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  피츠버그에있는 Ansys Inc.의 수석 제품 마케팅 관리자인 Bill Kulp는 말합니다 .

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.

Aerospace Sloshing Dynamics

Sloshing Dynamics

우주선의 연료 탱크에서 추진체의 움직임에 대한 지식은 작동 및 성능의 다양한 측면을 이해하는 데 필수적입니다. 추진체 운동은 액체 배출, 가스 배출 및 가압과 같은 추진 기능에 영향을 미칩니다. 어떤 경우에는 추진체 운동에 의해 생성되는 힘도 알아야합니다. 이것은 액체 질량이 전체 우주선 질량의 상당 부분을 포함할 때 특히 그렇습니다.

FLOW-3D: Aircraft Fuel Tank Sloshing
FLOW-3D: Aircraft Fuel Tank Sloshing : 회전과 가속을 하는 동안 전투기의 연료 탱크 시뮬레이션

Visualizing Non-Inertial Reference Frame Motion

연료 탱크 슬로싱은 연료의 slosh 역학을 구성하며, 여기서 연료의 역학은 컨테이너와 상호 작용하여 시스템 역학을 변경할 수 있습니다. 일반적으로 연료에는 자유 표면이 있습니다. FLOW-3D는 TruVOF를 사용한 정확한 자유 표면 추적으로 인해 연료 슬로싱 역학을 시뮬레이션하는 데 탁월한 소프트웨어입니다. 또한 FLOW-3D의 NIRF (Non-Inertial Reference Frame) 모듈을 사용하면 고정된 참조 프레임에서 연료 및 움직이는 컨테이너 (연료 탱크)를 시각화하기 위한 쉽고 계산 효율적인 설정이 가능합니다.

FLOW-3D의 NIRF 모듈 기능을 강조하기 위해 우주 왕복선의 연료 슬로 싱을 보여주는 샘플 시뮬레이션이 설정됩니다. 우주 왕복선은 처음 25 초 동안 위쪽으로 가속한 다음, 다음 25 초 동안 같은 양만큼 감속합니다. 그 후 각 가속도를 사용하여 셔틀이 90도 회전한 다음 다시 선형 가속을 계속합니다. 이 복잡한 우주 왕복선 기동 중에 복잡한 자유 표면 유체 운동을 보는 것은 흥미롭습니다. RNG 난류 모델은 유체의 난류 운동 에너지를 추정하는데 사용됩니다.

애니메이션의 왼쪽 창에는 FlowSight에서 생성 된 NIRF 시각화가 표시되고 오른쪽 뷰포트에는 FlowSight를 사용하여 다시 생성된 비 NIRF 시각화가 표시됩니다. NIRF 시각화는 고정된 기준 프레임에서 유체와 탱크의 움직임을 이해하는데 도움이되므로 시스템의 전반적인 역학을 보다 관련성 있게 강조 할 수 있습니다.

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.

오일 및 가스 분리기

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.

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.

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).

Design of a Sewer Transition

Design of a Sewer Transition | 하수도 전환 설계

This article was contributed by Daniel Valero, Rafael García-Bartual, Ignacio Andrés and Francisco Valles of the Polytechnic University of Valencia.

2010 년 12 월, 새로운 고속 열차 MADRID-VALENCIA (스페인)가 개통되었습니다. 건설 전에 극복해야 할 많은 기술적 문제 중 하나는 터널로 구성된 도심의 철도 입구로 발렌시아의 주요 남쪽 하수도를 벗어나게 했습니다. 이탈 도달 범위는 길이가 143 미터이며 아래에 자세히 설명된 복잡한 유압 설계를 포함하여 기존 경사와 관련하여 경사 및 단면의 중요한 변경을 포함합니다. 유압 성능은 FLOW-3D를 사용한 수치 시뮬레이션과   발렌시아 폴리 테크닉 대학교의 유압 실험실에서 물리적 모델을 통해 확인되었습니다. 최대 용량 100 m 3 / s에 대한 테스트가 수행되었습니다 .

The Sewer                          

그림 1은 하수도 기하학 설계의 주요 특징을 보여줍니다. 여기에는 철도 터널을 건넌 직후에 위치한 표준 WES 프로파일이 포함됩니다. 이 위어는 높은 유속으로 초 임계 흐름을 강제합니다. 하류에서 바람직하지 않은 흐름 조건이 설정되는 것을 방지하기 위해 둑 바로 하류에 정류 조를 설계했습니다. 이러한 장치는 연결 하류 하수도에서 높은 에너지 손실 및 임계 이하의 흐름 조건을 수반하는 유압 점프를 강제합니다. 서로 다른 배출 조건에서 흐름의 거동을 보장하기 위해 채널에 두 개의 세로 줄의 삼각형 블록이 포함되었으며, 이는 정수 조 길이에서 유압 점프를 국지화하기 위해 에너지 소산 기 역할을했습니다. 그 계단의 길이에서 수압 점프. 새로운 변형 채널과 기존 도달 지점(upstream and downstream)사이는 기하학적 요소로 부드럽게 연결합니다.(그림 2).

FLOW-3D Simulations

문제의 정확한 해결을 위해 계산 리소스를 최적화하기 위해 하수도를 여러 개의 중첩 된 범위로 분할하여 수력 솔루션의 연속성을 보장하고 고려 된 각 도달 범위에서 더 미세한 메시를 사용할 수 있습니다. 가장 복잡한 흐름이 정수 조에서 발생하기 때문에 이러한 도달 범위는 윤곽선과 바닥 블록에서 중앙 흐름 영역까지 점진적으로 다양한 셀 크기로 가장 높은 해상도 (6.000.000 셀)로 해결되었습니다. 유압 점프 시뮬레이션에 대한 비디오는 이 기사의 끝에 있습니다.

ke RNG 난류 모델이 선택되었으며, 이류에 대한 명시적인 2 차 단 조성 보존 체계가 있습니다. 자유 표면 표현에는 Split Lagrangian 방법이 사용되었습니다. 정상 상태 솔루션 이전의 과도 흐름은 더 거친 메쉬로 시뮬레이션되었습니다. 그림 3과 4는 수치 시뮬레이션의 관련 결과를 보여줍니다. 또한 수력 점프의 수치 시뮬레이션을 보여주는 비디오 가이드 기술 노트에 첨부되어 있습니다.

유압 점프에서 발생하는 공기 혼입, 특히 난류와 자유 표면 간의 상호 작용을 설명하기 위해 추가 시뮬레이션이 수행되었습니다. 그림 5는 가변 밀도 옵션을 선택하고 기본 계수 C air  = 0.5를 사용하는 FLOW-3D 의 공기 혼입 모델을 사용한 결과를 보여줍니다.

Comparison with the Physical Model

발렌시아 Polytechnic University의 수압 실험실에 실물 모형을 구축하였습니다. 모형에 사용된 척도는 1/20이었습니다. 그림 6은 weir 상단 바로 위에 있는 임계 단면의 프로파일을 보여 줍니다. 발견된 평균 깊이의 오차는 1.3% 였습니다. 유동의 다른 구조적 특성은 FLOW-3D에 의해 적절하게 재현되었다. 예를 들어, 예를 들어, 하수도가 만곡된 범위에 따른 자유 표면의 형상과 Weir의 상류로의 흐르는 자유 표면의 현상입니다.

Conclusions

실험실 결과와 FLOW-3D시뮬레이션 간의 약간의 차이가 확인되지만 연구 결과는 매우 만족스럽습니다. 아래 동영상을 통해 실험 및 수치해석 결과를 비교해 보시길 바랍니다.

FLOW-3D는 가능한 많은 형상 또는 유압 설계를 테스트할 때 실험실의 실험 횟수를 줄일 수 있습니다. 또한 FLOW-3D의 파일이 속도, 와도, 난류 등과 같은 관련 분야의 상세한 시공간 분포를 제공하므로 최종 설계와 관련하여 실험실에서 수행 된 결과와 측정을 확장하는 데 도움이 될 수 있습니다. 결합된 기술은 연구에서 언급한 것과 같은 유압 기반시설의 설계, 검증 및 최적화를 위한 강력한 도구입니다.

침전물 수송에 대한 집중적인 연구는 저수지 관리, 댐 운영 및 하천 내 유압 구조물 설계를 위해 하천의 총 침전물 하중을 예측하는 적절한 방정식이 필요하다는 것을 보여준다.

침전물 운송에서 사용 가능한 어떤 방정식도 총 침전물 운송 속도를 예측하는 데 보편적으로 받아들여지지 않았다. 이러한 사실들은 침전물 수송률을 예측하기 위한 이 모든 공식을 나타내기 위한 일반적인 공식의 필요성을 나타낸다.

본 논문의 첫 번째 목표는 모든 강에 대해 통합된 총 침전물 운송 방정식을 찾는 것이다. 반면, 스퍼다이크나 교각 같은 유압 구조물을 둘러싼 마찰은 구조적 안정성을 약화시키는 심각한 문제가 될 수 있다.

이러한 유압 구조 주변의 난류 흐름장 및 난류 분포에 대한 조사는 국부적 골재 메커니즘의 이해와 국부 침전물 수송에 영향을 미치는 난류 특성을 결정하기 위해 필수적이다.

또한 개방 채널의 난류 흐름의 모든 경우에 유효한 범용 난류 모델은 존재하지 않는다. 본 논문은 일련의 3대 제방 주변의 난류장과 난류 분포를 철저히 조사했다.

목표는 국부 침전물 수송 속도를 예측하기 위한 유의한 난류 특성을 결정하고 제방 주변의 난류 유역 시뮬레이션을 위한 적절한 난류 모델을 식별하는 것이다.

일반적인 통합 총 하중 방정식을 개발하기 위해, 본 연구는 총 침전물 하중을 예측하는 데 일반적으로 사용되는 31개의 공식을 평가한다. 본 연구는 서로 다른 공식에서 침대 전단 응력의 확률적 특성으로 계산된 결과의 편차를 귀인시키고 침대 전단 응력이 로그 정규 분포를 만족한다고 가정한다.

주어진 침대 전단 응력에서 몬테카를로 시뮬레이션이 각 방정식에 적용되고 일련의 침대 전단 응력이 무작위로 생성된다. 모든 방정식의 각 몬테카를로 실현에서 생성된 총 침전물 하중은 모든 방정식에서 예측된 총 침전물 하중의 표본을 나타내기 위해 조립된다. 주어진 각 침대 전단 응력에서 결과적인 총 침전물 하중(예: 표준 편차, 평균)의 통계적 특성이 계산된다.

그런 다음 모든 방정식의 평균 값을 기반으로 통일된 총 침전물 하중 방정식을 구합니다. 결과는 모든 방정식의 평균이 무차원 침대 전단 응력의 검정력 함수임을 보여주었다. 측정과 합당한 합치도는 통합 방정식이 총 침전물 하중을 예측하기 위한 어떤 개별 방정식보다 정확하다는 것을 보여준다.

일련의 스퍼다이크 주변의 흐름장 및 국소적 스컬에 대한 실험 및 수치 시뮬레이션은 고정된 평면 침대 및 스커드 침대 조건에서 수행된다. 마이크로 어쿠스틱 도플러 속도계(ADV)는 세 가지 공간 방향 모두에서 순간 속도 필드를 측정하는 데 사용되며 측정된 속도 프로파일은 난류 특성을 계산하는 데 사용됩니다.

결과는 그 지역의 골칫거리가 첫 번째 제방을 중심으로 발전한다는 것을 보여준다. 난류 강도와 플랫 베드에서 측정한 수직 방향의 평균 속도는 스칼럼 깊이와 밀접한 관련이 있다.

또한 3다이크 시리즈의 두 번째 다이크 끝에서 발생하는 최대 침대 전단 응력은 최대 스콜과 일치하지 않는다.

침대 전단 응력으로 인한 큰 침대 하중 전달은 침대 스쿠싱을 시작하지 않을 수 있지만, 난기류 폭발(예: 스위프 및 배출)은 침대 표면에서 침전물을 끌어들여 국소적 골재를 발생시킨다. 3차원 수치 모델 FLOW-3D는 평평하고 스커드 베드에서 일련의 스퍼다이크 주변의 난류 유량을 시뮬레이션하는 데 사용된다.

본 연구는 Prandtlès의 혼합 길이 모델, 하나의 방정식 모델, 표준 2- 방정식 k-e 모델, RNG(Renormalization-Group) k-e 모델 및 LES(Large Eddy Simulations) 난류 모델을 조사한다. Prandtlès의 혼합 길이 모델과 하나의 방정식 모델은 다이크 주변의 플로우 필드에 적용되지 않는다.

표준 2- 방정식 k-e 모델과 RNG k-난류 모델을 사용한 평균 흐름 필드의 결과는 실험 데이터에 가깝지만, 다른 난류 모델에서 시뮬레이션된 난류 특성은 상당한 차이를 보인다. 다른 난류 모델에서 계산된 결과는 RNG k-e 모델이 이 일련의 스퍼다이크에 대한 평균 흐름 필드를 가장 잘 예측한다는 것을 보여준다.

난류 폐쇄 모델 중 난류 운동 에너지와 같은 난류 특성의 정확한 결과를 예측할 수 있는 모델은 없다. 이러한 결과에 기초하여, 본 연구는 다이크 주변의 평균 흐름 필드를 시뮬레이션하기 위해 RNG k-e 모델을 사용할 것을 권고한다. 다양한 흐름 조건에서 이 일련의 스퍼다이크 근처의 난류 특성을 예측하기 위해 FLOW-3D 모델의 추가 개선이 필요하다.

Abstract

엔지니어링 설계에서 유한 요소, 유한 차분 및 전산 유체 역학 분석 소프트웨어와 같은 수치 도구의 일상적인 사용이 최근 몇 년 동안 증가했습니다. 소프트웨어 및 하드웨어 기술의 발전은보다 비선형적이고 복잡한 3 차원 분석이 수행되고 있음을 의미합니다.

그러나 본질적으로 “블랙 박스”인 이러한 강력한 소프트웨어는 “컴퓨팅”기술을 보유하고 있지만 광범위한 엔지니어링 경험이 필요하지 않은 분석가의 손에 “컴퓨터 보조 재해”로 이어질 수 있습니다. 품질 보증 절차의 엄격한 구현은 수치 모델이나 분석 기법이 정확한지 확인할 필요가 없을 수 있습니다.

이 백서에서는 복잡성이 증가하는 세 가지 실제 토목 공학 응용 프로그램에서 수치 분석 결과를 검증하는 방법을 설명합니다. 여기에는 유한 요소법을 이용한 수조 탱크의 구조 해석, 전산 유체 역학법을 이용한 수력 구조물 위의 홍수 조사, 유한 ​​차분법을 이용한 안벽 시공 시뮬레이션 등이 있습니다. 입력 데이터의 불확실성 수준과 각 사례에 대한 계산 결과의 신뢰성에 대해 논의합니다. 분석 과정에서 몇 가지 흥미로운 결과가 발견되었습니다.

첫 번째 사례 연구는 시공의 질이 구조물의 성능에 상당한 영향을 미친다는 것을 보여주었습니다. 그러나 설계자는 설계 단계에서 이러한 상황을 수량화하고 분석하지 못할 수도 있습니다. 필요할 경우 향후 역분석은 물론 설계 검증의 기준점이 될 수 있도록 공사 종료 시 모니터링의 중요성이 필수적입니다. 유한 요소 분석은 복잡한 문제를 분석할 수 있는 강력한 수치 도구이지만, 분석가들은 문제의 행동이 단순하고 잘 이해되는 것처럼 보일 수 있는 상황에서 예상치 못한 결과를 만날 수 있도록 준비해야 합니다.

