLOW-3D pre-processor.

Control Volume Effects on Liquid-Solid Heat Transfer

컨트롤 볼륨의 크기가 액체와 고체 사이에서 교환되는 열 비율과 양에 영향을 줄 수 있습니다.  이것은 열이 액체와 고체의 경계면을 포함하는 컨트롤 볼륨을 흐를 필요가 있기 때문입니다.  FLOW-3D는 액체와 고체의 경계면에 걸쳐 열 전달률을 계산할 때 컨트롤 볼륨의 크기와 전도율이 고려됩니다.

The size of control volumes can influence the rate and amount of heat exchanged between a liquid and solid because heat must also flow in the control volumes containing the liquid/solid interface. In FLOW-3D control volume sizes and their conductivities are accounted for when computing heat transfer rates across liquid-solid interfaces.

Implicitness and Accuracy

비선형 방정식과 결합 방정식의 Implicit 방법은 반복 될 때마다 under-relaxation 특성을 갖는 반복적 해법이 필요합니다.  이 동작은 상황에 따라 심각한 오류 (또는 수렴 속도의 급격한 하락)가 발생할 수 있습니다.  예를 들어, 비율이 큰 컨트롤 볼륨을 사용하는 경우나, 실제로는 중요하지 않은 효과를 예상하고 암시적인 해법을 사용하는 경우 등입니다.  FLOW-3D는 가능한 명시적인 수치해법이 사용되고 있습니다.  이것은 필요한 계산량이 적고, 수치 안정성의 요구 사항이 요구된 정밀도에 상응하기 때문입니다.  자세한 내용은 “암시적인 수치해법과 명시적인 수치해법“을 참조하십시오.

Implicit methods for nonlinear and coupled equations require iterative solution methods that have the character of an under-relaxation in each iteration. This behavior can cause significant errors (or very slow convergence) in some situations, for example, when using control volumes with large aspect ratios or when the implicitness is used in anticipation of an effect that is not actually significant. In FLOW-3D explicit numerical methods are used whenever possible because they require less computational effort, and their numerical stability requirements are equivalent to accuracy requirements. Read more in the Implicit vs. Explicit Numerical Methods article.

Implicit Numerical Methods For Convective Transport

모든 크기의 타임 스텝 크기를 계산에 사용할 수 있는 암시적인 수치 기법은 CPU 시간을 줄이기 위해 많이 사용되는 방법입니다.  불행하게도, 이 방법은 대류 현상 해석에 대해 정확하지 않습니다.  암시적인 해법은 근사 방정식에 확산 효과를 도입함으로써 시간 단계의 독립성을 획득합니다.  수치 확산을 물리적 확산 (열전도 등)에 추가해도 확산율이 변경될 뿐이므로 심각한 문제가 되지 않을 수 있습니다.  그러나 수치 확산(발산)을 대류 과정에 추가하면 모델링 대상의 물리 현상의 특성은 완전히 다르게 됩니다.  FLOW-3D는 시간의 정확한 근사치를 보장하기 위해 프로그램에 의해 time step이 자동으로 제어됩니다.

Implicit numerical techniques that allow arbitrarily large time-step sizes to be used in calculations are a popular way to reduce CPU time requirements. Unfortunately, these methods are not accurate for convective processes. Implicit methods gain their time-step independence by introducing diffusive effects into the approximating equations. The addition of numerical diffusion to physical diffusion, e.g., to heat conduction, may not cause a serious problem as it only modifies the diffusion rate. However, adding numerical diffusion to convective processes completely changes the character of the physical phenomena being modeled. In FLOW-3D time steps are automatically controlled by the program to ensure time-accurate approximations.

Relaxation and Convergence Parameters

암시적으로 근사치를 사용하는 수치법은 하나 이상의 수렴 및 완화(이완)의 매개 변수를 선택해야 합니다.  이러한 매개 변수를 신중하게 선택하지 않으면 발산하거나 수렴에 시간이 걸리는 경우가 있습니다.  FLOW-3D를 융합하는 매개 변수와 완화(이완) 매개 변수를 하나씩만 사용하여 두 매개 변수는 프로그램에 의해 동적으로 선택됩니다.  수치 해법을 제어하는 매개 변수를 사용자가 설정할 필요는 없습니다.

Numerical methods that use implicit approximations also require the selection of one or more convergence and relaxation parameters. Making poor choices for these parameters can lead to either divergences or slow convergence rates. Only one convergence and one relaxation parameter are used in FLOW-3D, and both parameters are dynamically selected by the program. Users are not required to set any parameters controlling the numerical solver.

Free-Surface Tracking

액체와 기체의 경계면 (자유 표면 등)의 모델링에 사용되는 방법은 두 가지가 있습니다.  하나는 액체, 기체 두 영역의 흐름을 계산하고 경계면을 유체 밀도의 급격한 변화로 처리하는 방법입니다.

일반적으로 밀도의 불연속은 고차 수치 근사를 사용하여 모델링됩니다.  불행하게도 이 프로세스는 소수의 격자 셀에서 경계면이 평탄화되고, 이러한 경계면에 보통 존재하는 유체흐름의 접선 속도의 급격한 변화는 고려되지 않습니다.

