Capillary Flows

모세관 흐름은 일반적으로 미세 유체 장치에서 발생합니다. 예를 들어, 바이오 칩 설계에서는 한 곳에서 다른 곳으로 액체 용액을 전달하기 위해 긴 마이크로 채널이 자주 사용됩니다. 입구 채널은 액체 저장소에 연결되고 표면 장력은 액체를 마이크로 채널로 끌어 당깁니다 (액체가 칩 표면에 “젖은”경우). 이 페이지에서는 충진, 흡수 및 전환과 같은 모세관 흐름 분석에서 FLOW-3D의 특정 응용 분야를 다룹니다.

Marangoni flow는 중앙에서 데워진 물이 담긴 접시에 흐릅니다. 불균일한 표면 장력에 의해 생성 된 흐름은 20ºC의 초기 온도에서 0.75cm 깊이의 얕은 8.0cm 직경의 물 접시에 의해 입증됩니다. 원형 접시의 중앙에는 직경 0.5cm의 원통형 막대가 있습니다. 80 Cº의 온도로 가열하고 0.05 cm 깊이까지 수면에 담근다. 핫로드 근처의 물이 가열됨에 따라 표면 장력이 0.1678 dyne / cm / ºC만큼 감소하여 표면이 접시의 바깥 쪽 테두리쪽으로 후퇴합니다. Retraction는 처음에 표면에 뿌려진 질량없는 마커 입자로 표시됩니다.

Capillary Absorption

고체 물질의 기공에 모세관 흡수 때문에 액체와 고체 사이의 접착 발생합니다. 이 같은 흡수의 간단하면서도 유용한 시험은 핀란드 ABO Akademi 대학의 마르티 Toivakka에 의해 제안되었습니다. 테스트 기공은 ± 1.0 μm의 측면 벽 1.0 μm의 반경 원호입니다. 팽창 목에 연결된 넓은 2차원 채널로 구성되어 있습니다. 체적력의 부재 하에서, 표면장력 과 wall adhesion pull liquid 는 액체와 고체 사이의 static contact angle에 의해 결정됩니다. 첨부된 그림은 FLOW-3D가 올바르게 특정 접촉 각도 (유체는 적색표현) 충전 레벨을 계산하는 것을 나타냅니다.

Thermocapillary Switch

액체의 작은 덩어리나 가벼운 빔의 경로에서 움직이는 굴절, 혹은 반사로 다른 길로 리디렉션 할 수 있습니다. 이 개념은 특히나 한번 빔 내부 반사로 인해 갇혀 있는 섬유에 들어가 광학 섬유로 연결에서 매력적입니다. 어떠한 복잡성의 광 회로를 만들려면, 하나의 광섬유에서 다른 가벼운 방향을 바꿀 수 있는“스위치”를 둘 필요가 있습니다.

Capillary Filling

모세관 충전 과정을 이해하는 것은 칩 설계에 중요합니다.. 액체 흐름 통로의 다른 형상 포획 기포의 가능성 등의 충전 공정의 기술은, 같은 챔버와 칩의 내부 구조를 배치 기둥 분할하고, 밸브 결합에 설계자 안내 등 다양한 모세관 충전 동작이 발생할 수 있습니다.

시뮬레이션은 아래의 모세관 작용의 분석 예측의 유효성을 검사합니다. 모세관 채우기는 정확하게 표면 장력과 중력에 의해 균형을 잡습니다.이것은 FLOW-3D에 의해서 정확하게 예측되는 기본적인 과정입니다.

Thermocapillary Actuation

Thermocapillary Actuation

표면 장력의 온도 의존성은 유체 방울을 패턴 있는 표면 위로 전달하는 데 사용될 수 있습니다. 표면은 유체 방울이 친수성-수소성 인터페이스에 의해 형성된 채널을 따르도록 제한되도록 친수성 또는 친수성 접촉 각도로 패턴화됩니다. 또한 프로그램 가능한 방식으로 가열된 마이크로 히터의 배열은 열전압 작동을 유발하여 유체 방울을 뜨거운 영역에서 차가운 지역으로 유도합니다. 아래 이미지는 문제 설정의 상단 및 단면 뷰(Anton A)를 보여줍니다. Darhuber 외.) 다음에 Flow-3D를 설정합니다.

The array of Ti-resistors (shown in light gray) beneath the hydrophilic stripes locally heat the droplet thereby modifying the surface tension and propelling the liquid toward the colder regions of the device surface. The dark gray stripes represent the leads and contacts (Au) for the heating resistors.