두 번째 사례 연구에서는 중요한 배수로 구조에 전산 유체 역학 분석이 처음으로 적용 되었기 때문에 엄격한 검증 프로세스가 강조됩니다. 그것은 2D ogee 방수로 프로파일로 시작하여 문제의 방수로의 3D 모델을 분석하기 위해 진행되는 방식으로 수행되었습니다.
계산된 결과를 각 단계에서 이론 및 물리적 테스트 데이터와 비교했습니다. 유체 흐름 문제의 비선형적 특성에도 불구하고, 분석은 확신을 가지고 실제 설계 목적에 적합한 결과를 제공할 수 있었습니다.

최종 사례 연구에서는 안벽의 거동이 시공 이력과 매립 방식에 영향을 받은 것으로 나타났습니다. 벽의 움직임은 매우 가변적인 토양 속성에도 불구하고 질적으로도 단순한 비선형 토양 모델을 사용하여 정확하게 예측되었습니다. 지속적인 모니터링 기록이 없기 때문에 검증은 어려웠습니다. 계산된 결과를 검증하는 열쇠는 수치 소프트웨어 도구를 사용하지 않는 독립적인 계산을 찾는 것입니다. 대부분의 경우 이러한 솔루션을 사용할 수 있습니다. 그러나 다른 경우에는 실험실 또는 현장 관찰에만 의존할 수 있습니다.

Introduction

오늘날 수치 해석은 대부분의 엔지니어링 설계에서 필수적인 부분을 형성합니다. 따라서 결과 검증의 필요성은 분석 기술 / 방법론을 신뢰할 수 있고 설계자가 계산 된 결과에 대한 확신을 가질 수 있도록 설계 프로세스 전반에 걸쳐 매우 중요합니다.

일반적인 관행은 고전 이론, 실험 데이터, 게시 된 데이터, 유사한 구조의 성능 및 다른 사람이 수행 한 수치 계산에 대해 결과를 검증하는 것입니다. 때때로 소프트웨어 개발자가 제공 한 벤치 마크 또는 검증 예제가 이러한 목적으로 사용될 수 있지만 전체 범위의 문제를 포괄 할만큼 포괄적 인 경우는 거의 없습니다.

수치 해석을 시작하기 전에 분석가는 입력 데이터의 신뢰성, 소프트웨어 도구가 문제의 문제를 해결할 수 있는지 여부 및 결과를 검증하는 방법을 결정해야합니다. 검증 프로세스가 많은 실무자들에 의해 품질 보증 절차의 일부로 채택되었지만 비용이 많이 드는 실패가 여전히 발생했습니다 [1].

Validation

결과 검증의 필요성은 수치 분석의 사용 (남용)에서 일부 나쁜 업계 관행을 관찰함으로써 강화 될 수 있습니다. 수치 계산을 수행하기 위해 고용 된 일부 엔지니어 / 분석가는 계산 뒤에있는 기본 이론을 완전히 이해하지 못하거나 숨겨진 함정을 처리 할 수있는 실제 엔지니어링 경험이 충분하지 않을 수 있습니다.

일부 소프트웨어가 “CAD와 유사”해지고 많은 사람들이 작동하기 쉽다고 주장하기 때문에 엔지니어링 회사가 대학원 엔지니어 대신 초보를 고용하여 수치 모델링 및 분석을 수행하는 경향이 점차 증가하고 있습니다.

사용자는 복잡한 지오메트리 모델을 생성하고, 적절한 요소와 메시를 만들고, 각 하중 케이스에 대한 경계 조건 (접촉, 하중 및 고정)을 적용하고, 속성을 할당하고, 제출에 필요한 모든 플래그 / 스위치 / 버튼을 설정하는 데 상당한 노력을 기울일 것입니다.

분석이 실행됩니다. 자체 검사를위한 일부 품질 보증 절차는 전처리 단계에서 따를 수 있지만 계산이 완료되고 결과가 후 처리 될 때까지 많은 사용자는 출력이 어느 정도 정확하다고 쉽게 믿을 것입니다. 지오메트리 생성은 수치 모델링 프로세스의 일부일뿐입니다. 가장 어려운 문제 중 하나는 전체 설계 프로세스에서 불확실성을 다루는 것입니다. 재료 속성 및 로딩 순서와 같은 입력과 관련된 불확실성이 있습니다.

예를 들어 모델이 선형 또는 비선형 방식으로 동작하는지 여부와 같이 솔루션 유형의 적절성과 관련된 불확실성이 있습니다. 마지막으로 결과 해석과 관련된 불확실성이 있습니다. 수치 분석에서 결과를 검증하고 문제를 발견하는 데있어 분석가를위한 좋은 방법에 대한 간단한 지침은 없습니다. 그러나 다음 방법을 통해 점차적으로 달성 할 수 있습니다.

• 수치 적 방법 과정에 대한 좋은 이해 – 이것은 학부 및 / 또는 대학원 수준의 공식 교육을 통해 얻을 수 있으며 지속적인 전문성 개발의 일환으로 자습을 통해 더욱 향상 될 수 있습니다.
• 특정 유형의 문제에 대한 기본 이론과 해결책의 범위를 잘 이해합니다. 이 역시 위와 같은 교육을 통해 이루어질 수 있습니다.
• 실제 문제를 해결하는 데 공학적 판단을 사용하고 수치 분석을 수행 한 경험이 있습니다. 이는 숙련 된 엔지니어가 분석가를 적절하게 감독하는 환경에서 작업함으로써 얻을 수 있습니다.

품질 보증 시스템의 구현이 실행 가능한 솔루션으로 이어지는 엔지니어링 판단을 대체하는 것은 아니라는 점에 유의해야합니다. 복잡한 대규모 모델을 분석하기 전에 시뮬레이션 기술과 문제의 근본적인 동작을 완전히 이해하기 위해 간단한 테스트 모델을 사용하여 수치 “실험”을 수행해야하는 경우가 매우 많습니다.

경험에 따르면 때때로 테스트 모델 자체가 분석가가 최종 설계 솔루션에 도달 할 수있는 충분한 정보를 제공 할 수 있습니다. 해당 대형 복합 모델의 분석은 설계 기대치를 확인하는 것입니다. 다음 사례 연구는 결과 검증이 수행 된 방법과 신뢰 수준 및 불확실성이 해결된 방법을 보여줍니다.

Applications

일반적인 토목 공학 프로젝트에서 수치 분석은 구조 역학, 기하학 및 유체 역학의 세 가지 기본 분야 중 하나 또는 조합을 포함 할 수 있습니다. 문제의 성격은 토양-구조 상호 작용, 유체-구조 상호 작용 또는 토양-유체 상호 작용 중 하나로 분류 될 수 있습니다.

어떤 경우에는 세 가지 모두를 포함 할 수 있습니다. 잠재적 인 복잡성을 고려하여, 정확도를 잃지 않고 실제 목적을 위해 중요한 동작을 캡처하지 않고 문제를 단순화하기 위해 몇 가지 가정과 이상화가 이루어져야합니다. 이러한 문제를 해결할 수있는 범용 및 특수 수치 분석 소프트웨어가 있습니다. 두 가지 유형의 소프트웨어가 사례 연구에 사용되었습니다.

Case 1 – Deflection of a steel water tank

직경 약 90m의 대형 원형 강철 물 탱크는 처음 채울 때 큰 벽면이 휘어지면서 탱크의 장기적인 구조적 무결성에 대한 우려를 불러 일으켰습니다.

물의 높이는 전체 저장 용량에서 약 10m였습니다. 지붕 구조는 탱크 내부에있는 기둥으로 거의 전적으로지지되었습니다. 스트레이크(strakes)는 벽의 바닥 1/3이 더 두꺼운 고급 강판으로 구성되었습니다. 1 차 윈드 거더는 탱크 상단 주위에 용접되었고 2 차 윈드 거더는베이스 위 2/3에 위치했습니다. 하단 스트레이 크는 환형베이스 플레이트에 필렛 용접되었습니다. 내부 기둥의 기초를 제외한 전체 바닥은 용접 된 강판으로 덮여있었습니다.

이 탱크는 유능한 중간층 사암과 미사암 기반암 위에 압축된 채움물 위에 세워졌습니다. 일련의 축 대칭 유한 요소 분석 (FEA)을 수행하여 관찰된 처짐을 예측할 수 있는지 여부를 결정하고 매일 물을 채우고 비울 때 피로 파괴가 발생할 가능성으로 인해 벽 바닥의 응력 상태를 계산했습니다.

내부 기둥과 지붕 빔을 포함하는 탱크의 12 분의 1 섹터에 대한 3 차원 모델을 처음에 분석하여 벽이 얼마나 많은 지붕 자중을지지하고 축 대칭 가정의 타당성을 조사했는지 조사했습니다. 이 분석의 결과는 지붕 구조의 강성 기여도가 중요하지 않아 후속 축 대칭 모델에 포함되지 않았 음을 보여주었습니다.

그러나 지붕 자체 무게의 작은 부분이 벽에 적용됩니다. 축 대칭 모델은 모든 강철 섹션, 필렛 및 맞대기 용접 및 기초로 구성되었습니다 (그림 1). 그것들은 몇 개의 3 노드 삼각형 축 대칭 요소가있는 4 노드 비 호환 모드 사변형으로 이산화되었습니다.

용접 재료를 통해서만 하중 전달이 허용되도록 용접이 모델링되었습니다. 용접 연결부에 미세한 메시를 사용하여 응력 상태를 정확하게 포착했습니다. 롤러 지지대는 모델의 측면 및 하단 경계에 적용되었습니다. 다음과 같은 하중이 적용되었습니다 :

철골 구조물의 자중, 지붕 자중, 벽의 정수압, 수위에 따른 바닥의 균일 한 압력. 한 모델은 용접 또는베이스의 강판이 플라스틱 힌지를 형성하기 위해 항복되었다고 가정했습니다. 이 경우 벽 바닥에서 핀 연결이 모델링되었습니다.

그림2 Partial FE mesh of tank/foundation. Insert shows mesh and stress distribution at wall base

벽 처짐은 그림 2에 나와 있습니다. 측정 범위와 계산 된 결과는 비교 목적으로 표시됩니다. 계산 된 벽 처짐을 검증하기 위해 두 벽 두께에 대한 Timoshenko 및 Woinowsky-Krieger [2]에 기반한 고전 이론도 그림에 표시되었습니다. 계산 된 편향은 이론적 계산에 의해 제한됨을 관찰 할 수 있습니다.

벽 두께의 변화로 인한 전이가 분석에서 포착되었습니다. 이것은 유한 요소 모델에 대한 확신을 제공했습니다. 윈드 거더와 구속 된베이스의 영향도 볼 수 있습니다. 윈드 거더 설치로 인해 초기 변형이 발생하여 공사가 끝날 때 벽 상단이 안쪽으로 당겨질 수 있습니다. 굽힘 동작이 발생한베이스 근처를 제외하고는 후프 동작이 벽 동작을 지배했습니다.

계산된 최대 처짐이 측정된 순서와 동일하더라도 최대 돌출이 발생한 높이는 예측되지 않았습니다. 실제로 조사 데이터는 몇 가지 가능한 시나리오를 제안했습니다.베이스에 플라스틱 힌지 형성 (그러나이 영역에서 계산 된 응력은 항복 강도를 초과하지 않았습니다). 지반 재료의 국부적 인 베어링 고장 (다시 현장에서 균열과 같은 명백한 지시 신호가 보이지 않음); 또는 탱크 건설이 끝날 때 내장 된 기하학적 결함이있었습니다. 사전 변형 된 탱크에서 역 분석을 수행하여 측정 된 처짐이 정수압 하에서 “회복”되었습니다. 그러나 계산된 응력은 수율을 훨씬 초과했습니다. 불행히도 탱크는 완성 후 첫 번째 충전 전에 즉시 조사되지 않았습니다.

탱크의 원래 디자인과 건설이 2000 년대 초에 수행되었다는 점은 흥미 롭습니다. 설계 계산에 관련 표준 [3]을 사용했습니다. 이 표준은 탱크 벽이 후프 동작만으로 작용한다고 가정하고이 구조의 경우가 아닌베이스의 제약 조건을 무시합니다. 벽 처짐의 크기는 기초 강성을 고려한 Rish [4]가 개발 한 고전 이론 [2] 또는 FEA와 같은 수치 분석에 의해 결정될 수 있습니다. 고급 강철을 사용하면 설계자는 강도에는 적합하지만 서비스 가능성에는 필요하지 않은 더 얇은 섹션을 선택해야합니다. 굽힘 강성은 큐브 두께에 의해 결정됩니다. 수중 부하에서 후속 벽 변형 프로파일은 제작 품질에 영향을받습니다. 이것은 설계 단계에서 추정하기 어려웠을 것입니다.

사례 2 – 배수로 배출

호주의 많은 댐 구조는 제한된 수 문학적 정보로 1950 년대와 60 년대에 설계 및 건설되었습니다. 이러한 기존 방수로 구조는 수정 된 가능한 최대 홍수 수준에 대처하기 위해 크기가 작습니다. 증가 된 홍수 조건 하에서 방수로 꼭대기에 대한 음압 생성과 같은 잠재적 인 문제가 발생할 수 있습니다. 이는 방수로 및 게이트 구조에 불안정성 또는 캐비테이션 손상을 유발할 수 있습니다. 역사적으로 스케일링 된 물리적 모델은 이러한 동작을 연구하기 위해 수력 학 실험실에서 구성되었지만 비용이 많이 들고 시간이 많이 걸리며 스케일링 효과와 관련된 많은 어려움이 있습니다. 오늘날 고성능 컴퓨터와보다 효율적인 전산 유체 역학 (CFD) 코드를 사용하여 수리적 구조의 동작을 합리적인 시간과 비용으로 수치 적으로 조사 할 수 있습니다. 이 분석 기법은 대도시 지역에 주요 상수원을 제공하는 가장 큰 콘크리트 중력 댐에 호주에서 처음으로 적용 되었기 때문에 검증을 수행 할 필요가있었습니다. 이것은 그림 3과 같이 조사 프로세스에 통합되었습니다. 순서도는 간단한 2D에서 상세한 3D 방수로 모델로 어떻게 발전했는지 보여줍니다.

미 육군 공병대 [5]에서 발표 한 광범위한 데이터가 있기 때문에 검증을 위해 ogee 방수로 프로필 (그림 4 참조)이 선택되었습니다. 계산 된 결과는 조사의 각 단계에서 검토되었습니다. 게시 된 데이터에서 크게 벗어나면 프로젝트가 중단됩니다. 이것은 프로젝트가 시작되기 전에 고객과 상호 합의되었습니다.

이러한 종류의 분석의 초기 어려움 중 하나는 개방 채널 중력 흐름 문제에서 자유 표면의 정확한 계산이었습니다. 자유 표면을 추적하는 데 적응 형 메싱 및 반복 방법을 사용하는 것은 일부 유한 체적 CFD 코드에서 사용되었지만 성공은 제한적이었습니다. 본 연구에 사용 된 코드는 SOLA-VOF 방법으로 Navier-Stokes 방정식을 해결합니다. 유체 운동의 과도 동작을 해결하기 위해 유한 차분 방법이 사용되었습니다. 유체의 부피 (VOF) 함수는 자유 표면 운동을 계산하는 데 사용됩니다 [6].