기체가 계산 영역에 들어가는 액체로 대체되는 경우에는 이 방법에는 기체의 출구 포트 또는 출구 싱크도 보충 할 필요가 있습니다.  또한 이러한 방법은 일반적으로 유체의 비압축성를 충족하기 위해 더 많은 노력이 필요합니다.  이것이 발생하는 기체 영역에 거의 균일 한 압력 조정이 필요하며, 이를 통해 계산 수렴 시간이 소요되기 때문입니다.

FLOW-3D는 VOF (Volume-of-Fluid) 법 이라는 독창적인 방법이 사용되고 있습니다.  이것은 진정한 3 차원 경계면 추적 방식으로, 경계면을  3 차원 인터페이스로 추적하는 체계입니다.  또한 옵션의 표면 장력을 포함한 일반적인 접선 응력 경계 조건은 경계면에 적용됩니다.  기체 영역은 모델에 포함하도록 사용자가 요청하지 않는 한 계산되지 않습니다.

There are two methods used to model liquid-gas interfaces (i.e., free surfaces). One of these is to compute flow in both the liquid and gas regions and to treat the interface as a sharp change in fluid density. Typically, the density discontinuity is modeled using higher-order numerical approximations. Unfortunately, this treatment allows the interface to smooth out over a few grid cells and does not account for a corresponding sharp change in tangential flow velocity that generally exists at such interfaces. This technique must also be supplemented with escape ports or sinks for the gas if it is to be replaced by liquid entering a computational region. Further, such methods must typically work harder to satisfy the incompressibility of the fluids. This happens because gas regions must have nearly uniform pressure adjustments which tend to slow down the solution convergence rate. A different technique, the Volume-of-Fluid (VOF) method, is used in FLOW-3D. This is a true three-dimensional interface tracking scheme in which the interface is closely maintained as a step discontinuity. Moreover, normal and tangential stress boundary conditions, including optional surface tension forces, are applied at the interface. Gas regions are not computed unless the user requests these regions to be included in the model.

Colloidal 귀금속 (plasmonic) 나노 구조는 나노 입자 합성에서부터 바이오 이미징 (bioimaging), 의학 요법 (medical therapy)에 이르기까지 다양한 광열 (photothermal) 분야에서 점점 더 많이 사용되고 있습니다. 많은 응용분야에서, 펄스 레이저는 plasmonic 공진 주파수에서 나노 구조를 사용하며, 이는 광자의 흡수 및 고도로 국부화된 파장필드의 향상을 가져옵니다. 원격 소스로부터 효율적인 나노 스케일 가열하는 것 외에도, 합성동안 나노 입자의 구조를 조정함으로써 근적외선 스펙트럼을 통한 공진 가열파장을 조정할 수 있습니다. 우리 그룹은 nanosecond-pulsed, laser-heated colloidal metallic nanoparticles 및 열 유체 거동을 예측하는 전산모델을 개발했습니다. 이 모델은 플라즈몬 공명, 입자에서 주변 유체로의 열 전달 및 균일한 기포 핵 형성을 유도하는 유체의 위상변화에서 나노 입자 내의 에너지 전환을 시뮬레이션 하는데 사용되었습니다. nanorods, nanotori, nanorings 및 nanocages 등 다양한 nanoparticle 형상이 연구되었습니다. 이 분석은 레이저 강도, 입사 파장, 편광, 펄스 지속 시간 및 나노 입자의 방향 및 모양과 같은 공정 매개 변수가 광열 공정을 최적화하도록 조정될 수 있음을 보여줍니다.

마지막으로 응고딜 장소는 주물 내 가장 늦게 응고되는 위치와 수축 다공성 결함이 형성될 가능성이 있는 위치를 직접 표시합니다. 이러한 장소는 고체 분율 진화 또는 응고 시간으로부터 파생될 수 있지만, 보다 직접적인 시각화 방법이 항상 선호됩니다.

특수 유형의 고정 입자는 “핫 스폿”이라고 불리는 마지막 응고 위치를 식별하고 시각화하는 데 사용됩니다. 이 출력은 응고 모델을 사용할 때 자동으로 생성됩니다. 핫 스폿 입자는 그림 1에 도식적으로 나타난 바와 같이, 모든 인접 영역이 고체화된 후에 응고될 때 셀에 삽입됩니다.

이러한 입자는 최종 자유도 위치를 파악하는 것 외에 이러한 위치에서 수축 다공성 결함의 가능성과 크기를 결정하는 데 사용할 수 있는 다른 속성을 가지고 있습니다. 즉, 셀 응고 시간, 핫 스폿 ID 및 핫 스폿크기,  셀이 응고되는 시간입니다. 핫 스폿 ID는 핫 스폿이 첫번째 지점, 두번째 지점인 순서를 나타냅니다. 마지막으로 핫 스팟크기는 다음 공식으로 계산됩니다.

이 입자들은 마지막으로 동결된 위치를 식별하는 것 외에도 이러한 위치에서 수축 다공성 결함의 가능성 및 크기, 즉 셀 응고 시간, 핫 스폿 ID 및 핫 스폿 크기를 결정하는 데 사용할 수 있는 다른 속성을 가지고 있습니다. 셀 응고 시간은 셀이 응고되는 시간입니다. 핫 스폿 ID는 핫 스폿이 굳어지는 순서를 나타냅니다. 1은 첫 번째, 2는 두 번째 등. 마지막으로, 핫 스폿 크기는 다음 방정식으로 계산됩니다.