더 차가운 표면 온도 영역은 인접한 따뜻한 지점보다 더 높은 표면 장력을 유지하여 액체를 당기는 접선 표면 힘을가합니다. 부분적 습윤 (접촉각> 0) 표면은 전체 습윤 표면 (접촉각 = 0)에 비해 부피 손실이 적은 유체 수송을 허용하기 때문에 바람직한 옵션입니다.

아래 애니메이션은 완전히 젖은 표면과 부분적으로 젖은 표면의 비교를 보여줍니다. 예상대로 완전히 젖은 표면은 부분적으로 젖은 표면보다 액적을 더 평평하게 (그리고 더 많이 퍼지게) 만듭니다. 히터가 한 번에 하나씩 활성화되면 물방울이 더 차가운 영역으로 이동됩니다. 더 많은 유체가 남겨질수록 시뮬레이션이 끝날 때까지 완전히 젖은 표면은 더 많은 유체 볼륨을 잃는 것을 볼 수 있습니다. 따라서 부분적으로 젖은 표면은 유체 손실을 줄이기위한 더 바람직한 옵션입니다. 두 경우 모두 소수성 표면으로 둘러싸인 중앙 친수성 스트립으로 인해 물방울이 중앙에 머물러야합니다.

Digital Microfluidics

Electrowetting은 전기장을 사용하여 표면 습윤 특성을 변경하는 과정입니다. Digital microfluidics는 전기 습식이 개별 유체 방울을 제어하고 조작하는데 사용되는 미세 유체 분야입니다. 이 아이디어는 디지털 마이크로 일렉트로닉스에서 영감을 얻었지만 전류 대신 이산 (또는 디지털화 된)액적을 사용하여 특정 시간 내에 특정 거리에 포함된 특정 양의 유체 또는 반응물을 이동합니다. 디지털 마이크로 플루이딕스는 높은 재구성 가능성과 대규모 병렬화를 통해 프로세스 속도를 높일 수있는 능력 때문에 다양한 바이오칩 설계에서 응용 분야를 찾습니다.

가장 중요한 표면 습윤 특성은 유체와 표면 사이의 접촉각입니다. FLOW-3D의 강력한 표면장력 모델은 전기 운동 모델과 함께 유전 영동, 열 모세관 작동 (온도에 따른 표면 장력을 통한 작동) 및 전기 습윤 자체와 같은 디지털 미세 유체 공정에서 습윤 역학을 포착하는 데 사용됩니다.

모세관 흐름은 일반적으로 미세 유체 장치에서 발생합니다. 예를 들어, 바이오 칩 설계에서 긴 마이크로 채널은 종종 액체 용액을 한 장소에서 다른 장소로 전달하는 데 사용됩니다. 입구 채널은 액체 저장소에 연결되고 표면 장력이 액체를 마이크로 채널로 당깁니다(액체가 칩 표면에 “습기”되는 경우). 이 페이지에서는 충전, 흡수 및 전환과 같은 모세관 흐름 분석에서 FLOW-3D에 대한 몇 가지 특정 용도에 대해 다룹니다.

Marangoni Flows

마랑고니는 그 중심에 가열된 물 접시에 흐릅니다. 균일하지 않은 표면 장력에 의해 발생하는 흐름은 20ºC의 초기 온도에서 깊이 0.75cm의 얕은 8.0cm의 물 접시에 의해 입증됩니다. 원형 접시 중앙에 놓인 원통형 막대는 직경 0.5cm로 80Cº의 온도로 가열되고 0.05cm의 깊이까지 수면에 잠깁니다. 핫 로드 주변의 물이 가열되면 표면 장력이 0.1678dyne/cm/ºC만큼 감소하여 표면이 접시의 바깥쪽 림 쪽으로 수축됩니다. 수축은 처음에 표면에 뿌려진 질량이 없는 마커 입자에 의해 나타납니다.

Capillary Filling

모세관 충전 공정을 이해하는 것은 칩 설계에 중요합니다. 액체 흐름 경로의 기하학적 구조가 다르면 기포를 고정할 수 있는 등의 모세관 충진 동작이 달라질 수 있습니다. 충전 프로세스에 대한 지식은 설계자가 챔버, 결합 기둥, 분할 및 밸브와 같은 칩의 내부 구조를 정렬하는 데 도움이 됩니다. 오른쪽의 시뮬레이션은 모세관 작용의 분석적 예측을 검증합니다. 모세관 충전은 표면 장력과 중력에 의해 균형을 이루며, 이는 FLOW-3D로 정확하게 예측되는 기본 공정입니다.