분석에 대한 자세한 내용은 [7]에 설명되어 있습니다. 계산 된 파고 압력 분포, 자유 표면 프로파일 및 정상 상태에서의 배출 속도는 검증 목적으로 사용되었습니다. 다른 상류 수두 (H) 아래의 배수로 꼭대기를 따라 압력 분포가 그림 5에 나와 있습니다. 일부 압력 진동은 코드가 일반 메시와 곡선 배수로 장애물 사이의 인터페이스에서 계산을 처리하는 방식에 기인 할 수 있습니다. 훨씬 더 미세한 메쉬는 이러한 불규칙성을 부드럽게 만들었습니다. 압력 분포에 대한 교각의 영향은 3D 모델에서 올바르게 예측되었습니다 (그림 6).

계산된 자유 표면 프로파일 (그림 7)도 게시 된 데이터와 잘 일치했습니다. Savage와 Johnson [8]은 분석 기법에 대한 신뢰도를 높이는 동일한 CFD 코드를 사용하여 유사한 유효성 검사를 수행했습니다. 문제의 배수로에 대한 후속 분석은 스케일링 된 물리적 모델 테스트에서 얻은 결과와 비교할 때 상당히 좋은 결과를 제공했습니다.

Figure 7 Upper nappe profile next to pier
Figure 7 Upper nappe profile next to pier

분석에서 배수로의 기하학적 구조와 물 속성이 잘 정의되었습니다. 물은 비압축성이며 고정 된 온도에서 일정한 특성을 가지고 있다고 가정했습니다. 실제로 좋은 품질의 콘크리트 표면 마감을 얻을 수 있기 때문에 배수로 경계는 매끄럽다 고 가정했습니다. 불확실성은 메쉬 밀도와 적절한 난류 모델의 선택이라는 두 가지 소스에서 비롯됩니다. 메쉬 크기는 메모리 양과 컴퓨터의 클럭 속도에 의해 제한됩니다.

높은 레이놀즈 수의 난류 흐름은 소용돌이와 소용돌이의 형성을 포착 할 수있는 매우 미세한 메시로 계산할 수 있지만 현재 메시 밀도는 검증 및 설계 목적에 필요한 변수를 예측하기에 충분히 미세했습니다. 조사 결과는 큰 와류, k-ε 및 RNG 모델과 같은 난류 모델의 선택에 의해 크게 영향을받지 않는 것으로 나타났습니다. 분명히 벽 거칠기와 난류 모델의 도입은 방전율을 감소시킬 것입니다. 그러나 다시 분석 결과는 사용 된 메시에 거의 영향을 미치지 않음을 보여줍니다. 향후 분석은 다른 메쉬 밀도로 인한 이산화 오류를 조사 할 것입니다.

사례 3 – 안벽 건설
주요 컨테이너 항구 시설은 설계 단계에서 최소한의 수치 분석을 수행하여 약 25 년 전에 건설되었습니다. 당시에는 이러한 분석 도구를 사용하는 것이 비용 효율적이지 않은 것으로 간주되었습니다. 다수의 컨테이너 크레인이 측면을 따라 이어지는 2km 길이의 안벽을 건설하기 위해 광범위한 준설 및 매립 작업이 수행되었습니다.

시설이 완공 된 이후 일련의 콘크리트 카운터 포트 유닛으로 구성된 안벽과 후방 크레인 빔은 크레인이 할 수 있도록 후방 빔에 대한 레벨 조정 작업이 수행 될 정도로 지속적으로 이동하고 있습니다. 정상적으로 작동합니다. 그러나 영향을받는 두 구조물의 움직임을 저지하기 위해보다 영구적 인 해결책을 모색했습니다. 토양-구조 상호 작용 및 시공 시뮬레이션을 처리 할 수있는 명시 적 유한 차이 분석을 사용하여 다양한 교정 옵션의 순위를 지정했습니다.

그라우트 기둥, 타이백 앵커 및 말뚝 지지대와 같은 다양한 제안 된 개선을 분석하기 전에, 토양 및 구조적 특성과 시공 과정의 선택이 적절하도록 계산 모델을 관찰에 대해 보정해야한다고 결정했습니다. 지질 및 지질 공학 정보는 현장 및 실험실 테스트 데이터를 포함하는 현장 조사 보고서에서 평가되었습니다. 시설의 범위를 고려할 때 현장에서 만나는 특정 토양 유형에 대해 상당한 분산 테스트 데이터가 예상됩니다. 수력 모래 충전재에 대한 표준 침투 테스트 (SPT) 블로우 횟수 (N) 및 콘 침투 테스트 (CPT) 저항 (qc)에 대한 몇 가지 일반적인 기록이 그림 8과 9에 나와 있습니다.

이 결과로부터 평균 해수면 위와 아래에있는 모래 채우기의 강도와 강성의 대비를 관찰 할 수 있습니다. 이 현상은 배치 방법에 기인한다고 제안되었다 [9]. 또한 기초 수준에서 진동 압축 된 모래의 특성에도 변동이있었습니다. 분석을 위해 선택된 토양 특성은 테스트 데이터, 인근 사이트의 경험 및 유사한 토양 조건에 대한 발표 된 데이터를 기반으로합니다. 그것들은 표 1에 요약되어 있습니다. 일반적으로 시설의 건설 순서는 다음과 같습니다.

  1. Removal of pockets of soft marine clay by dredging
  2. Dredging of sand to the required level
  3. Vibro-compaction of the sand on which the counterfort units were to be founded
  4. Placement of gravel for the quay wall foundation.
  5. Placement of concrete counterfort units weighing 360 tonne each
  6. Placement of hydraulic sand fill behind the units
  7. Surcharging the fill just behind the capping beam
  8. Construct capping beam and place more sand fill to the finished level
  9. Additional surcharge prior to the operation of container cranes.

2D 평면 변형 모델의 수치 시뮬레이션에서 구성 순서 (그림 10)와 하중은 다음 단계에 따라 단순화 / 이상적입니다.

  1. The starting condition of the seabed consisted of the vibrocompacted sand, gravel bed, native sand, clay and fissured clay at depth. The “in-situ” stresses were also switched on in this step.
  2. Placement of counterfort unit (using equivalent linear elastic beam elements) with a vertical force applied through the centre of gravity of the unit to represent the buoyant self-weight.
  3. Sequentially placing hydraulic sand fill behind the unit to the level prior to surcharging.
  4. Apply an equivalent trapezoidal pressure to represent the surcharge.
  5. Placement of capping beam and the sand fill to the required level.
  6. Apply additional surcharge.
  7. Application of repeated loads from the crane seaward and landward legs.

분석에서는 침수 된 물질과 평균 해수면 위에있는 물질을 나타 내기 위해 적절한 밀도를 사용했습니다. 안벽의 장기적인 움직임이 중요했기 때문에 배수 된 토양 매개 변수가 사용되었습니다. 토양은 분석에서 Mohr-Coulomb 실패 기준을 따르는 것으로 가정되었습니다. 단순한 탄성-완전 소성 응력-변형 거동이 가정되었습니다. 일련의 강체 다이어그램으로 표현 된 안벽 이동의 역사는 그림 11에 나와 있습니다. 벽의 상단과 바닥에서 계산 된 수직 및 수평 이동은 그림 12와 13에 표시됩니다. 수치는 모니터링 된 데이터와 해당 상한 및 하한 (해당 상자에 표시됨)입니다. 측정에서 산란의 양에도 불구하고 벽 건설에 대해 계산 된 움직임은 합리적으로 잘 비교되었습니다. 조사 데이터와 예측을 일치시키기 위해 분석에서 토양 속성을 변경하려는 시도가 없었습니다. 반복되는 크레인 하중의 래칫 효과를 관찰 할 수 있습니다. 불행히도 반복적 인 크레인 하중 하에서 벽 이동에 대한 기준이 없었기 때문에 이러한 예상 이동을 비교할 수 없었습니다. 문제의 복잡성과 고도로 가변적 인 토양 특성을 고려할 때 계산 된 결과는 매우 고무적입니다.

토양에서 플라스틱 구역의 발달도 분석에서 계산되었습니다. 벽의 발가락 아래의 토양이 여러 번 과도하게 압박을받는 것으로 밝혀졌습니다. 접촉 압력은 경사 하중으로 인한 베어링 고장에 대한 안전 지표 (FOS)를 결정하는 데 사용되었습니다. 지지력은 계산 방법에 의해 크게 영향을 받았다고보고되었습니다 [10]. 원래의 기초 디자인은 덴마크 코드 [11]를 기반으로했기 때문에이 경우 일관성을 위해 사용되었습니다. 편심의 함수로서 FOS의 발전과 수평 대 수직 추력 (H / V)의 비율이 각각 그림 14와 15에 나와 있습니다.

그림은 벽이 추가 요금과 반복적 인 적재 단계 동안 국부적 인 베어링 고장에 가까웠음을 보여줍니다. 크레인 하중 하에서 FOS의 명백한 증가는 벽에 대한 수직 하중이 증가하는 반면 유지된 토양의 수평 압력이 다소 일정하게 유지됨에 따라 편심이 감소했기 때문입니다.

끝 맺는 말
세 가지 매우 다른 실제 응용 프로그램의 유효성 검사 프로세스가 설명되었습니다. 각 사례의 주요 특징과 결과는 표 2에 요약되어 있습니다. 재료 및 하중 불확도 및 예상 결과가 강조 표시됩니다. 건설 품질은 구조의 성능에 상당한 영향을 미치는 것으로 나타났습니다.

이는 분석가가 프로젝트의 설계 단계에서 정량화하고 정확하게 분석하지 못할 수도 있습니다. 구조가 완료된 직후 모니터링의 중요성을 간과해서는 안됩니다. 이것은 미래의 역 분석을위한 유용한 자료가 될 것입니다. 수치 도구가 이러한 복잡한 문제를 분석 할 수 있다는 사실에도 불구하고 분석가는 어떤 매개 변수가 중요하거나 중요하지 않은지 식별 할 준비가되어 있어야합니다.

익숙하지 않은 문제를 분석 할 때 유효성 검사 프로세스를 점진적으로 수행해야합니다. 아마도 검증 방법을 찾는 핵심은 수치 분석 도구를 사용하지 않고 솔루션에 도달 할 수있는 다른 방법이 있는지 묻는 것입니다. 많은 경우 이러한 솔루션은 광범위한 문헌 검색 후에 존재합니다. 그러나 다른 경우에는 실험실 테스트와 현장 관찰이 유일한 대안이 될 것입니다.

원자력 시설물의 잔해물 거동 예측

Debris Transport in a Nuclear Reactor Containment Building

원자로 격리 건물에서 파편 운송

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).

Emergency Core Cooling System (ECCS)

파이프 파손 후 ECCS (비상 코어 냉각 시스템)가 활성화됩니다. 격리 건물 압력을 낮추고 대기에서 방사성 물질을 제거하기 위해 격리 스프레이를 켤 것입니다. 물은 부식 열을 제거하고 용융을 방지하기 위해 코어에 주입됩니다. 이 물은 이후 파이프 파손 부위에서 흘러 나옵니다. 격납 스프레이와 부식 열 제거에서 나온 물은 외부 탱크에서 ECCS 펌프에 의해 격납용기로 펌핑됩니다. 스프레이 및 브레이크 흐름을 통해 격리실로 펌핑된 물의 양은 격리실 바닥에 모이고 풀을 형성합니다.

Sump Strainers and Debris

외부 탱크의 물이 고갈된 후에는 ECCS 펌프에 대한 흡입기가 격납건물 내 하나 이상의 섬프로 전환됩니다(두 개의 섬프 스트레이너 예가 왼쪽에 표시됨). 섬프의 기능은 원자로 건물 풀에서 펌프 흡입구로 물을 재순환하는 것입니다. 각 섬프에는 이물질이 ECCS 펌프로 빨려 들어가 막힘이나 손상이 발생하는 것을 방지하기 위해 스트레이너 시스템이 있습니다. 그러나 스트레이너에 쌓인 이물질로 인해 펌프가 요구하는 순정 흡수헤드(NPSH)를 초과하는 헤드 손실이 발생하여 펌프가 고장을 일으키고 발전소를 안전하게 정지시킬 수 없습니다. 원자력규제위원회 일반안전문제(GSI) 191의 핵심입니다.

FLOW-3D Applied to Evaluate Performance

FLOW-3D는 격납용기 풀을 모델링하고 스트레이너에 도달할 수 있는 이물질의 양을 결정하는 데 사용됩니다. 파이프 파손, 직접 분무 구역(분무기가 비처럼 POOL에 유입되는 지역), 유출 분무 구역(분무수가 더 높은 고도에서 바닥에서 흘러나와 폭포처럼 POOL에 유입되는 지역)은 질량-모멘텀 소스 입자가 밀집된 지역으로 모델링되며, 적절한 유량과 속도가 할당됩니다. 후자는 POOL 표면까지의 자유 낙하 거리에 따라 달라집니다. 여과기 영역은 격납용기 POOL에서 물을 끌어오는 흡입구로 모델링됩니다.

Containment pool simulation

모델을 자유 표면으로 실행하여 (풀의 섬프 흡입 또는 초크 포인트로 인한) 상당한 수위 변화를 식별하고, RNG 모델을 활성화하여 풀의 난류를 예측합니다. 파괴된 절연체가 격납용기 풀을 통해 이동할 수 있는 능력은 정착 속도(정지 상태에서 이동할 수 있는 기능)와 텀블링 속도(바닥을 가로질러 이동할 수 있는 기능)의 기능입니다. 안착 속도는 절연체를 고정하는 데 필요한 운동 에너지의 양과 관련이 있습니다. 이러한 안착 및 텀블링 속도는 연도 및 탱크 테스트를 통해 결정되며, FLOW-3D 모델에 의해 계산된 값입니다.

모델이 정상 상태 상태에 도달한 후에는 FLOW-3D 결과가 후처리되어 다양한 이물질 유형을 POOL 바닥(빨간색으로 표시됨)으로 넘어뜨릴 수 있을 정도로 속도가 높은 영역 또는 난류가 서스펜션의 이물질을 운반할 수 있을 정도로 높은 영역(노란색으로 표시됨)을 결정합니다.

그런 다음 속도 벡터를 빨간색 및 노란색 영역과 함께 사용하여 흐름이 이물질을 스트레이너 쪽으로 운반하는지 여부를 확인합니다. 그런 다음 이러한 영역을 초기 이물질 분포 영역과 비교하여 각 이물질의 유형 및 크기에 대한 운송 분율을 결정합니다.

Conclusions

이물질 잔해 수송 테스트를 CFD 모델링과 결합하면 ECCS 스트레이너가 견딜 수 있어야하는 잔해 부하를 다른 방법으로는 가정해야하는 지나치게 보수적인 값에서 크게 줄일 수 있습니다. CFD는 또한 수두 손실 테스트를 지원하기 위해 ECCS 스트레이너 주변의 흐름 패턴, 수두 손실 테스트 및 플랜트 설계 수정을 식별하는 데있어 격납용 POOL 수위 변화를 식별하는데 유용함이 입증되었습니다.

Wave Energy Devices

파동 에너지 장치 모델링
최근 몇 년 동안 파력 에너지와 같은 재생 가능 자원을 사용하여 환경 영향이 적은 에너지를 생산하는 신기술 개발에 대한 국제적인 관심이 기하 급수적으로 증가했습니다. 바다 (해류, 파도 등)에서 전기를 유도하는 파동 에너지 장치는 특히 중요하며 FLOW-3D로 정확하게 모델링 할 수 있습니다.