 

  • hsm(i) 는 입자 i에 대한 핫스팟 크기입니다.
  • t0 는 입자 위치에서의 세포 응고 시간입니다.
  • νliq(t) 는 시간 t에서 입자를 포함하는 액체 영역의 부피입니다.

Figure 1. A hot spot particle is inserted at the center of a cell when it solidifies after its immediate neighbors become solid.

Figure 2. 핫스팟 입자를 포함하는 액체 부피의 진행상태 예시 : t3> t2> t1.

그림 2는 연결된 액체 지역의 부피가 입자 속도의 함수로서 어떻게 변하는지를 보여 준다. 그런 다음 계산된 양을 정규화하여 모든 핫 스팟 크기 값을 0과 1사이의 범위로 가져옵니다. 이를 통해 다공성 형성에 미치는 잠재적인 영향과 관련하여 주물 내 여러 핫 스폿을 간단하게 비교 분석할 수 있습니다. 값이 높을수록 응고하는 동안 연결된 액체 영역이 커지며 최종-동결 위치에서 다공성 결함이 줄어들 가능성이 높아집니다.

 

The Thermal Modulus Method

열 계수 법은 일반적인 라이저 설계 시 가장 많이 사용되는 방법 중 하나이며, 특히 알루미늄 합금 및 강철 주물에 사용됩니다. 주어진 주물 부품의 경우, 그 계수는 다음과 같이 정의됩니다.

  • V는 주조 부품의 체적이며
  • A는 주조 부품의 표면적입니다.

주물의 기하학적 계수는 구체나 블록과 같은 정규 형상에 대해 계산하기 쉽습니다. 그보다 더 복잡한 것은 보통 모양으로 주조 섹션을 지루하게 근사치를 구하는 것입니다. 또한, 기하학적 계수형 접근 방식은 주물의 기하학적 구조에 전적으로 의존합니다.

실제 주조물은 냉각제와 절연체를 사용하여 응고 진행을 제어합니다. 이러한 형상은 기하 계수 접근 방식에서는 무시된다. 계수 계산을 자동화하고, 동결 융해, 단열 및 기타 주형 변형과 관련된 열 영향을 고려하기 위해 열 계수라고 하는 혁신적인 접근법이 라이저 디자인에 사용된다.

열 계수 접근 방식의 경우 먼저 주조물의 응고 시뮬레이션이 실행됩니다. 시뮬레이션이 완료되면, Cavorinov의 규칙에 근거한 응고 시간으로부터 주물 전체의 등가 계수를 계산할 수 있습니다. 이 접근법을 사용하여 계산된 등가 계수를 열 계수라고 한다. 그것은 라이저 설계를 가이드하기 위해 기하학적 계수와 동일한 방법으로 사용될 수 있다.

 

Chvorinov의 법칙은 응고 시간과의 관계를 나타내며 그 계수는 다음과 같이 쓸 수 있습니다.

  • t is the casting solidification time,
  • N is a constant (usually equal to 2), and
  • B is the mold constant. It can be calculated using the following formula:

주조 공정을 설계할 때 라이저는 적절한 유동을 위해 라이저의 응고 시간이 인접 주조 섹션의 응고 시간보다 긴 방식으로 설계됩니다. Chvorinov의 규칙에 따르면 응고 시간은 주물의 계수에 정비례합니다. 따라서 응고 시간을 비교할 때 모듈화를 직접 비교할 수 있습니다. 모듈형은 기하학적인 양이기 때문에, 모듈형의 비교는 훨씬 단순하게 설계를 할수있습니다. 금속 주조 엔지니어는 실제 주조 공정의 세부 사항을 고려하지 않고도 부품을 적절하게 이송할 수 있도록 계수가 큰 라이저를 설계할 수 있습니다.

 

Application of the New Tools to Cooling and Feeding System Design  

예를 들어, 새로운 도구를 사용하는 증기 터빈 실린더의 절반에 대한 냉각 및 공급 시스템 설계가 제공되고 이 섹션에서 Flow Science China 도움을 받아 논의됩니다. 부품의 외부 치수는 2.83×2.34×1.10미터이고 총 부피는 아래와 같이 약 0.95 세제곱미터입니다. 주물 재료는 탄소강이며 주입 온도는 150°C입니다.

Figure 3. Casting part geometry

첫째, 냉각제와 라이저가 없는 주조물의 응고 시뮬레이션을 실행합니다. 그 목적은 핫 스폿 위치를 확인하고 응고 건조기 및 라이저의 위치와 라이저의 크기를 결정하는 것입니다. 두개의 새로운 도구는 냉기와 라이저 설계를 개선하는 데 사용됩니다.

입자를 응고할 마지막 위치는 각각 셀 응고 시간, 입자 ID 및 핫 스폿 크기로 표시된 다음 그림과 같습니다. 이러한 그림을 통해 핫 스폿 위치와 수축 다공성 결함을 형성할 가능성을 직접 확인할 수 있습니다. 주물의 기하학적 특성에 기초하여, 라이저를 배치하는 위치는 그림의 마지막 프레임과 같이 쉽게 확인할 수 있습니다.