Thermocapillary Switch

910/5000광선의 경로 안팎으로 이동하는 소량의 액체는 굴절이나 반사를 통해 다른 경로로 방향을 바꿀 수 있습니다. 이 개념은 광선이 광섬유에 들어가면 내부 반사에 의해 포착되는 광섬유와 관련하여 특히 매력적입니다. 복잡한 광학 회로를 만들려면 한 광섬유에서 다른 광섬유로 빛을 리디렉션 할 수있는 “스위치”가 필요합니다.

제안 된 한 가지 개념은 열 모세관을 기반으로합니다. 광섬유 광선을 교차하는 마이크로 채널에 액체의 작은 방울을 놓습니다. 방울이 채널을 따라 빔이 통과해야하는 곳으로 이동하면 빔이 다른 섬유로 반사됩니다. 방울은 양면을 다르게 가열하여 이동합니다. 이것은 방울이 채널의 더 차가운 끝쪽으로 당겨 지도록 방울의 양쪽에있는 반월판의 표면 장력의 변화를 일으 킵니다.

모세관 기반 마이크로 시스템은 추가 작동 메커니즘이 필요하지 않기 때문에 저렴하고 제작하기 쉽습니다. 마이크로펌프나 주사기와 같은 일반적인 마이크로 시스템은 부피가 크고 휴대할 수 없는 흐름 작동을 필요로 합니다.

버팔로 대학의 최근 연구는 모세관 유동 작용을 사용하여 미세 기기에서 액체를 이동시키는 간단한 해결책을 연구했습니다. 이 작업은 FLOW-3D를 사용하여 수정된 V-그루브 채널에서 자발적 모세관 흐름을 시뮬레이션합니다. 좁은 V-그루브 기하학(왼쪽)은 전혈과 같은 높은 점도의 유체도 이 유체를 통해 이동할 수 있기 때문에 좋은 솔루션을 제공합니다. 홈의 끝부분은 자발적인 모세관 흐름을 촉진하고 평행판은 충분한 혈액수송을 보장합니다.

본 연구에서는 FLOW-3D를 사용하여 채널 내 유체 헤드의 유속과 액체 전방의 진행을 추정합니다.

결과는 실험 및 분석(간단한) 결과와 비교됩니다. 아래 그림은 수치, 실험 및 분석 결과의 비교를 보여줍니다. FLOW-3D 결과는 실험 결과와 매우 일치합니다.

A Surface Tension Model Update [표면장력 모델 업데이트]

PURPOSE AND BACKGROUND
The modeling of surface tension forces is computationally difficult because it requires the evaluation of surface curvatures, i.e., second derivatives of the surface location. This is
particularly true in FLOW-3D® since it uses a regular rectangular grid that does not conform to surface shapes. Although this simple grid structure makes it more difficult to evaluate surface
slopes and curvatures, it is this feature that also gives the strength needed to simulate coalescence and breakup of fluid blobs.
Evaluation of surface slope and curvature in FLOW-3D® is done by determining which coordinate direction is closest to the outward normal vector to the surface. Then fluid in a 3 by 3
by 3 set of grid cells surrounding a given cell is summed up in the cell columns parallel to the normal. This, in effect, gives a discrete representation of the surface height in nine (3×3)
columns, which can be used to compute slopes and curvatures.
In most cases this procedure works quite well, but when normal directions in the grid are near 45° the surface may be too steep for this procedure to work accurately. A consequence of this
loss of accuracy is the introduction of spurious pressures or perturbations that sometimes generate undesirable capillary waves (i.e., kinetic energy noise). Occasionally, these
perturbations can even destroy a computation.
A summary of the original surface tension model was given in Technical Note TN6, “Surface Tension Validation Tests,” (1987). Since that Note there have been a number of major improvements:

1. Wall adhesion sensitive to slope of wall,
2. Static contact angle as an obstacle property,
3. Two-fluid interfacial surface tension,
4. Thermocapillary (i.e., tangential) surface forces (see TN47).

In this Technical Note we document another improvement that has been made. In particular, we have improved the accuracy of the column summation technique for the computation of surface
curvatures. As the following examples will show, this improvement is quite dramatic in many cases where the earlier model experienced substantial difficulties.