포인트 흡수 장치
점 흡수 장치는 수면의 파도를 사용하여 에너지를 생성하는 많은 파도 장치 중 하나입니다. 포인트 흡수 에너지 장치는 기본적으로 파도에서 에너지를 흡수하고 바닥에 대한 부력 상단의 움직임을 전력으로 변환하는 부동 구조입니다.

이 시뮬레이션은 부력 구형 구조가 위에 있는 포인트 흡수기 장치를 보여주고, 들어오는 파동의 파고와 수조에 따라 위아래로 움직입니다. FLOW-3D의 이동 객체 모델은 x 또는 y 방향으로 이동을 제한하면서 z 방향으로 커플링 모션을 허용하는 데 사용됩니다. 스톡스 유형의 파장은 진폭 5m, 파장은 100m로 사용되었습니다. RNG 모델은 파동이 포인트 업소버 장치와 상호작용할 때 발생하는 난류를 포착하기 위해 사용되었습니다. 예상대로, 많은 난류 운동 에너지가 장치 근처에서 생성됩니다. 그림은 난류로 인해 장치 근처의 복잡한 속도장이 진화하기 때문에 질량 중심의 불규칙한 순환 운동을 보여줍니다.

Multi-Flap, Bottom-Hinged Wave Energy Converter

Oscillating flap은 바다의 파동으로부터 에너지를 추출하여 기계 에너지로 변환합니다. 암은 Water wave에 반응하여 피벗 조인트에 장착된 진자로 진동합니다. 플랩을 배열로 구성하여 멀티플랩파 에너지 변환기를 만들 수 있습니다. 3개의 플랩 배열이 아래 왼쪽에 표시된 CFD 시뮬레이션에서 시뮬레이션됩니다. 모든 플랩은 하단에 힌지로 연결되며 폭 15m x 높이 10m x 두께 2m입니다. 어레이는 깊이 30m에서 주파수가 10초인 4m 진폭 파형으로 작동 중입니다. 시뮬레이션은 한 플랩이 배열 내의 다른 플랩에 미치는 영향을 연구하는 데 중요한 중심 평면을 따라 복잡한 속도 ISO 표면을 보여줍니다. 3개의 플랩이 유사한 동적 모션으로 시작하는 동안, 곧 플랩의 상호 작용 효과가 모션을 위상 밖으로 렌더링합니다. 우측에는 유사한 플랩 에너지 변환기가 표시되어 있습니다. 이 시뮬레이션에서 플랩은 가장 낮은 지점에서 완전히 물에 잠깁니다. 이러한 에너지 변환기를 표면 천공 플랩 에너지 변환기라고 합니다. 이 두 시뮬레이션 예는 모두 미네르바 다이내믹스에 의해 제공되었습니다.

Oscillating Water Column

진동하는 물 기둥은 부분적으로 잠긴 속이 빈 구조입니다. 그것은 물의 기둥 위에 공기 기둥을 둘러싸고 수선 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 수있는 터빈을 통해 대기로 흐르게됩니다. 터빈의 회전은 전기를 생성하는 데 사용됩니다.

위의 CFD 시뮬레이션은 진동하는 water columns를 보여줍니다. FLOW-3D로 포착된 물리학을 강조하기 위해 물기둥이 중공 구조에서 상승 및 하강하는 부분만 모델링합니다. 시뮬레이션은 파형 생성의 다른 선택을 제외하고 유사한 결과를 전달합니다. 왼쪽의 시뮬레이션은 웨이브 유형 경계 조건을 사용하고 오른쪽의 시뮬레이션은 움직이는 물체 모델을 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.

Validation of a 3D Dam Breaking Problem

3D 댐 붕괴 문제 검증

이 기사는영국에서 Peter Arnold, Minerva Dynamics, The Guildhall, High Street Bath에 의해 기고되었다.

자유 표면 흐름 시뮬레이션을 위한 FLOW-3D 성능을 평가하기 위해, 장애물 구성이 포함된 3D댐을 검증 사례 중 하나로 선정했습니다. 이 문제는 문서화되어 있으며 ERCOFTAC데이터베이스에서 다운로드할 수 있도록 생성된 모든 실험 데이터를 사용하여 쉽게 설정할 수 있습니다[1]. 장애물은 선박 갑판의 녹색 물에 노출된 컨테이너를 대표하는 것으로 선택됩니다. 실험은 0.55 m의 물을 고정하는 슬라이딩 도어를 가진 대형 탱크 그림 1로 구성됩니다. 도어는 중량 감소에 의해 수직으로 위쪽으로 열리고 물이 방출되어 장애물을 침해한 후 탱크 벽으로부터 3회 반사됩니다. 자유 표면 고도는 탱크 중심선을 따라 4개 위치에서 측정되며 8개의 압력 센서가 장애물의 선행 수직 및 수평 표면에 내장되어 있습니다(그림2). FLOW-3D를 사용한 CFD시뮬레이션은 연속적으로 미세한 메쉬를 사용하여 6초간 실시간으로 수행되었으며 다른 주문 번호 체계와 난류 모델을 사용했습니다.

Figure 1. Snapshot of SPH simulation and experiment at 0.56 secs

시뮬레이션 방법론

시뮬레이션은 3.22mx1mx1.5m 크기의 도메인에 대해 설정되었습니다. 즉, 탱크 지붕에 대한 수직 분사를 허용하기 위해 z방향에서 0.5m 더 큰 도메인이 설정되었습니다. 기본 메쉬는 x-방향의 간격 161개, y-방향 50개, z-방향의 경우 75개가 균일하게 수용되는 육각 셀을 가지고 있었습니다. 장애물 및 센서 위치를 방해하므로 총 약 603,750개의 셀이 사용됩니다. 장애물은 그 영역에 들어갔고 모든 벽은 미끄러짐이 없는 것으로 간주되었습니다. 물의 초기 위치와 점도를 규정한 후, 층류 시간에 의존하는 시뮬레이션을 실시간으로 총 6초 동안 점진적으로 미세화하였습니다. 기본 60cm 셀 메시에서 시작하는 메쉬. 단순히 각 방향의 셀의 수를 2개의 큐브 루트에 의해 증가시킴으로써 각 점진적 메쉬에 대해 총 셀 카운트를 2배 증가시키는 것이었습니다. 이렇게 총 네개의 메쉬가 생겼습니다. 그런 다음 네개의 위치에서 자유 표면 고도의 시간 이력과 여덟개의 압력 센서로부터의 압력을 실험 데이터에 대해 도표로 작성했습니다. CPU와 시뮬레이션의 경과 시간또한 기록되었습니다.

Figure 2. Locations of water height and pressure measurements

기본 메쉬만 사용하여, 추진력 유도에 사용된 수치 구별 계획의 효과를 조사하였습니다. 디폴트가 1st order, 2nd order monotonicity preserving 그리고 3rd order schem이 모두 사용되었으며 결과를 비교했습니다. 또한 single 과 double precision의 효과를 비교하였습니다.

난류 변동은 주로 직접 시뮬레이션을 통해 모델링되었지만 FLOW-3D에서 사용할 수있는 두 가지 난류 모델, 즉 RNG (Renormalization Group) 모델과 LES (Large Eddy Simulations) 모델의 결과도 비교했습니다. 모든 모델은 가장 거칠고 기본 메쉬에서만 실행되었습니다. 메쉬 해상도에 대한 과도한 요구로 인해 탱크 벽에서 가장 가까운 노드의 거리에 대한 일반적인 난기류 모델 관련 제약 조건을 충족시키지 못했습니다.

또한 흐름이 크게 혼란스럽고 장애물이 날카로울 때 흐름 분리 효과의 예측은 점진적인 구분에 의해서가 아닌 기하학적 변화에 의해서 주도될 것입니다. 질서 정연한 경계 층의 변형 따라서, 우리는 경계 층의 분해능이 주 흐름 특성을 예측하는 관점에서 도메인 내부의 흐름을 해결하는 것보다 덜 관련된다고 가정했습니다.

자유 표면 결과

그림 3과 4는 장애물의 상류 위치 H2와 하류 위치 H1에서 시간에 대해 플롯 된 실험 및 계산 된 자유 표면 고도를 보여줍니다. 크기와 타이밍에 약간의 차이가 있지만 주요 기능이 잘 표현되어 있는지 확인하는 것이 좋습니다. 그러나 실험 데이터에는 오류 막대가 제공되지 않으며 혼란스럽고 분리 된 유동장에서 프로브를 사용하여 자유 표면 고도를 측정하는 것은 자유 표면 고도가 문제가 될 수 있다고 말해야합니다. 단일 한 시간 함수가 될 수 없습니다. 이것은 아마도 약 1 초의 초기 가파른 상승 단계에서 H1 높이의 불일치를 설명합니다. 나머지 H1 레코드는 실험과 잘 일치합니다. H2 플롯은 특히 초기 물 상승 단계에서 더 나은 일치를 보여주고 궁극적으로 물의 최대 높이를 잘 예측합니다.

모든 그림에는 실험 뒤에 있는 시뮬레이션의 시간 지연 특징이 있습니다. 차이의 원인은 불분명하지만 시뮬레이션을 통해 점진적으로 도입되는 것으로 보입니다.

압력 센서 결과

그림 5는 시간에 대해 플롯 된 바닥에서 가장 가까운 전면 압력 센서 P1을 보여 주며, 일반적으로 실험과 시뮬레이션 간의 양호한 일치를 나타냅니다. 이 센서는 압력 피크의 도달 거리와 크기를 가장 정확하게 추정합니다. 장애물과 왼쪽 벽에서 물이 튀어 나오면서 신호가 안정되면서 약 2초간 도달할 때까지 압력 신호에 상당한 변동이 있습니다. 그리고 시뮬레이션 값은 실험 값과 잘 일치합니다.

그림 6은 상부 수평 얼굴 압력 센서 P7을 보여 줍니다. 1초에서 2초 사이에 압력 변동이 크므로 시뮬레이션과 실험 데이터가 안정되고 합의가 개선됩니다.

메쉬 수리, 수치 구성 순서 및 난류 모델

메쉬 정밀도의 효과 측면에서 볼 때, 수치 솔루션이 고유한 솔루션으로 수렴되고 있다는 증거는 거의 없는 것으로 보입니다. 난류 모델을 사용하는 대신 직접 시뮬레이션을 통해 유동장의 난류를 모델링 하려고 시도해 왔기 때문에 이는 놀라운 일이 아닐 수 있습니다. 이 접근 방식을 사용하면 메쉬가 미세하게 정제되고 초기 조건에서 섭동에 더 민감해 지기 때문에 흐름 필드에서 보다 상세한 정보를 파악할 수 있을 것으로 예상됩니다. 또한 약간 다른 초기 조건을 가진 많은 시뮬레이션의 평균이 메시 정교함으로 평균화된 솔루션으로 수렴될 것으로 예상합니다. 그러나, 실험에 대한 합의의 수준에 있어서는 35배나 더 오래 걸리는 가장 적은 비용과 가장 비싼 해결책 사이에는 차이가 거의 없습니다. 공학적 관점에서 볼 때, 가장 불리한 메쉬 솔루션은 기본 값이 충분히 정확하고 경과된 시뮬레이션이 단지 15분 이상인 것을 고려할 때 매우 좋은 가치를 나타냅니다.

가속도계 숫자 체계 순서의 효과와 단일 또는 이중 정밀도 산술 실행의 효과는 다음과 같이 요약됩니다. 2차 주문과 3차 주문 계획은 매우 유사한 결과를 보여 주는데, 두가지 모두 실험 곡선을 따르는 것이 더 다양한 1차 주문 계획보다 더 가깝습니다. 또한 상위 순서 방식은 보다 정교한 메쉬의 첫번째 순서 방식보다 코어저 기본 메쉬의 실험 곡선을 따르는 것으로 보입니다. 이중 정밀도 곡선은 단일 정밀도 1차 주문 곡선에서 약간 벗어납니다. 높은 순서도와 이중 정밀도 산술을 사용하는 데 드는 상대적으로 적은 비용을 감안할 때 안정성이 훼손되지 않는다면 향후 계산에서 그렇게 하는 것이 합리적일 것입니다.

난류 변동을 모델링 하는 데 사용되는 방법에 대해서는 각 모델의 실험 시간 이력을 보다 정확하게 예측할 수 있는 능력 면에서 확실한 승자가 없습니다. LES모델의 CPU시간을 더 전통적인 RNG제제와 비교할 때 거의 두 배만큼 층류 모델로써 경제적입니다.

결론

FLOW-3D는 매우 까다로운 자유 표면 유동 문제를 시뮬레이션하는 데 사용되었으며 실험 데이터와 정 성적, 양적 계약을 맺었습니다. 주요 불일치는 종종 고유하지 않은 매개 변수의 자유 표면 높이를 측정하는 데 문제가 있기 때문에 쉽게 발생할 수 있습니다. 흐름이 충돌하는 장애물 표면의 압력 예측은 일반적으로 실험 측정과 잘 일치하며, 주 편차는 실험 측정에서 상당한 양의 변동이있는 곳에서 다시 나타납니다. 실험 측정의 반복성은 문헌에서 논의되지 않았지만 적어도 CFD 시뮬레이션의 차이만큼 클 수있다. 또한 4 개의 프로세서를 통한 공유 메모리 구성에서 약 15 분 내에 난류 모델없이 1 차 차분을 사용하여 비교적 거친 메시에서 솔루션을 적절하게 얻을 수 있음을 확인했습니다. 난류 모델이 필요하지 않다는 것은 결과 흐름을 지배하는 난류 구조가이 수준의 메쉬 미세 조정에서 해석 될 수 있음을 시사합니다.

Aerial Landslide Generated Wave Simulations

Aerial Landslide Generated Wave Simulations

Aerial Landslide Generated Wave(ALGW)는 수역에 영향을 미치는 빠른 슬라이드의 결과이다. 이것은 암석에 의해 생성된 작은 파도 이거나, 3000만 입방 미터의 암석으로 인한 500m를 초과하는 파도 일 수도 있다.
공학적 관점에서 보면 ALGW는 근접한 해안을 따라 인간이 거주하는 인구/자산이 있는 수역에서 발생할 때 큰 관심을 가진다. 여기서 파동이 발생하면 해안선이 파손되고 홍수가 날수 있으며, 댐붕괴로 인한 사망까지 일으킬 수 있다(Müller-Salzburg, 1987). 결과적으로, ALGW에 의해 야기되는 최대 파도 상승을 예측하는 것은 경제적, 환경적, 안전상의 이유로 매우 중요합니다.
안타깝게도 분석적인 솔루션이 없는 매우 복잡한 문제로, 유체 역학적인 측면에서뿐만 아니라 지질학적인 관점(즉, 크기/기하학적인 슬라이드의 밀도 프로파일)에서도 마찬가지입니다. 이와 같이, 대부분의 현장 별 ALGW 최대 파형 예측은 확장된 물리적 모델을 사용하여 평가되었다. 일부는 전산유체역학(CFD) 소프트웨어를 기반으로 할 수도 있지만 비용이 많이 들며, 특히 풀 스케일 3차원 문제의 경우 정확성에 대한 논쟁의 대상이 되고 있습니다.
그러나 컴퓨터 하드웨어와 CFD소프트웨어가 계속 발전함에 따라 이제 CFD를 사용하여 ALGW를 실제로 시뮬레이션할 수 있게 되었습니다. 이와 같이 본 연구는 고 충실도의 물리적 모델 데이터를 FLOW-3D와 비교하여 ALGW를 CFD시뮬레이션을 검증하기 위한 지속적인 노력으로 진척시키는 것을 목표로 한다.
다음 절에서는 실제 및 수치 모델 설정에 대한 개요를 제공한다. 뿐만 아니라, 생성된 데이터와 간단한 비교를 제공한다.