그러나 하단 쉘에 몇개의 핫 스폿이 있으며 이는 라이저를 배치하는 데 적합하지 않습니다. 이러한 위치에서 다공성 결함의 수축을 방지하기 위해 냉각제를 사용하여 응고 패턴을 변경하고 마지막으로 라이저 영역까지 응고시킬 수 있습니다.

Figure 4. Hot spot locations colored by three attributes (clockwise from top left): hot spot solidification time, particle id and hot spot magnitude.

 

Thermal Modulus Computation

계산 된  thermal modulus는 오른쪽에 표시됩니다. 더 큰 값은 응고될 마지막 위치와 일치합니다. 또한 열 모듈러스를 사용하여 핫스팟 위치에서 라이저의 크기를 결정할 수 있습니다.

냉각 및 라이저가 결정되면 냉각 및 라이저 설계를 확인하기 위해 냉각 및 라이저가 포함된 두 번째 응고 시뮬레이션이 실행됩니다. 핫스팟 크기로 채색된 마지막 응고 위치 입자와 thermal modulus가 그림 6에 나와 있습니다. 냉각이 마지막 장소를 라이저 영역으로 성공적으로 응고시키는 것을 볼 수 있습니다. 그러나 라이저 아래에는 여전히 위험한 핫 스팟이 있습니다. 실제로 실제 주조는 아래 그림에 표시된 것처럼 핫스팟 입자로 식별된 위치에서 수축 다공성 결함을 보여줍니다.

 

 

 

Figure 5. Calculated thermal modulus

Calculated thermal modulus 마지막으로 동결할 장소는 라이저가 아닌 주물 안에 있습니다. 즉, 라이저 위치와 크기가 올바르게 결정되더라도 주물이 라이저 쪽 방향으로 굳지 않도록 응고 패턴이 올바르지 않다는 것을 의미합니다. 한 가지 해결책은 발열 라이저 슬리브를 사용하여 응고 패턴을 수정하는 것입니다. 이것은 본 기사의 범위를 벗어나기 때문에, 더 이상 논의되지 않을 것입니다.

Defect Prediction / 결함 예측

Identify Filling Defects using Particles  결함 예측 및 입자를 이용한 주입 결함 식별

파티클을 사용하는 FLOW-3D CAST v5를 통해 유입된 가스로 인한 충전 결함을 식별하는 것이 훨씬 쉬워 졌습니다. 결함을 식별하기가 훨씬 용이할 뿐만 아니라, 결함 예측에 따른 계산 비용도 크게 절감되었습니다.

붕괴된 가스 지역을 나타내는 보이드 입자가 도입되었습니다. 이전에 붕괴된 가스 영역은 너무 압축되어 수치 메쉬에서 해결할 수 없으면 시뮬레이션에서 사라졌습니다. 보이드 입자는 작은 기포처럼 작용하며 드래그와 압력을 통해 금속과 상호 작용합니다. 주변의 금속 압력에 따라 크기가 변하며, 주입이 끝난 후 최종 위치를 보면 공기 침투 및 산화물로 인한 잠재적인 결함이 있음을 알 수 있습니다.

Predict filling defects caused by entrapped gas using the Particle Model.

Metal/Wall Contact Time 금속/벽 접촉 시간

벽면 접촉 시간은 금형 표면에서 다른 부위보다 금속에 더 오래 노출된 부위를 식별하는 데 유용합니다. 금속 접촉 시간은 금속이 고체 구성 요소와 접촉한 시간을 나타냅니다. 예를 들어 모래 입자가 핵분해 부위의 역할을 하기 때문에 미세 먼지가 발생할 수 있습니다. 개별 솔리드 구성 요소와의 금속 접촉 시간 출력이 모든 구성 요소와의 접촉 시간을 포함하도록 확장되었습니다. 접촉 시간 계산은 출력 탭에서 벽 접촉 시간을 선택하여 활성화합니다.

Identify solidification defects with the new Thermal Modulus output.

Solidification Defect Identification 응고 결함 식별

일반적으로 라이저 크기 조정에 사용되는 열 모듈은 이제 응고 시뮬레이션에서 출력됩니다.

Risers will likely need to be placed on the circled regions.

Hot Spots  핫 스팟

또 다른 결과인 “핫 스팟”은 라이저를 찾고 크기를 조정하며, 응고 관련 결함의 가능성을 식별하는 데 유용합니다. 핫 스팟은 최종적으로 응고된 부위를 나타냅니다. 이것들은 입자들로 표현되고 뜨거운 점 크기에 의해 색깔이 변하기도 합니다. 라이저는 핫 스팟 크기가 가장 큰 곳에 배치해야 합니다.

Porosity Analysis Tool

FlowSight의 새로운 Porosity Analysis Tool은 실제적인 측면에서 porosity-related 결점을 식별합니다. 결점은 이제 순 볼륨, 최대 선형 범위, 모양 인자 및 total count로 식별됩니다.

New defect identification tools allow users to analyze porosity.