Experimental Setup
물리적 실험은 Northwest Hydraulic Consultants 노스 밴쿠버, 캐나다 실험실에서 만들어졌고 실험을 거쳤다. 그것은 30° 경사의 서쪽 벽을 가진 0.5미터 폭의 수로, 45°의 경사진 동쪽 벽, 그리고 두개의 북쪽과 남쪽 측면에 수직 벽, 그리고 1.025m의 수평 단면을 가진 0.610m 너비의 수로로 구성되었다. ALGW를 생성하고 평가하기 위해, 45° 경사 노즈를 가진 0.177×0.305×0.305m의 아크릴 박스를 사용한 6초 시험을 사용했다.
이 슬라이드를 놓았을 때, 슬라이드는 (중력에 의해) 0.607m 심층수에 충돌하기 전에 서쪽 경사면에서 0.768m 아래로 이동했다. 그 후, 물을 통해 또 다른 1.05m를 이동하여 정지 블록을 치기 시작했다. 슬라이드 가속 및 변위뿐만 아니라 파고 높이는 6 초 실험 전체에 대해 100Hz의 주파수에서 기록되었다. 이 데이터를 수집하는 데 사용 된 도구는 다음과 같다.

  • 컴퓨터화된 데이터 수집 시스템
  • 슬라이드의 시간에 따라 이동 한 거리를 측정하는 문자열 가변 저항기
  • 슬라이드 가속도를 측정하는 1 차원 가속도계
  • 물의 주요 본체 내에 배치 된 3 개의 1 차원 커패시턴스 웨이브 – 프로브
  • 웨이브 런업을 캡처하기 위해 동쪽 경사면을 따라 사용되는 저항 사다리꼴 웨이브 프로브
  • 타이밍 스위치 캡처 슬라이드 릴리스 시간 사용
  • 흑백 비디오 카메라

테스트가 반복 가능하고 오작동이 발생하지 않았는지 확인하기 위해 테스트를 5 번 반복하고 각 장비에 대해 평균을 구했다.

Numerical Model Setup
물리적 실험의 전산화 된 3 차원 모델을 제작한 STL 파일을 FLOW-3D로 가져왔다. 일단 FLOW-3D에 들어간 3D 모델은 약 1,370 만개의 0.0075m 크기의 정사각형 셀로 이산화되었고, 벽을 둘러싸고있는 6 개의면 각각에 ‘wall’경계가 사용되었다.
슬라이드를 일반적인 이동 물체로 설정하고, 물리 모델로부터 수집 된 데이터(즉, 가속 및 변위 데이터의 후 처리)에 기초하여 속도가 주어졌다. 동서면 경사면의 표면 거칠기는 0.00025m으로 설정되었다. 모델링 된 유체는 293k의 물이었고, 동적 RNG 난류 모델이 기본 설정과 함께 사용되었다(implicit pressure solve; and, explicit viscous stress, free surface pressure, advection, moving object/fluid coupling solvers).
물리적 모델과 마찬가지로 FLOW-3D는 6 초의 시간을 시뮬레이트하지만 실제 모델과 같이 매 0.01 초가 아닌 0.02 초마다 데이터를 저장하였다(데이터 관리 관점에서 선택하였음).

Result

FLOW-3D 실험의 결과는 그림에 나와 있다. 4개의 웨이브 각각에 대해 실험 시간 동안 파고를 보여준다. 이와 같이, 제시된 파도 높이는 단순히 flume을 통해 전파되는 파도의 구현(즉, 2 차원의 경우에서 볼 수있는 것)이 아니라 오히려 여러 파도의 상호 작용으로 인한 파도 높이를 초래한다.

  • 슬라이드 충격시 발생하는 충격파(1차 신호)
  • 슬라이드 뒤의 충격파 충돌(2차 신호)
  • 북쪽, 동쪽, 서쪽 및 남쪽 벽에서의 웨이브 반사(3차 신호)

또한 길이 방향의 FLOW-3D 데이터(중심선에서)를 실제 모델 비디오 위에 겹쳐서 자유 표면의 FLOW-3D 글로벌 예측을 평가했다. 이것은 아래의 동영상에서 볼 수 있다.
그림과 위의 비디오를 보면 FLOW-3D 데이터가 웨이브 프로브 1, 2 및 3의 경우 물리적 데이터를 매우 잘 일치한다는 것을 알 수 있다. 하지만 웨이브 프로브 4에 대해서는 정확도가 떨어진다.
FLOW-3D 시간 데이터와 관련된 오류는 각 웨이브 프로브에 대한 RMSE (root-mean-square-error)를 취하여 평가된다.

Discussion
이 조사에서 실제 모델의 고 충실도 데이터는 ALGW로 최대 파도 상승에 대한 FLOW-3D 예측과 비교되었다. RNG 모형의 기본 설정을 사용하여 FLOW-3D는 주요 수역 내에서 파고를 정확하게 재현 할 수 있었다. 그러나 최대 파동은 약 43%가 넘었다.
최대 웨이브 런업을 줄이기 위해 몇 가지 대안인 FLOW-3D 물리 설정이 사용되었다. 그러나 43 % 이하로 떨어지는 것은 불가능했다. 이러한 대체 시뮬레이션에 대한 주목할만한 관찰은 다음과 같다.

  • first-order momentum advection scheme의 0.01m 메쉬는 최대 파동 상승 오차가 96% 인 반면 동일하게 0.0075m 메쉬의 오차는 130%였다. 그러나 second-order로 변경하면 0.01 m 및 0.0075 m 메시의 경우 각각 55% 및 43%의 오차가 발생한다. 또한 메쉬 셀 크기를 0.005m으로 줄이면 80%의 오차가 발생한다.
  • 이 테스트 케이스에서 가장 중요한 매개 변수는 momentum advection scheme이다. 평균적으로 second-order를 사용하면 first-order대비 오차가 약 50% 감소한다.
  • FLOW-3D의 MP 버전을 사용하여 0.005m의 메쉬 셀 크기를 사용해야 한다. 해석 시 CPU 시간은 33 시간이었다. 비교를 위해 FLOW-3D의 SMP 버전은 0.0075m의 메쉬 셀 크기로 시뮬레이션을 실행하는 데 26시간이 필요했지만 MP 버전은 4.5시간 밖에 걸리지 않았다.

[1] 3.5GHz 8 코어 AMD FX-8320 프로세서에서 약 6초의 시뮬레이션 시간이 대략 26시간 소요되었다.

방파제의 설계는 복잡한 자연 시스템 (바다와 해안)과 인공 구조물 (방파제)의 상호 작용에 대한 완전한 이해가 필요합니다. 일반적으로 설계 작업은 광범위한 물리적 모델링을 수반하므로 비용이 많이 들고 시간이 오래 걸릴 수 있습니다. 최근까지 방파제의 복잡한 측면은 상세한 수치 시뮬레이션에 너무 어려웠습니다. 이것은 물이 비정상적인 동작으로 복잡한 경로를 통해 흐르는 콘크리트 또는 암석 블록으로 구성된 방파제의 경우 특히 그렇습니다.

컴퓨팅 기술의 진보로 수치, 물리적 조사 간의 격차가 좁혀졌습니다. 상호 작용하는 개별 블록으로 구성된 견고한 구조를 정확하게 표현할 수 있으므로 블록 사이의 빈 공간 내에 수치적으로 유동 영역을 생성 할 수 있습니다. 이것은 방류수가 균일한 다공성 매질로 근사되는 Classical Darcy 주제에 고려될 수 없는 대류항 및 난류의 영향을 포함한 전체 유체 역학적 거동의 영향을 평가할 수 있게 합니다

방파제는 물에 잠기거나 잠긴 경우에는 문헌에 나와 있는 표준 실험식을 사용하여 크기를 결정하고 실제 기하학적 패턴을 따르는 전체 크기, 구조 및 물리적 모델링과 같이 수치적으로 구성했습니다 (그림. 2).

제안된 절차의 품질을 검증하기 위해 침수된 방파제에 대해 세 가지 기하학적 구조를 고려했다. 즉, 부유, 다공성, 고형물과 부유물(그림 2a)이 출현한 방파제의 경우, 두 가지 다른 기하학적 구조를 사용했다(Fig. 2b – 2c).

방파제가 결정되면 기하학적 구조을 FLOW-3D로 가져 와서 유체 역학적 작용을 평가 및 Wave propagation의 연구를 위해 테스트했습니다. 시뮬레이션은 RNG 난류 모델과 coarse격자 안쪽에 중첩된 미세한 격자가 있는 전산메쉬를 사용하여 Navier-Stokes 방정식을 3 차원으로 통합하여 수행되었습니다.

수중 장벽 (계산 영역: 90 × 1.9 × 6.5m)의 경우, 포함된 메쉬 블록은 동일한 크기 (0.30 × 0.27 × 0.30m)의 46,200 개의 요소로 구성되며 중첩된 블록은 2,353,412 개의 요소로 구성하였습니다(0.061 × 0.055 × 0.061m).

방파제에도 동일한 기준이 적용되었습니다. 포함된 격자 블록은 150,000개의 요소(0.50×0.20×0.30m)로 구성되며, 중첩된 블록은 2,025,000개의 요소(0.10× 0.10×0.10m)로 생성되었습니다.

결과 중 일부는 다음 이미지에 요약되어 있습니다. 그림 4에서 3 차원 영역의 2 차원 단면을 따른 압력 및 난류 에너지가 나타납니다. 그림 5에는 서로 다른 순간에 잡힌 자유 표면의 3 차원 형상이 나타나있습니다.

유동경로를 따라 개별 솔리드 요소의 윤곽의 유체 역학에 의한 유동 변화는 쉽게 검출 가능합니다. 이것은 자유 표면의 3 차원 재구성에서 가장 잘 드러나며 (그림 5) 방파제에 대한 파동 작용의 효과가보다 자세하게 표현됩니다.

Conclusions

잠수함이나 해상 구조물 간의 상호 작용을 정확히 표현하기 위한 Navier-Stoke기반 수치 시뮬레이션을 활용한 방법, 그리고 유체 움직임이 입증되었습니다. 시뮬레이션은 난류 시뮬레이션을 위한 RANS와 자유 표면 계산을 포함하는 첨단 컴퓨터 유체 동적 소프트웨어 시스템(FLOW-3D)을 사용하여 수행되었습니다.

이 결과는 블록 사이의 경로 내에서 유체 운동의 상세한 그림을 제공함으로써 기존의 흐름 방법보다 더 정확한 시뮬레이션을 제공함을 보여줍니다. 블록을 사용하여 기존의 누설 흐름 방법보다 더 정확한 시뮬레이션을 제공합니다. 원칙적으로 모든 관련 부품(필터, 코어 및 토우)에서 구조물이 물에 잠기거나 나타나는 경우 시뮬레이션이 가능하며 제한은 없습니다.

Further studies will be aimed at assessing the stability of individual blocks through the use of the Moving Object model in FLOW-3D.

환경적 배출 및 유출 구조는 전통적으로 복잡하고 비용 집약적이며 시간이 많이 소요되는 실험 연구를 통해 설계되었습니다. 일체형 접근 방식에 기초한 일부 모델은 제한 사항에도 불구하고 일반적으로 사용되지만 오염 물질 재투입 또는 강한 역효과를 초래하는 방출은 그러한 모델의 가설 밖에 있습니다. 따라서 오염 물질 확산을 위해 전체 3D모델을 사용하면 강과 강 어귀의 실제 오염 물질 분산에 대한 이해를 향상시킬 수 있습니다. 마찬가지로 전체 환경 수질 및 생물학적 조건을 개선하기 위해 경계면의 제트를 모델링과 다른 위치점을 테스트할 수 있다.

본 연구에서는 제트방전을 실험적 및 수치적으로 모델링 합니다. 그리고 전단 영역에서 난류분산의 추정치를 얻을 수 있습니다. 난류 모델링의 경우 k-ε RNG 모델은 자유표면 추적을 위한 VOF방법과 함께 사용됩니다. 난류 운송의 적절한 모델링을 보장하는 오염물질 유도를 위해 단일상태의 2차 압력식이 사용됩니다. 업스트림흐름은 제트를 변형하여 재순환이 일어나는 측면 groin필드로 미는 것이 관찰됩니다. FLOW-3D와 함께 물리적 인 모델링은 난류의 슈미트 수를 얻는데 사용되며, 이것은 강과 같은 유사한 오염 물질 분산 문제에 대해 FLOW-3D에서 사용될 수 있습니다. 경계가 있는 제트는 통계적으로 안정된 최종 솔루션의 경우에도 비정상적인 동작을 보여줍니다. 시각화를 쉽게 하기위해 오염 물질이 도달하는 범위를 나타내는 두 개의 등 농도면 (적색)과 (투명 흰색)이 표시됩니다. 결과적으로, 백색 iso-concentration 표면은 붉은 입자보다 더 큰 분산을 보여 주며, 후자는 첫 번째 표면 내에 완전히 포함되어있다. 이러한 경계의 선택은 실험실에서 사용되는 것과 유사한 방식으로 오염 물질 분산을 가시화 할 수 있게 해줍니다. 격자 간격은 실험 모델에서와 같이 5cm로 설정됩니다. 자연 환경에서 볼 수 있듯이, 제트 배출은 난기류이며 일시적인 평균화와 같은 몇 가지 후 처리 작업이 필요합니다.

수치 모델은 전단영역에서의 제트궤도와 충동에 대해 정확히 재현합니다. 전단 영역에서 흐르는 진동의 주파수는 groin 필드의 전반적인 재순환역학과 관련된 실험모델과 일치합니다. 시뮬레이션을 사용하여 이 흐름 구성에 적합한 슈미트 번호를 결정하고 난류 분산을 정확하게 포착할 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

중력 및 비 관성 기준 프레임 모델에서 시간 함수로서의 무게 중심의 위치는 외부 파일의 표로 정의할 수 있습니다. 이 기능은 연료를 소모하는 로켓을 모델링하고 단계를 분리할 때 유용합니다.

공기 유입 모델

가장 간단한 부피 기반 공기 유입 모델 옵션이 기존 질량 기반 모델로 대체되었습니다.  질량 기반 모델은 부피와 달리 주변 유체 압력에 따라 부피가 변화하는 동안 흡입된 공기량이 보존되기 때문에 물리학적 모델입니다.

Air entrainment model in FLOW-3D v12.0

Tracer diffusion / 트레이서 확산

유동 표면에서 생성된 추적 물질은 분자 및 난류 확산 과정에 의해 확산될 수 있으며, 예를 들어 실제 오염 물질의 거동을 모방합니다.

모델 설정

시뮬레이션 단위

이제 온도를 포함하여 단위계 시스템을 완전히 정의해야 합니다. 표준 단위 시스템이 제공됩니다. 또한 사용자는 선택한 옵션에서 질량, 시간 및 길이 단위를 정의하여 편리하며, 사용자 정의된 단위를 사용할 수 있습니다. 사용자는 또한 압력이 게이지 단위로 정의되는지 절대 단위로 정의되는지 여부를 지정해야 합니다. 기본 시뮬레이션 단위는 Preferences(기본 설정)에서 설정할 수 있습니다. 단위를 완벽하게 정의하면 FLOW-3D는 물리적 수량에 대한 기본 값을 정의하고 범용 상수를 설정할 수 있으므로 사용자가 필요로 하는 작업량을 최소화할 수 있습니다.

Shallow water model

천수(shallow water) 모델에서 매닝의 거칠기

Manning의 거칠기 계수는 지형 표면의 전단 응력 평가를 위해 천수(shallow water) 모델에서 구현되었습니다. 표면 결함의 크기를 기반으로 기존 거칠기 모델을 보완하며이 모델과 함께 사용할 수 있습니다. 표준 거칠기와 마찬가지로 매닝 계수는 구성 요소 또는 하위 구성 요소의 속성이거나 지형 래스터 데이터 세트에서 가져올 수 있습니다.

메시 생성

하단 및 상단 경계 좌표의 정의만으로 수직 방향의 메시 설정이 단순화되었습니다.

구성 요소 변환

사용자는 이제 여러 하위 구성 요소로 구성된 구성 요소에 회전, 변환 및 스케일링 변환을 적용하여 복잡한 형상 어셈블리 설정 프로세스를 단순화 할 수 있습니다. GMO (General Moving Object) 구성 요소의 경우, 이러한 변환을 구성 요소의 대칭 축과 정렬되도록 신체에 맞는 좌표계에 적용 할 수 있습니다.

런타임시 스레드 수 변경

시뮬레이션 중에 솔버가 사용하는 스레드 수를 변경하는 기능이 런타임 옵션 대화 상자에 추가되어 사용 가능한 스레드를 추가하거나 다른 태스크에 자원이 필요한 경우 스레드 수를 줄일 수 있습니다.

프로브 제어 열원

활성 시뮬레이션 제어가 형상 구성 요소와 관련된 heat sources로 확장되었습니다.  history probes로 열 방출을 제어 할 수 있습니다.

소스에서 시간에 따른 온도

질량 및 질량/모멘트 소스의 유체 온도는 이제 테이블 입력을 사용하여 시간의 함수로 정의 할 수 있습니다.

방사율 계수

공극으로의 복사 열 전달을위한 방사율 계수는 이제 사용자가 방사율과 스테판-볼츠만 상수를 지정하도록 요구하지 않고 직접 정의됩니다. 후자는 이제 단위 시스템을 기반으로 솔버에 의해 자동으로 설정됩니다.

데이터를 처리하는 데 걸리는 시간 때문에 큰 지오 메트리 데이터를 처리하는 것은 수고스러울 수 있습니다. 대형 지오 메트리 데이터를 처리하는 데는 여전히 상당한 시간이 걸릴 수 있지만, FLOW-3D는 이제 이러한 대규모 데이터 세트를 백그라운드 작업으로 로드하여 사용자가 데이터를 처리하는 동안 완전히 응답하고 중단 없는 인터페이스에서 작업을 계속할 수 있습니다

난류 / Turbulence

난류 / Turbulence

FLOW-3D 는 완전 3 차원 유동, 2 차원 깊이 평균 (천수(shallow water)) 흐름 및 3 차원/2 차원 깊이 혼합 평균 흐름을 위한 포괄적인 난류 모델링 제품군을 제공합니다.

그림1. 부두 하류에서의 와류 검출을위한 Q- 기준의 3D지도

FLOW-3D 에는 8 가지 난기류 옵션이 있습니다.

  • Prandtl 혼합 길이 모델은 3 차원 난류 효과를 설명하기 위한 가장 초기의 시도 중 하나입니다. 가장 복잡한 모델이 아니며 더 이상 널리 사용되지 않습니다. FLOW-3D 는 주로 학술 연구에서의 유용성을 포함합니다.
  • 소위 1 방정식 모델은 난기류를 나타내는 초기 노력이기도 합니다. 시간 평균 난류 운동 에너지 k를 계산하고 모든 위치에서 알려진 난류 혼합 길이 LT 가 필요합니다. LT 는 일반적으로 미리 알려지지 않기 때문에, one-equation 모델은 복잡한 유량을 모델링하는 데 적합하지 않습니다.
  • 표준 k-ε 모델 (Harlow & Nakayama 1967)은 난류 운동 에너지 k와 소산 속도 ε를 계산하고 난류 혼합 길이 LT를 동적으로 찾는 2 방정식 모델입니다. 이것은 업계 표준이며 광범위한 흐름을 표현하는데 유용하다는 것이 발견되었습니다 (Rodi 1980).
  • 재 정규화 그룹 (RNG) k-ε 모델 (Yakhot & Orszag 1986, Yakhot & Smith 1992)은 2 방정식 k-ε 모델의 보다 견고한 버전이며, 대부분의 산업에서의 문제에 권장됩니다. 표준 k-ε 모델의 기능을 확장하여 과도기 난류, 곡선 흐름, 벽 열 전달 및 물질 전달의 더 나은 적용 범위를 제공합니다.
  • k-ω 2 방정식 모델 (Wilcox 1988, 1998, 2008)은 두 번째 변수를 난류 소산 ε이 아니라 ω ≡ ε / k로 정의한다 (Kolmogorov 1942). Wilcox는 1988 년부터 k-ω 2 방정식 모델을 개선했으며 1998 년에는 자유 전단 유동에 대한 모델의 정확성을 크게 개선 한 새로운 계수를 도입했습니다. FLOW-3D 의 k-ω 2 방정식 모델은 제트, 후류 및 플럼을 퍼 뜨리는 것과 같은 유선형 압력 구배를 갖는 자유 전단 흐름을 모델링하는 데 적합합니다.
    LES 모델은 평균 난류 운동 에너지를 나타내기 위해 스칼라를 사용하지 않고 대부분의 난류 변동을 직접 해결합니다. 그것은 2 방정식 모델보다 훨씬 더 미세한 메쉬 해상도를 필요로하며 난기류에 대한 보다 광범위한 통계를 제공합니다.
  • 2-D 심도 평균 얕은물 난류 모델은 대수적인 완전 난류 속도를 가정합니다. 첫 번째 옵션은 일정한 항력 계수 CD를 가정하며, 이는 공간적으로 변화 할 수 있습니다.
  • 두 번째 2-D 심도 평균 천수(shallow water) 난류 모델은 항력 계수 CD 를 유체 깊이와 공간적으로 가변되는 표면 거칠기의 동적 함수로 만듭니다.

완전한 3-D 테스트를 통해 LES 모델 출력을 시간 평균화하면 2 방정식 Reynolds REN (Reynolds Averaged Navier-Stokes) 모델 (표준 k-ε, RNG k-ε 및 k- ω).

아래의 물고기 통로 비디오에 나와 있습니다.

난류 시뮬레이션 – 모델 비교 / Turbulence Simulations – A Model Comparison

첫 번째 비디오에서는 FLOW-3D 의 LES (Large-Eddy Simulation) 난류 모델을 사용하여 어류 통과를 시뮬레이션하여 속도 변동의 크기를 분석합니다. 두 번째 비디오는 동일한 시뮬레이션의 시간 평균 결과를 보여줍니다. 여기에서 간단한 사용자 정의는 시간 평균 LES가 레이놀즈 평균 Navier-Stokes (RANS) 난류 모델 결과와 매우 유사하다는 것을 보여줍니다. 세 번째 비디오는 RNG (Renormalized Group) k-ε 난류 모델을 사용하여 시연하기 위해 동일한 시뮬레이션을 사용합니다. RNG k-ε 모델은 대부분의 레이놀즈 평균 Navier-Stokes (RANS) 난류 모델과 마찬가지로 속도 변동을 등방성 스칼라 값으로 처리하여 시간에 따른 속도 변동을 감쇠시킵니다. 결과는 두 번째 비디오에서 볼 수 있듯이 직접 LES 결과를 시간 평균하여 찾은 결과와 유사합니다.

FSR_01-12_Air-Entrainment-Report [공기 혼입 모델 분석]

Overview
In free-surface flows the turbulence in the liquid may be sufficient to disturb the surface to the point of entraining air into the flow. This process is important, for example, in water treatment where air is needed to sustain microorganisms for water purification and in rivers and streams for sustaining a healthy fish population. Air entrainment is typically engineered into spillways downstream of hydropower plants to reduce the possibility of cavitation damage at the base of the spillway. Situations where air entrainment is undesirable are in the sprue and runner systems used by metal casters, and in the filling of liquid containers used for consumer products.
The importance of being able to predict the amount and distribution of entrained air at a free liquid surface has led to the development of a unique model in FLOW-3D®. The model has two options. One option, to be used when the volume fraction of entrained air is relatively low, uses a passive scalar variable to record and transport the air volume fraction. This model is passive in that it does not alter the dynamics of the flow.
The second air-entrainment model option is based on a variable density formulation. This model includes the “bulking” of fluid volume by the addition of air and the buoyancy effects associated with entrained air. This dynamically coupled model cannot, however, be used in conjunction with heat transport and natural (thermal) convection.
In addition, when using the variable density formulation, the model can include a relative drifting of air in water, the possible escape of air if it rises to the surface of the water and the removal or addition of air to trapped bubble regions represented as adiabatic bubbles.
The same basic entrainment process is used in both options. It is based on a competition between the stabilizing forces of gravity and surface tension and the destabilizing effects of surface turbulence.
Because turbulence is the main cause of entrainment, a turbulence-transport model must be used in connection with the air-entrainment model. It is recommended that the RNG version of the more traditional k-epsilon turbulence model be employed. All the validation tests reported in this Technical Note were performed using the RNG model.

Turbulent Flow Over a Backward-Facing Step Using the RNG Model

Abstract
Turbulent flow over a backward-facing step is one of the classical tests to validate turbulence models in CFD. In the present work, steady-state turbulent flow over a backward-facing step was simulated using FLOW-3D1 with the Renormalization-group (RNG) k-ε model to account for turbulent viscosity. The Reynolds number was computed using the step height h and the inlet free-stream velocity. The test case was run for two different Reynolds numbers: Reh=5100 and Reh=44,000.

The numerical predictions were compared with the experimental results with the same flow configuration. Streamwise velocity profiles at different locations in the flow direction were in good agreement both qualitatively and quantitatively with the experimental results.

One of the main objectives of this work is to study the sensitivity of the results to the turbulent mixing length parameter tlen in the RNG model. The steady-state velocity was used to compute the reattachment length behind the step for different values of tlen and compared with experimental data. A grid refinement study was performed to find the least mesh resolution needed to capture the essential flow physics of the problem.

Modeling Turbulent Entrainment of Air at a Free Surface

Overview
In free-surface flows the turbulence in the liquid may be sufficient to disturb the surface to the point of entraining air into the flow. This process is important, for example, in water treatment where air is needed to sustain microorganisms for water purification and in rivers and streams for sustaining a healthy fish population. Air entrainment is typically engineered into spillways downstream of hydropower plants to reduce the possibility of cavitation damage at the base of the spillway. Other situations where air entrainment is undesirable are in the sprue and runner systems used by metal casters, and in the filling of liquid containers used for consumer products.
The importance of being able to predict the amount and distribution of entrained air at a free liquid surface has led to the development of a unique model that can be easily inserted into FLOW-3D® as a user customization. The model has two options. One option, to be used when the volume fraction of entrained air is relatively low, uses a scalar variable to record the air volume fraction. This model is passive in that it does not alter the dynamics of the flow.
A second air-entrainment model, option two, is based on a variable density formulation. This model includes the “bulking” of fluid volume by the addition of air and the buoyancy effects associated with entrained air. However, this dynamically coupled model cannot be used in connection with heat transport and natural (thermal) convection.
In both model options the same basic entrainment process is used that is based on a competition between the stabilizing forces of gravity and surface tension and the destabilizing effects of surface turbulence. The model is described in the next section. Because turbulence is the main cause of entrainment, a turbulence-transport model must be used in connection with the air-entrainment model (i.e., ifvis=3 or 4). It is recommended that the RNG version of the more traditional k-epsilon turbulence model be employed. All the validation tests reported in this Technical Note were performed using the RNG turbulence model.

Free Surface Fluid Flow | 자유 표면 유체 흐름

Free Surface Fluid Flow

유체 흐름 문제는 복잡한 기하학적 구조의 자유 표면과 관련되는 경우가 많으며 대부분 매우 일시적입니다. 수력학의 예로는 배수로, 강, 교각 주변, 홍수 범람, 수문, 잠금 장치 및 다수의 기타 구조물의 흐름이 있습니다. 이러한 유형의 흐름을 계산적으로 모델링 하는 능력은 이러한 계산이 정확하고 합리적인 계산 자원으로 수행될 수 있다면 매력적입니다. 유용하게 사용하려면 시뮬레이션은 물리적 모델을 사용하는 것보다 훨씬 빠르고 저렴해야 합니다.

Fluid flow problems often involve free surfaces in complex geometry and in many cases are highly transient. Examples in hydraulics are flows over spillways, in rivers, around bridge pilings, flood overflows, flows in sluices, locks, and a host of other structures. A capability to computationally model these types of flows is attractive if such computations can be done accurately and with reasonable computational resources. To be useful, simulations should be much faster and less expensive than using physical models.

많은 컴퓨터 프로그램은 유체의 역학을 설명하는 편미분 방정식을 풀 수 있습니다. 시뮬레이션에 자유 표면을 포함 할 수있는 프로그램은 많지 않습니다.  그 이유는 Free Surface 경계 문제로 잘 알려진 수학적인 문제입니다.  자유 경계 문제는 다루기 어려운 표면이 이동함에 따라 계산 영역이 변화하는 한편, 그 표면 이동 자체가 계산에 의해 결정된다는 점에 있습니다.  계산 영역의 변화는 그 크기와 모양의 변화뿐만 아니라, 경우에 따라서는 영역의 결합과 분리(즉, 자유 표면의 발생과 소멸)을 포함합니다.

Many computer programs can solve the partial differential equations describing the dynamics of fluids. Not many programs are capable of including free surfaces in their simulations. The difficulty is a classical mathematical one often referred to as the free-boundary problem. A free boundary poses the difficulty that on the one hand the solution region changes when its surface moves, and on the other hand, the motion of the surface is in turn determined by the solution. Changes in the solution region include not only changes in size and shape, but in some cases, may also include the coalescence and break up of regions (i.e., the loss and gain of free surfaces).

이 책에서는 모든 자유 표면을 고려한 유체흐름 현상을 수치 해석용으로 모델링하는 방법에 대해 설명합니다.  이 기술은 VOF (Volume-of-Fluid) 법에 근거한 것으로, 특히 자유 표면 흐름에 적합한 다양한 기능을 제공합니다.  이 책에서는 VOF 법이 자유 표면과 그 발생과 소멸을 해석하는데 가장 자연스럽고 매우 효율적인 방법을 제시합니다.

In this note a computational modeling technique for fluid flows with arbitrary free surfaces is discussed. The technique is based on the Volume-of-Fluid (VOF) technique. This technique has many unique properties that make it especially applicable to flows having free surfaces. The goal of this discussion is to show why the VOF approach offers a natural way to capture free surfaces and their evolution with great efficiency.

VOF 법의 특징을 잘 보여주기 위해 간단하지만 매우 중요한 유동 현상에 관한 문제를 다룹니다.  여기에서는 계단 낙차형상의 낙하류를 예로 들어 있습니다.  개념적으로 간단한 흐름인 동시에 결과의 타당성을 확인하기위한 좋은 실험 데이터도 제공되어 있습니다 (N. Rajaratnam and MR Chamani “Energy Loss at Drops”J. Hydraulic Res. Vol. 33 p.373,1995 참조).

A good recommendation for the VOF method is to demonstrate its capabilities on a simple hydraulic flow problem, one that is far from trivial. The example selected is of flow over a step. This flow has conceptual simplicity and good experimental data available for validation (see N. Rajaratnam and M.R. Chamani, “Energy Loss at Drops,” J. Hydraulic Res. Vol. 33, p.373, 1995).