Arbitrary 2D Clips 임의 2D 클립

기능 지향적인 2D 클립은 결함을 찾기 위해 전면적으로 살펴 볼 때 유용합니다. 이전에는 클립에 표시된 금속 영역이 솔리드에 의해 점유된 셀로 확장되었습니다. 잡식의 FLOW-3D CAST v5에서 이 클립은 구성 요소를 숨기는 옵션을 선택해야만 열린 공간(예:주조 부품)의 금속을 보여 줄 수 있습니다.

Intensification Pressure 강화 압력

고압 주조 시뮬레이션에 지정된 강화 압력은 이제 매크로 및 마이크로 Porosity모델 모두에 결합되어 형성 사이의 보다 현실적인 관계를 형성합니다. 이러한 결함의 크기 및 플런저에 의해 가해지는 압력의 크기입니다.

Adjusting Shrinkage Porosity 수축 기공 조절

사용자가 금속의 특성을 수정할 필요 없이 수축 다공성의 양과 크기를 미세 조정할 수 있도록 수축 조정 계수가 추가되었습니다. 계수를 사용하면 응고 중에 체적 수축의 양을 전화로 설정하거나 줄일 수 있습니다.

Gas Pressure and Venting Efficiency  가스 압력 및 밴트 효율성 검토

사용자가 충전 결함을 식별하고 다이캐스트에서 밴트 시스템을 설계하는 데 도움을 주기 위해 마지막 국부적인 가스 압력 및 밴트 효율성 검토 결과가 주조 시뮬레이션 출력에 추가되었습니다. 가스 압력은 셀이 금속으로 채워지기 전에 셀의 마지막 보이드 압력을 기록하며, 밴트 효율은 환기구를 배치하는 것이 밴트 위치에서 공기를 배출하는 데 가장 효율적인 영역을 보여 줍니다.

Databases 데이터베이스

주조 공정에서 일반적으로 사용되는 정보의 데이터베이스는 설정 오류를 줄이고 시뮬레이션 workflow 를 개선합니다.

Configurable Simulation Monitor 구성 가능한 시뮬레이션 모니터

시뮬레이션을 실행할 때 발생하는 중요하지만 종종 힘든 작업은 시뮬레이션을 모니터링하는 것입니다. FLOW-3D CAST를 사용하면 다음과 같은 일반적인 시뮬레이션 목표를 모니터링할 수 있습니다.

  • 게이트 속도
    주형 내 고상 분율
    최저/최고 용탕 온도 및 금형 온도
    다양한 프로브 위치에서의 온도
    시뮬레이션 진단(예:시간 스텝, 안정성 한계)

Plotting Capabilities  Plotting기능

이제 시뮬레이션 관리자에는 더 많은 플롯 기능이 포함됩니다. 플롯은 사용자가 구성할 수 있으며 구성은 다른 시뮬레이션에서 사용하기 위해 데이터베이스에 저장됩니다. 사용자는 시뮬레이션 런타임 그래프와 history-data 에서 모니터링할 이력 데이터 변수를 지정할 수 있습니다. 다중 변수를 각 그래프에 입력합니다.

Conforming Meshes

임의 형상의 활성 계산 영역을 정의할 수 있도록 적합한 메쉬 기능이 확장되었습니다. 이는 메쉬 블록이 준수할 수 있는 열린 볼륨과 솔리드 볼륨을 모두 포함하여 계산 도메인의 영역을 정의하는 meshing구성 요소라고 하는 새로운 유형의 지오메트리 구성 요소를 사용합니다.
메쉬 블록은 냉각 채널이나 공동에 선택적으로 조합할 수 있어 사용자가 이러한 기하학적 객체에 대해 최적의 해상도를 선택할 수 있습니다. 이제 확인할 수 있는 메쉬가 FAVORize 탭에 표시될 수 있습니다.

Summary Views of Components/Cooling Channels

FLOW-3D CAST v5의 인터페이스는 주조 시뮬레이션에서 다양한 형상 구성 요소를 꽉 차게 보여줍니다. 2개의 새로운 형상 요약 뷰인 구성 요소 요약 뷰와 냉각 채널 요약 뷰는 기하학적 구성 요소 및 냉각 채널의 플라이 아웃을 제공하여 사용자가 신속하게 수행할 수 있도록 합니다. 중요 설정을 한 눈에 파악하고 필요한 경우 변경 할 수 있습니다.

Under the Hood

FLOW-3D CAST의 많은 강력한 구성 요소들은 Solver Engine이라고 부르는 것 들에서 중요합니다. 아래에서는 이면에서 무거운 작업을 수행하는 데 도움이 되는 몇가지 중요한 사항을 설명합니다.

Thermal Die Cycling (TDC) Model TDC(열 다이 사이클)모델

열 다이 사이클 시뮬레이션의 주입/응고 단계는 균일하지 않은 캐비티 온도를 사용하여 개선할 수 있습니다. 이제 캐비티에 있는 금속의 초기 온도는 재시작 중에 채우기 시뮬레이션을 통해 지정하거나 초기 유체 영역을 사용하는 사용자 정의 분포에서 지정할 수 있습니다. 이 기능은 옵션으로 사용할 수 있는 균일한 초기 금속 온도에 비해 다이 사이클링의 열해석의 정확성과 현실성을 높여줍니다.

Melt temperatures in the casting cavity read from a filling simulation are applied to ejector die during filling/solidification stage of thermal die cycling simulation.

Heat Transfer Coefficient Calculator for Spray Cooling 분사 냉각을 위한 열 전달 계수 계산기

스프레이 유체와 다이 표면 사이의 열 전달 계수(HTC)를 추정하는 것은 어려운 일입니다. 계산 또는 측정을 통해 값을 사용할 수 있는 경우 사용자는 이러한 값을 스프레이 거리 및 각도의 함수로 직접 지정할 수 있습니다. 새로운 기능을 통해 노즐의 스프레이 액의 유량을 기준으로 HTC를 동적으로 계산할 수 있습니다. 단일 조정 계수를 통해 스프레이 유출량을 기준으로 HTC를 미세 조정할 수 있습니다.

FLOW-3D 개요

FLOW-3D는 미국 뉴멕시코주(New Mexico) 로스알라모스(Los Alamos)에 있는 Flow Scicence, Inc에서 개발한 범용 전산유체역학(Computational Fluid Dynamics) 프로그램입니다. 로스알라모스 국립연구소의 수치유체역학 연구실에서 F.Harlow, B. Nichols 및 T.Hirt 등에 의해 개발된 MAC(Marker and Cell) 방법과 SOLA-VOF 방식을 기초로 하여, Hirt 박사가 1980년에 Flow Science, Inc사를 설립하여 계속 프로그램을 발전시켰으며 1985년부터 FLOW-3D를 전세계에 배포하였습니다.

유체의 3차원 거동 해석을 수행하는데 사용되는 CFD모형은 몇몇 있으나, 유동해석에 적용할 물리모델 선정은 해석의 정밀도와 밀접한 관계가 있으므로, 해석하고자 하는 대상의 유동 특성을 분석하여 신중하게 결정하여야 합니다.

FLOW-3D는 자유표면(Free Surface) 해석에 있어서 매우 정확한 해석 결과를 제공합니다. 해석방법은 자유표면을 포함한 비정상 유동 상태를 기본으로 하며, 연속방정식, 3차원 운동량 보전방정식(Navier-Stokes eq.) 및 에너지 보존방정식 등을 적용할 수 있습니다.

FLOW-3D는 유한차분법을 사용하고 있으며, 유한요소법(FEM, Finite Element Method), 경계요소법(Boundary Element Method)등을 포함하여 자유표면을 포함하는 유동장 해석(Fluid Flow Analysis)에서 공기와 액체의 경계면을 정밀하게 표현 가능합니다.

유체의 난류 해석에 대해서는 혼합길이 모형, 난류 에너지 모형, RNG(Renormalized Group Theory)  k-ε 모형, k-ω 모형, LES 모형 등 6개 모형을 적용할 수 있으며, 자유표면 해석을 위하여 VOF(Volume of Fluid) 방정식을 사용하고, 격자 생성시 사용자가 가장 쉽게 만들 수 있는 직각형상격자는 형상을 더욱 정확하게 표현하기 위해 FAVOR(Fractional Area Volume Obstacle Representation) 기법을 각 방정식에 적용하고 있습니다.

FLOW-3D는 비압축성(Incompressible Fluid Flow), 압축성 유체(Compressible Fluid Flow)의 유동현상 뿐만 아니라 고체와의 열전달 현상을 해석할 수 있으며, 비정상 상태의 해석을 기본으로 합니다.

FLOW-3D v12.0은 모델 설정을 간소화하고 사용자 워크 플로우를 개선하는 GUI(그래픽 사용자 인터페이스)의 설계 및 기능에 있어 중요한 변화를 가져왔습니다. 최첨단 Immersed Boundary Method는 FLOW-3Dv12.0솔루션의 정확도를 높여 줍니다. 다른 특징적인 주요 개발에는 슬러지 안착 모델, 2-유체 2-온도 모델, 사용자가 자유 표면 흐름을 훨씬 더 빠르게 모델링 할 수 있는 Steady State Accelerator등이 있습니다.

물리 및 수치 모델

Immersed Boundary Method

힘과 에너지 손실에 대한 정확한 예측은 솔리드 바디 주변의 흐름과 관련된 많은 엔지니어링 문제를 모델링하는 데 중요합니다. FLOW-3D v12.0의 릴리스에는 이러한 문제 해결을 위해 설계된 새로운 고스트 셀 기반 Immersed Boundary Method (IBM)가 포함되어 있습니다. IBM은 내부 및 외부 흐름을 위해 벽 근처 해석을 위해 보다 정확한 솔루션을 제공하여 드래그 앤 리프트 힘의 계산을 개선합니다.

Two-field temperature for the two-fluid model

2유체 열 전달 모델은 각 유체에 대한 에너지 전달 공식을 분리하도록 확장되었습니다. 이제 각 유체에는 고유한 온도 변수가 있어 인터페이스 근처의 열 및 물질 전달 솔루션의 정확도를 향상시킵니다. 인터페이스에서의 열 전달은 시간의 표 함수가 될 수 있는 사용자 정의 열 전달 계수에 의해 제어됩니다.