Prototype Hydraulic Flow with Free Surfaces

그림 1a는 정상 상태에 도달 한 후 흐름의 문제를 보여줍니다.  계단 낙차형상 상부로부터의 월류(액체 또는 스냅 시트)에는 상하 모두의 자유 표면이 있습니다.  월류의 아래쪽에는 월류와 계단 가공면 사이에 웅덩이가 형성되어 있으며, 하류에서는 액체는 평평한 정상 표면에서 오른쪽으로 흐르고 있습니다.  엄밀히 말하면, 웅덩이 영역의 흐름 상태는 정상입니다.  이것은 충돌하는 액체에 의해 풀에 난류 혼합이 발생하고 있기 때문입니다.  그러나 평균적인 구성이 존재하고 그것은 실험에서도 보고됩니다.

Figure 1a shows the flow problem after it has reached a steady-state condition. The overflow (sheet of liquid or nappe) leaving the top of the step has both an upper and lower free surface. At the bottom of the overflow a pool has formed between the overflow and the face of the step, while downstream, liquid is flowing to the right with a flat, steady surface. Strictly speaking, the flow conditions in the pool region are not steady because turbulent mixing is generated in the pool by the impinging fluid. There is, however, an average configuration and that is what is reported in the experiments.

실용적인 목적 유동 흐름은 항상 2 차원입니다.  즉, 그림 1a에서 수직 방향에서는 큰 변화는 없습니다.  현실에서는 웅덩이 위쪽으로 공간을 만들기 위해서는 대기에 여유공간이 필요하고, 그게 없으면 닫힐 것입니다.

For all practical purposes the flow is two-dimensional, that is, it does not have any significant variation in the direction normal to the illustration in Fig. 1a. In actuality, to have an air space above the pool there must be some opening to the atmosphere otherwise it would close up.

계단 낙차형상 상단의 유속은 중요합니다.  즉, 이것은 표면파와 같거나 그 이상의 속도이기 때문에 하류에서의 교란이 영역을 관통하고 상류 흐름 (계단 낙차형상의 왼쪽)에 영향을 줄 수 없습니다.  따라서 이 영역에서의 흐름은 예외적으로 원활하고 정상입니다.

The flow speed at the top of the step is critical, that is, it has a speed equal to or greater than the speed of surface waves, so that no disturbances from downstream can penetrate through this region to affect flow upstream (to the left of the step), which is why the flow is exceptionally smooth and steady in that region.

이 문제는 수치 시뮬레이션과 비교할 수 있는 기하 형상 기능이 많이 있습니다.  예를 들어, 계단 낙차형상의 전후 흐름의 높이, 월류가 바닥에 충돌 할 때의 각도, 월류 아래에 형성되는 웅덩이의 깊이 등입니다.  또한 실용화를 위한 중요한 비교 항목으로는, 계단 낙차형상을 통해 떨어지는 낙하 류에 의해 손실되는 에너지의 양 (운동 에너지와 위치 에너지의 합)가 있습니다.

There are many geometric features in this problem that can be compared with a numerical simulation; such as flow heights before and after the step, the angle of the overflow stream when it strikes the bottom and the depth of the pool formed under the overflow. Additionally, an important comparison for practical applications is the amount of energy (i.e., kinetic plus potential) lost by the flow in passing over the step.

Simulation of Prototype Problem

그림 1a는 시뮬레이션의 결과입니다.  이 예에서는 실험에 사용된 모든 기하 형상 및 물질의 특성이 시뮬레이션에 사용되었습니다.  실험실 테스트에서 사용한 계단 낙차형상의 높이가 62cm에서 액체는 보통의 물 (밀도 = 1.0gm / cc 어떻게 점성 = 0.01dynes / cm)입니다.  계산 영역에 들어가는 물의 깊이는 15.5cm에서 속도가 임계에 가까운 123.0cm/s 였습니다.  물론, 중력은 수직 방향으로 크기는 g = -980cm / s^2입니다.

Figure 1a is from a simulation. For this example all of the geometric and material properties used in the experiments were used in the simulation. The height of the step used in the laboratory test is 62cm and the fluid is ordinary water (density=1.0 gm/cc and dynamic viscosity=0.01dynes/cm). The depth of water entering the computational region was 15.5cm and was given a near critical velocity of 123.0cm/s. Of course, gravity was in the vertical direction with magnitude g=-980cm/s^2.

월류 왼쪽에 있는 웅덩이에 난류가 발생 할 것으로 예상 되었기 때문에, 시뮬레이션에서는 난류 모델 (the Renormalization Group, 즉 RNG 모델)을 사용했습니다.  그 후, 난류 모델을 사용하지 않고 한 시뮬레이션에서도 비슷한 결과를 얻을 수 있었지만, 이것은 그다지 놀라운 일이 아닙니다.  흐름의 중요한 요소의 대부분은 매끄러운 (즉 난류가 아닌) 유입, 유출, 월류 때문입니다.

Because some turbulence was expected to develop in the pool to the left of the overflow, a turbulence model (the Renormalization Group or RNG model) was used in the simulation. Subsequent simulations without a turbulence model produced very similar results, which is not too surprising since most of the important elements of the flow are smooth (i.e., non-turbulent) inflow, overflow and outflow streams.

그림 1b 시뮬레이션 영역은 폭 170cm, 높이 100cm에 가로 80 개, 세로 60 개, 총 4800 개의 셀로 구성되는 같은 크기의 사각형 셀의 격자로 세분화되어 있습니다.  이 격자는 유체 역학의 지배 미분 방정식 (나비에 – 스토크스 방정식)의 유한 차분 근사의 기초로 사용됩니다.  격자 셀의 수와 크기는 흐름 속에서 예측되는 최소의 특성을 파악하는 목적으로 선택되었습니다.  결과를보고 어떤 조정이 필요하다고 생각되는 경우는 숫자를 쉽게 늘리거나 줄일 수 있습니다.  사실, 해상도를 바꾸어 시뮬레이션을 반복하여 계산이 그러한 변화에 영향을 많이 들어 있지 않은지 확인하는 것이 좋습니다.

The simulation region shown in Fig. 1b is 170cm wide and 100cm high and has been subdivided into a grid of equal sized rectangular cells consisting of 80 cells in the horizontal direction and 60 cells in the vertical direction, for a total of 4800 cells. This grid is used as the basis for finite-difference approximations of the governing differential equations of fluid dynamics (the Navier-Stokes equations). The number and size of the grid cells was chosen with the goal of capturing the smallest expected features of the flow. The number can be easily increased or decreased if the results seem to warrant some adjustment. In fact, it is often a good idea to repeat a simulation with a change of resolution to make sure that the solution is not too sensitive to such changes.

왼쪽의 경계는 지정된 속도 경계입니다 (유체의 높이도 지정).  오른쪽의 경계는 유출 경계에서 모든 유량이 경계에 수직 제로 기울기이며, 균일 한 유출이 촉진됩니다.  상하 경계는 단단한 벽으로 세 번째 방향의 경계는 대칭면 (점성 저항 제로의 벽)으로 처리되었습니다.  계단 낙차형상의 표면도 자유-미끄럼(free slip) 경계로 처리되었습니다.

The left boundary was a specified velocity boundary (also with a specified fluid height). The right boundary was an outflow boundary where all flow quantities have a zero gradient normal to the boundary to encourage a uniform outflow. The top and bottom boundaries are rigid walls, while in the third direction the boundaries were treated as planes of symmetry (i.e., walls with zero viscous drag). The surface of the step was also treated as a free-slip boundary.

초기 조건은 예측되는 흐름의 배열을 대략적으로 근사하도록 설정할 수 있었지만, 흐름의 구성은 계산하고 싶은 것 중 하나이기 때문에 유체가 어떻게 분포되는지를 모르는 경우에는 간단한 방법이 필요합니다.  이 예제에서는 비정상 흐름 시뮬레이터를 사용했기 때문에 그림 1a의 계단 낙차형상에 유체의 블록만 있고 왼쪽 경계의 같은 수평 속도와 높이가 할당된 간단한 초기 조건을 정의할 수 있습니다.  시뮬레이션은 이후 정상 흐름으로 발전하고 있지만, 이것은 약 8.0 초 후에 발생합니다.  시뮬레이션은 정상 상태에 도달 한 것을 보장하기 위해, 10.0 초의 시간까지 실행되었습니다.  그림 2는 중간 시간을 두 보여줍니다.  도 2b는 0.2 초, 그림 2c는 0.5 초 시점에서 그림 2d는 마지막 10.0 초 시점을 보여줍니다.

Initial conditions could have been set to roughly approximate the expected flow arrangement, but since the flow configuration is one of the things that one would like to compute, especially for situations where one doesn’t know what the distribution of fluid is likely to be, a simpler approach is needed. Because a transient flow simulator was used for this example a simple initial condition could be defined that consisted of just a block of fluid on top of the step, Fig. 1a with the same horizontal velocity and height assigned to the left boundary. The simulation then followed the development of the steady flow, which occurs after about 8.0s. The simulation was run out to a time of 10.0s to assure that steady conditions had been reached. Figure 2 shows two intermediate times; 2.b at 0.2s and 2.c at 0.5s plus the final time in 2.d at 10.0s.

처음에는 단일 결합하고 있는 자유 표면이었던 것이 액체가 바닥에 충돌한 후 2 개의 독립적인 자유 표면 (상하 스냅 표면)으로 변화하는 것에 주목하십시오.  아래 경계의 충격점의 좌우로 흐름이 분리되도 문제는 없습니다.  이에 대해서는 다음 섹션에서 자세히 설명합니다.

It should be noted that what starts as a single, connected free surface changes to two independent free surfaces (upper and lower nappe surfaces) after the fluid strikes the bottom. No difficulties are experienced with this separation of the flow into portions flowing to the left and right of the impact point on the bottom boundary. This will be discussed at further length in the next section.

실험과 시뮬레이션의 비교는 다음 표와 같으며 매우 잘 일치하고 있습니다.

Comparisons between experiment and simulation are given in the following table and are in excellent agreement.

이러한 결과를 고려하면이 같은 정밀도를 달성하려면 상당한 계산시간이 필요할 것으로 생각될지도 모릅니다.  그러나 실제로는 Pentium 4, 3.20GHz의 데스크톱 컴퓨터의 총 CPU 시간은 단 88 초였습니다. 계산시간이 너무 짧은 것은 설명이 필요하며, 이것은 다음 섹션의 목적입니다.

In view of these results it might be expected that a considerable amount of computational time would be required to achieve such accuracy. In fact, the total cpu time on a desktop Pentium 4, 3.20GHz computer was only 88s. Such a short computational time requires explanation and that is the purpose of the following sections.

Why the VOF Technique Works Well / VOF 법이 적합한 이유

VOF 법의 구조와 그것이 매우 효율적인 방법인 이유를 이해하기 위해 다양한 계산법 중에서도 특히 VOF 법에 대한 몇 가지 기본 개념을 나타냅니다.

There are a few general concepts about computational methods and the VOF technique in particular that can be used to gain an understanding of how and why VOF works so efficiently.

Basic Theory

모든 수치해석 방법에서 흐름의 문제를 단순하게 산술 계산하도록 유한의 수치 세트로 단순화해야합니다.  연속 유체를 이산화된 수치 세트에 근사하기 위해서 일반적으로 사용되는 것이 유체가 차지하는 공간을 격자로 분할하는 방법입니다.  이 격자는 일반적으로 다수의 작은 직사각형의 블록(요소)로 구성됩니다.  이러한 각 요소에 대해 평균화 처리를 실시함으로써 그 요소의 유체의 압력, 밀도, 속도 및 온도의 대표 값을 얻을 수 있습니다.

All numerical methods must use some simplification to reduce a fluid flow problem to a finite set of numerical values that can then be manipulated using elementary arithmetical operations. A typical procedure for approximating a continuous fluid by a discrete set of numerical values is to subdivide the space occupied by the fluid into a grid consisting of a set of small, often rectangular “bricks.” Within each element an averaging process is applied to obtain representative element values for the fluid’s pressure, density, velocity and temperature.

간단한 수식을 사용해, 어느 시간에 걸친 각 요소 값과 인접한 요소의 상호 작용을 근사할 수 있습니다.  예를 들어, 요소의 밀도는 그 요소와 인접 요소 사이에서 (질량 보존에 의한) 질량 유량이 교환된 경우에만 변경됩니다.  요소 사이에서 질량이 교환되는 물질의 속도는 운동량 보존 법칙에 의해 계산되며 일반적으로 나비에-스토크스 방정식으로 표현됩니다.  나비에-스토크스 방정식은 인접한 요소 사이에 작용하는 압력과 점성 응력을 이용하여 요소에서 변화하는 유체 속도를 근사합니다.

Simple equations can be devised to approximate how each element’s values interact with neighboring elements over time. For instance, the density of an element can only change when there is a net flow of mass exchanged between an element and its neighbors (i.e., conservation of mass). The material velocity that carries mass between elements is computed from the conservation of momentum principal, usually expressed in the form of the Navier-Stokes equations, which uses the pressures and viscous stresses acting between neighboring elements to approximate the changing fluid velocities in the elements.

이러한 요소와 인접 요소 사이의 상호 작용에 따른 아이디어는 편미분 방정식 근방의 양의 변화에 의해 생기는 작은 변화의 효과를 평가하는 것과 본질적으로 동일합니다.  공학계의 교과서에서 파생된 작은 컨트롤 볼륨을 사용하여 그 크기를 무한대까지 작게 한 근사치의 극한으로 편미분 방정식이 유도됩니다.  수치 시뮬레이션에서도 같은 방식을 취하고 있지만, 요소 수가 너무 많으면 추적이 어렵게  되어 컨트롤 볼륨의 크기를 최대한 작게 만들 수 없습니다.  실제 시뮬레이션 현상을 해결하는데 충분하고 계산 시간을 최소한으로 억제 할 수 있는 요소수를 설정하는 것이 목표입니다.

This idea of an element interacting with its neighbors is essentially what is meant by a partial differential equation; that is, evaluating the effects of small changes caused by the variation in quantities nearby. Partial differential equations are typically derived in engineering text books as the limit of approximations made with small control volumes whose sizes are then reduced to infinitesimal values. In a numerical simulation the same thing is done except that the control volume sizes cannot be taken to the limit because that would require too many elements to keep track of. In practice, the goal is to use enough elements to resolve the phenomena of interest, and no more, so that computing times are kept to a minimum.

요소에 사용되는 연산은 기본적으로 더하기, 빼기, 곱하기 및 나누기만 포함된 간단한 것입니다.  예를 들어, 요소의 질량의 변화는 일정한 시간 간격에 걸쳐 요소의 측면에서 유입 및 유출된 질량의 가산 및 감산에서 구할 수 있습니다. 그러나 시뮬레이션에서는 이러한 연산을 수천, 때로는 수백만 요소에 대해 매우 짧은 시간 간격에 대해 반복 계산해야합니다.  따라서 이러한 반복 계산의 고속 처리는 컴퓨터가 적합합니다.

Arithmetical operations associated with an element generally involve only simple addition, subtraction, multiplication and division. For instance, the change of mass in an element involves the addition and subtraction of mass entering and leaving through the faces of the element over a fixed interval of time. A simulation requires that these operations be done for thousands or even millions of elements as well as repeated for many small time intervals. Computers are ideal for performing these types of repetitive operations very rapidly.

자유 표면을 수반하는 유체 운동의 시뮬레이션에서는 형상이 변화하는 계산 영역을 다루어야합니다.  이 복잡성에 대응할 수있는 분석 방법이 아래에서 설명하는 VOF 법입니다.

Simulating fluid motion with free surfaces introduces the complexity of having to deal with solution regions whose shapes are changing. A convenient way to deal with this is to use the Volume of Fluid (VOF) technique described next.

The VOF Concept

VOF 법은 각 격자 셀의 체적 중 액체가 차지하는 비율, 즉 체적 점유율을 기록한다는 생각에 근거합니다.  일반적으로 부피 점유율은  F로 표시됩니다.  F는 부피 점유율이기 때문에 값이 취할 수있는 범위는 0.0 ~ 1.0입니다.

The VOF technique is based on the idea of recording in each grid cell the fractional portion of the cell volume that is occupied by liquid. Typically the fractional volume is represented by the quantity F. Because it is a fractional volume, F must have a value between 0.0 and 1.0.

액체 내부의 영역에서는 F 값은 1.0이 액체의 외부, 즉 (공기 등) 기체 영역에서 F 값은 0입니다.  F 값이 0.0과 1.0 사이에서 변화하는 장소가 자유 표면이 존재하는 위치입니다.  즉 0.0보다 크고 1.0보다 작은 F 값을 가지는 요소는 반드시 표면을 가지고 있습니다.

In interior regions of liquid the value of F would be 1.0, while outside of the liquid, in regions of gas (air for example), the value of F is zero. The location of a free surface is where F changes from 0.0 to 1.0. Thus, any element having an F value lying between 0.0 and 1.0 must contain a surface.

여기서 유의해야 할 것은 VOF 법에서 자유 표면을 직접적으로 정의하는 것이 아니라 벌크 유체의 위치를 정의한다는 점입니다.  이렇게하면 계산상의 어려움을 초래하지 않고 유체 영역을 결합 또는 분할 할 수 있습니다.  자유 표면은 단순히 유체의 체적 점유율이 1.0과 0.0 사이에서 변화하는 장소로 정의됩니다.  이것은 자유 표면을 수반하는 거의 모든 문제에 적용 할 수 VOF 법의 뛰어난 특징이기도합니다.

It is important to emphasize that the VOF technique does not directly define a free surface, but rather defines the location of bulk fluid. It is for this reason that fluid regions can coalesce or break up without causing computational difficulties. Free surfaces are simply a consequence of where the fluid volume fraction passes from 1.0 to 0.0. This is a very desirable feature that makes the VOF technique applicable to just about any kind of free surface problem.

또한 격자의 각 요소에 단일 수치 (F)를 할당하여 유체의 위치를 기록 할 수 있는 점도 VOF 법의 중요한 특징입니다.  이것은 평균값을 기준으로 압력과 속도 등 다른 모든 유체 물성의 기록과 완전히 일치합니다.

Another important feature of the VOF technique is that it records the location of fluid by assigning a single numerical value (F) to each grid element. This is completely consistent with the recording of all other fluid properties in an element such as pressure and velocity components by their average values.

Some Details of the VOF Technique

Figure 3. Surface in 1D column of elements.

정확도를 위해 요소 내에 자유 표면을 배치하는 방법을 갖는 것이 바람직합니다. 인접 요소의 F 값을 고려하면 이를 쉽게 할 수 있습니다.  예를 들어, 열의 일부에 액체가 충전되어있는 1 차원 요소를 상상하십시오 (그림 3).  액체의 표면은 열 중앙 영역의 요소에 있습니다.  이것을 표면 요소라고합니다.  여기에서는 표면 요소를 제외하고 F 값은 0.0 또는 1.0이어야한다고 가정하고 있기 때문에 이를 사용하여 표면의 정확한 위치를 파악할 수 있습니다.  우선, 표면이 표면 또는 바닥을 확인하는 테스트를 실시합니다.  표면요소에 대해 액체가 없을 경우에는 표면으로 간주합니다.  위의 요소에 액체가 들어있는 경우는 물론, 그 표면은 바닥입니다.  윗면에 관해서는 정확한 위치는 표면 요소의 아래쪽에서 위쪽으로 요소의 세로 크기를 F 배 한 거리에있는로 계산합니다.  바닥도 마찬가지로 표면 요소의 상단에서 아래로, 요소의 세로 크기를 F 배 한 거리에 있습니다.  이 방법에 의한 요소의 표면 위치의 특정은 요소 내의 액체의 부피 점유율로 F를 정의한 후에 합니다.

For accuracy purposes it is desirable to have a way to locate a free surface within an element. Considering the F values in neighboring elements can easily do this. For example, imagine a one-dimensional column of elements in which a portion of the column is filled with liquid, Fig. 3. The liquid surface is in an element in the central region of the column, which will be referred to as the surface element. Because we assume the values of F must be either 0.0 or 1.0, except in the surface element, we can use this to locate the exact position of the surface. First a test is made to see if the surface is a top or bottom surface. If the element above the surface element is empty of liquid, the surface must be a top surface. It the element above is full of liquid then, of course, the surface is a bottom surface. For a top surface we compute its exact location as lying above the bottom edge of the surface element by a distance equal to F times the vertical size of the element. A bottom surface is similarly located a distance equal to F times the vertical size of the element below the top edge of the surface element. Locating the surface within an element in this way follows from the definition of F as a fractional volume of liquid in the element.

1 차원 열의 표면 위치 계산은 간단하고 정확하며 계산이 거의 필요없습니다. 그러나 2 차원 및 3 차원의 경우 하나의 표면 셀에 연속적인 표면 방향이 존재할 가능성이 있기 때문에 위치 계산은 조금 복잡해집니다.  그럼에도 불구하고 이를 취급하는 것은 어렵지 않습니다.  그림 4의 이차원의 예는 표면의 위치를 계산할 뿐만 아니라 경사와 곡률도 이해할 수 있는 쉬운 방법을 보여줍니다.

Calculating surface locations in one-dimensional columns is simple, accurate and requires very little arithmetic. In two and three dimensional situations, however, computing a location is a little more complicated because there is a continuous range of surface orientations possible within a surface cell. Nevertheless, dealing with this is not difficult. A two-dimensional example, Fig. 4, will illustrate a simple way to not only compute the location of the surface, but also to get a good idea of its slope and curvature.

Figure 4. Surface in 2D grid of elements.

1 차원의 경우처럼 먼저 인근 요소를 테스트하여 표면의 대략적인 방향을 찾아야합니다.  그림 4는 바깥 쪽의 법선이 상승 방향에 가장 가깝게 됩니다.  이것은 그 방향 밖의 값의 차이가 다른 방향보다 크기 때문입니다.  그럼 거의 수직으로 있는 요소 열에서 표면의 국소적인 높이가 계산됩니다.  그림 4의 2 차원의 경우에는 이러한 높이가 화살표로 표시되어 있습니다.  마지막으로, 표면 요소를 포함하는 컬럼의 높이에 따라 그 요소의 표면의 위치를 확인합니다.  다른 2 개의 높이를 사용하면 국소적인 표면 경사와 표면 곡률을 계산할 수 있습니다.

As in the one-dimensional case, it is first necessary to find the approximate orientation of the surface by testing the neighboring elements. In Fig. 4 the outward normal would be closest to the upward direction because the difference in neighboring values in that direction is larger than in any other direction. Next, local heights of the surface are computed in element columns that lie in the approximate normal direction. For the two-dimensional case in Fig. 4 these heights are indicated by arrows. Finally, the height in the column containing the surface element gives the location of the surface in that element, while the other two heights can be used to compute the local surface slope and surface curvature.

3 차원에서도 동일한 절차를 사용하지만, 표면 요소의 주위에 있는 9개의 열에 대해 열 높이를 요구해야합니다.  필요한 계산은 조금 더 걸리지만, 주된 내용은 열의 간단한 덧셈과 경사와 곡률을 추구하는 열의 높이의 합과 차이가 있습니다.  이 토론을 토대로, 이제 자유 표면을 정의하는 데 필요한 모든 정보를 빠르고 쉽게 평가하기 위해 부분 유체 체적을 사용하는 방법을 알아야합니다.

In three-dimensions the same procedure is used although column heights must be evaluated for nine columns around the surface element. Although a little more computation is needed, it consists primarily of simple summations in the columns and then sums and differences of column heights for evaluating the slope and curvature. Based on this discussion, the reader should now see how the fractional fluid volume can be used to quickly and easily evaluate all the information needed to define free surfaces.

다루어야 할 문제가 앞으로 2 개 남아 있습니다.  하나는 그림 1 및 2와 같은 시뮬레이션은 유체가 존재하는 영역에는 유체 역학만으로 해결합니다.  이것은 VOF 법의 계산 효율이 높은 또 하나의 이유입니다.  계단 형상의 낙하류의 문제로 유체가 차지하는 영역은 계산 격자의 오픈 공간의 절반 이하입니다.  액체를 둘러싼 기체의 흐름을 계산할 필요가 있다면 필요한 계산 시간이 크게 늘어납니다.  그러나 액체만으로 계산을 할 경우 자유 표면 경계 조건을 지정해야합니다.  이 조건은 접선 응력의 소실과 기체의 압력에 동일한 표준 압력을 표면에 추가하는 것입니다.

There are two remaining issues to deal with. One issue is that a simulation like that in Figs. 1 and 2 is only solving for the fluid dynamics in regions where there is fluid. This is another reason for the computational efficiency of the VOF method. The region occupied by fluid in the flow over a step problem is much less than half of the open region in the computational grid. If it were necessary to also solve for the flow of gas surrounding the liquid, then considerably more computational time would be required. In order to perform solutions only in the liquid, however, it is necessary to specify boundary conditions at free surfaces. These conditions are the vanishing of the tangential stress and application of a normal pressure at the surface that equals the pressure of the gas.

두 번째 문제는 자유 표면이 유체와 함께 움직일 때의 움직임과 변형을 유체 점유율 변수 F를 구함으로써 계산해야 한다는 것입니다.  변수 F는 불연속 (주로 0.0 또는 1.0)이기 때문에 계산 격자를 이동할 때 이 불연속성이 유지되도록주의해야합니다.  VOF 법은이 목적으로 특수 이류(advection) 알고리즘이 사용되고 있습니다.

A second issue is that movement and deformation of a free surface must be computed by solving for the fraction of fluid variable, F, as it moves with the fluid. Because the variable F is discontinuous (i.e., primarily 0.0 or 1.0) some care must be taken to maintain this discontinuity as it moves through a computational grid. In the VOF method, special advection algorithms are used for this purpose.

Illustration of Free-Surface Tracking by VOF Technique

그림 6a는 이것의 적합 여부를 보여줍니다.  유체의 체적 점유율은 격자 요소마다 균일하게 분류되고 그 요소의 값을 나타냅니다.  자유 표면은 거의 모든 곳에서 선명하게 정의되어 있습니다.  스냅의 가장 낮은 가장 좁은 부분에만 선명한 유체 분포의 손실을 확인할 수 있습니다 (그림 5b).  이것은 예상대로입니다.  이 영역에서는 스냅의 두께는 3 가지 요소보다 작고, 따라서 부분 충전된 표면 요소에 연결된 작은 F 값이 어떤 중심 요소 (값 1.0)에 혼입하기 때문입니다.  계산 목적으로 이 것은 별로 문제가 되지 않습니다.  이 시뮬레이션 방법은 액체 내부의 요소는 순수한 액체 성분과 같은 방식으로 처리되기 때문입니다.

Figure 6a is an illustration of how well this works; the fluid volume fraction is colored uniformly in each grid element to represent its value in that element. The free surface is sharply defined nearly everywhere. Only in the lowest and narrowest part of the nappe is there any noticeable loss of a sharp fluid fraction distribution, Fig. 5b. This was expected because in this region the nappe is less than three elements in thickness and this allows some of the smaller F values associated with partially filled surface elements to mix in with the central element, which should have a value of 1.0. For computational purposes this doesn’t really matter because the simulation method treats elements interior to the liquid as though they are pure liquid elements.

그림 5b에 나타내는 영역에서는 실제 실험에서 난류 및 공기 혼입이 관찰된 것도 지적해 두지 않으면 안됩니다.  따라서 유체 점유율의 값을 1보다 조금 작게 보이는 것이 다소 현실적입니다.  이것은 전혀 의외라는 것은 없습니다.  난류와 공기 유입을 담당하는 풀의 액체 제트의 교점은 난류와 공기 유입의 원인이 되지만, 유체 점유율 값(fluid fraction values )은 액체 내부에 “유입” 원인이 되기 때문에 실수가 아닙니다.

It should also be pointed out that in the region shown in Fig. 5b turbulence and air entrainment are observed in actual experiments. Thus, the appearance of fluid fraction values a little less than unity is somewhat realistic. This is not entirely accidental because the intersection of jet of liquid with a pool, which is responsible for turbulence and air entrainment, is also responsible for the “entrainment” of fluid fraction values into the interior of the liquid.

Summary

처음에는 컴퓨터가 단순히 반복적인 산술 연산을 수행하고, 복잡하고 시간에 의존적인 유체 역학 문제에 대해, 현실적인 시뮬레이션을 할 수 있다는 것이 다소 마술처럼 보일 수 있습니다. 이 논의의 목적은 비교적 기본적인 절차로 이를 수행하는 접근법을 설명하는 것입니다.

간단하지만 사소한 유압 흐름 예제를 사용하여 계산된 시뮬레이션이 물리적인 측정 결과와 매우 일치하는 세부 결과를 생성 할 수 있음이 입증되었습니다. VOF (Volume of Fluid) 기술을 기반으로 한 시뮬레이션은 정확하고, 매우 효율적인 것이 추가로 입증되었습니다.

분명하게, 수력 발전소에서 사용되는 것과 같은 복잡한 유압 구조와 관련된 실제 예는 유용한 결과를 얻기 위해서는 이 예에서 사용되는 몇 초 이상의 많은 계산 시간을 소비해야합니다. 그럼에도 불구하고 이러한 결과는 합리적인 시간 (사람과 컴퓨터 모두)에서 수행 될 수 있으며, 실제 실험에서는 거의 불가능한 세부 사항들을 포함합니다. 또한, 지오메트리, 유동 조건 또는 유체 특성의 거의 모든 종류의 변화의 영향을 쉽게 테스트 할 수있는 능력은 시뮬레이션을 사용하는 또 다른 강력한 이유입니다. 기술의 발전에 따라 hydraulic flow 시뮬레이션을 위한 현재 소프트웨어 및 하드웨어는 기존의 물리적 모델링에 비해 상당한 비용 이점을 제공합니다.

At first it may seem somewhat magical that a computer can simply perform repeated arithmetic operations on arrays of numbers and produce a realistic simulation of a complex, time-dependent, fluid dynamics problem. It was the purpose of this discussion to explain an approach that does this with relatively elementary procedures.

Using a simple, but non-trivial, hydraulic flow example it has been demonstrated that computational simulations can produce detailed results in excellent agreement with physical measurements. It has been further demonstrated that the simulation, which was based on the Volume of Fluid (VOF) technique, uses simple approximation methods that are both accurate and efficient.

Clearly, real world examples involving complex hydraulic structures such as those used in hydroelectric power stations, must consume more than the few seconds of computational time used in our example to obtain useful results. Nevertheless, those results can be generated in reasonable times (both man and computer) and contain a richness of detail rarely possible in physical experiments. For examples visit our water and environmental application pages. In addition, the ability to easily test the influence of just about any kind of change in geometry, flow condition or fluid property is another powerful reason to employ simulations. Current software and hardware for hydraulic flow simulations offer a significant cost advantage over traditional physical modeling.