슬러지 침전 모델 / Sludge settling model

중요 추가 기능인 새로운 슬러지 침전 모델은 도시 수처리 시설물 응용 분야에 사용하면 수처리 탱크 및 정화기의 고형 폐기물 역학을 모델링 할 수 있습니다. 침전 속도가 확산된 위상의 방울 크기에 대한 함수인 드리프트-플럭스 모델과 달리, 침전 속도는 슬러지 농도의 함수이며 기능적인 형태와 표 형태로 모두 입력 할 수 있습니다.

Steady-state accelerator for free surface flows

이름이 암시하듯이, 정상 상태 가속기는 안정된 상태의 솔루션에 대한 접근을 가속화합니다. 이는 작은 진폭의 중력과 모세관 현상을 감쇠하여 이루어지며 자유 표면 흐름에만 적용됩니다.

꾸준한 상태 가속기

Void particles

보이드 입자가 버블 및 위상 변경 모델에 추가되었습니다. 보이드 입자는 항력과 압력 힘을 통해 유체와 상호 작용하는 작은 기포의 역할을 하는 붕괴된 보이드 영역을 나타냅니다. 주변 유체 압력에 따라 크기가 변경되고 시뮬레이션이 끝난 후 최종 위치는 공기 침투 가능성을 나타냅니다.

Sediment scour model

침전물의 정확성과 안정성을 향상시키기 위해 침전물의 운반과 침식 모델을 정밀 조사하였다. 특히, 침전물 종에 대한 질량 보존이 크게 개선되었습니다.

Outflow pressure boundary condition

고정 압력 경계 조건에는 이제 압력 및 유체 비율을 제외한 모든 유량이 해당 경계의 상류에 있는 흐름 조건을 반영하는 ‘유출’ 옵션이 포함됩니다. 유출 압력 경계 조건은 고정 압력 및 연속성 경계 조건의 혼합입니다.

Moving particle sources

시뮬레이션 중에 입자 소스는 이동할 수 있습니다. 시간에 따른 변환 및 회전 속도는 표 형식으로 정의됩니다. 입자 소스의 운동은 소스에서 방출 된 입자의 초기 속도에 추가됩니다.

Variable center of gravity

Drift Model for Two-Component Flows [두 구성 요소 흐름에 대한 표류 모델]

Overview
In fluids composed of multiple components, e.g., fluid/particles, fluid/bubbles, fluid/fluid mixtures, where the components have different densities, it is observed that the components can assume different flow velocities. Velocity differences arise because the density differences result in non-uniform body forces. Often the differences in velocities can be very pronounced, for example, large raindrops falling through air or gravel sinking in water. Under many conditions, however, the relative velocities are small enough to be described as a “drift” of one component through the other. Examples are dust in air and silt in water.
The “drift” distinction has to do with whether or not the inertia of a dispersed component moving in a continuous component is significant. If the inertia of relative motion can be ignored, and the relative velocity reduced to a balance between a driving force (say gravity or a pressure gradient) and an opposing drag force between the components, then we can speak of a “drift-flux” approximation. Drift velocities are primarily responsible for the transport of mass and energy. Some momentum may be transported as well, but this is usually quite small and has been neglected in the FLOW-3D1 drift model. A more complete analysis of when the “drift” assumption is valid can be found in the Flow Science, Inc.

Simulating the Residue left by Evaporating Drops

Background
The “coffee ring” effect is the name given to a well known observation where the evaporative drying of a drop of coffee leaves behind a ring of dark material at the edge of the original drop. On first thought one would expect that the coffee particles, which are uniformly distributed in the drop, would simply be deposited uniformly over the area wetted by the drop. It has only been in recent years that researchers have uncovered the mechanisms that produce the ring effect (Deegan, R.D., et al).
As currently understood, the edges of drops can become pinned because of roughness or chemical elements on the surface on which they lie. Heat transfer to the drops from the substrate or the air induces evaporation, which is usually greater near the drop edge. Surface tension forces then adjust the curvature of the remaining liquid consistent with the pinned edge, which results in a net flow of liquid toward the edge. This flow replenishes the evaporative loss but also moves solute to the edge where it is concentrated by evaporation. Eventually, this mechanism builds up a ring deposit of solute at the original edge of the drop.
The residue from dried drops has implications for many useful applications, including general coating processes, formation of pixel arrays of organic materials for video displays and for a variety of micro-electro-mechanical (MEMS) devices.
Because many factors control the distribution of dried residue it is desirable to have some means to model the fluid dynamics of the process to aid engineers in making the best choices for each specific application. Such a capability has been incorporated into FLOW-3D1 making it possible to computationally investigate the influence of such parameters as the initial solute concentration, fluid viscosity, volatility of the solvent, evaporation rate, surface tension and initial shape of the drop.
This technical note presents a brief description of the residue formation model and illustrates it with several computations of an evaporating drop subject to different physical conditions.

Addition of Dielectric Phenomena to FLOW-3D

Overview
There are situations where it would be helpful to account for the interaction of electric fields with liquid and solid materials. For example, electrostatic air cleaners rely on the ability to attract small particles in flowing air to a surface where they can be collected and removed from the air. In this case the primary attractive force arises from dielectric polarization of the particles.
Spraying liquid drops onto a surface, as in spray painting, is often improved by electrifying the drops so that they repel one another and produce a more uniform distribution. Also, electrified drops can be driven to overcome air resistance by suitable electric fields.
In many types of micro-electrical-mechanical-systems (MEMS) fluids are caused to move by the application of electric potentials. Usually this behavior is induced by electric forces acting on dielectric polarization charges generated at free fluid surfaces or at the interfaces between two fluids.

In some situations the effects of both dielectrically induced charges as well as free electric charges in a fluid must be considered. For these cases the fluid has some nonzero conductivity that must be accounted for by tracking charge densities and adding additional body forces to the fluid. The range of possibilities when conduction is present includes bound and free charges, recombination, ionization, currents without net charge densities, etc. As described next, we shall limit the present development to a useful subset of the many possibilities.

In this note we describe a set of program developments that give FLOW-3DÒ the capability to model fluid and particulate flows involving both free and induced charge densities. In the current released version of FLOW-3D® (Ver. 7.7) both particles and fluid can contain a fixed charge density, but there is no provision for dielectric materials.

Here we describe the addition of dielectric properties for particles, fluids, and solids. In addition, linear polarization forces acting on particles and fluids by electrostatic fields are added to the momentum equations for fluid and particles.

Movable Fluid Sources in FLOW-3D [FLOW-3D에서 움직이는 유체]

OVERVIEW


There are many examples of fluid flow simulation where it would be useful to have specified fluid sources located inside the computational grid. By “fluid sources” we mean a source of
fluid mass and momentum. Even more useful would be a capability where the location, flow rate, and flow direction of the fluid sources could be specified.
In this Technical Note, we describe a scheme that meets these goals in the FLOW-3D® program.
In the next section we describe the basic approach that was taken to add this capability and following that there are several examples illustrating the method.
MODELING APPROACH FOR GENERAL FLUID SOURCES
A recent addition to FLOW-3D® is the ability to have full momentum coupling between a continuum fluid and discrete mass particles. This addition is described in the Flow Science
Technical Note FSI-99-TN50, “Particle-Fluid Coupling.” It is this capability that forms the basis of our addition for general fluid sources.
For purposes of discussion, suppose that we want to model fluid exiting the end of a pipe placed somewhere inside a computational grid. Fluid exits the end of the pipe with a specified flow rate
and flow velocity, i.e., both magnitude and direction are specified. In the most general case, the velocity distribution over the cross section of the pipe exit could be non-uniform. The location
of the pipe end should be arbitrary, so that moving the pipe by relocating it every time step in a transient computation would be possible.
To meet these goals, we imagine covering the end of the pipe with a set of particles. Each particle is assigned a mass source rate and a velocity corresponding to the fluid flow direction at
its location. We may think of these particles as representing average values of the flow for small areas surrounding them. In this sense, summing up the particles is equivalent to a numerical
integration of the flow over the cross section of the pipe. The particles simply represent the discrete elements of the integration area.

Self-Consistent Electric Fields and Electric Forces On Charged Particles

SCOPE
A recent addition to the computational fluid dynamics program FLOW-3D® is a capability for modeling discrete mass particles moving through a continuum. This model implicitly couples
the particles and continuum so that they may exchange momentum in a conservative way.
This report addresses how that model has been extended to account for mass particles having an electric charge and moving in an electric field. The extension is self-consistent in the sense that
the particle charges contribute to the electric field. For this reason the field is time dependent and must be recomputed for each time step of a numerical simulation.
In addition to the charged particles, solid objects (obstacles) located within the computational region may be assigned arbitrary, but constant in time, potentials. Each obstacle may have a
fixed potential value consistent with the obstacle being a conductor. A zero potential value is the default value if not otherwise specified. It should be noted that an electric potential can be
computed even when there are no charged particles, although this field will have no effect on flow processes unless the user adds some kind of additional interaction to the model.
Mesh boundaries that are rigid walls may be assigned non-zero potential values. All other boundaries are treated as symmetry boundaries with respect to the potential. Furthermore, no
insulated obstacles are allowed in this model. It is also assumed that if there are free fluid surfaces or fluid-fluid interfaces then the dielectric constants (i.e., ratios of material permittivities
to that of vacuum) of the different materials must be the same, otherwise additional development will be needed to solve for the electric potential. In general, this is not correct because the
dielectric constant does vary with material type; for example, water has a dielectric constant about 81 times that for air.

Particle-Fluid Coupling [입자-유체 연동]

There are many important flow situations involving a dispersed liquid or solid material in a continuous gas or liquid. A few everyday examples are fuel injection in a automobile engine,
rain, dust storms and all sorts of atomizers for painting, cleaning and applying medicine. In most cases there are significant interactions between the continuous and dispersed materials
that arise because of the drag experienced by the dispersed particles as they move through the continuous fluid. A secondary interaction effect is the displacement of fluid volume by particle
volume.
Of the two interaction effects, i.e., volume exclusion and momentum exchange, the most important is momentum exchange because this can be significant even when the volume of
particles is small. To see why this is so, consider a typical two-phase system with properties similar to that of water and air. The density ratio between water and air is about 1000. This
means that a liquid fraction of only 10E-4 translates into 10% of the mixture mass. Thus, even when the water volume is a negligible fraction of the whole, it still may account for a significant
portion of the mixture momentum.
