Abstract
Pulsatile flow across two circular cylinders with different geometric arrangements is studied experimentally using the particle image velocimetry method and numerically using the finite element method. This investigation is motivated the need to optimize gas transfer and fluid mechanical impedance for a total artificial lung, in which the right heart pumps blood across a bundle of hollow microfibers. Vortex formation was found to occur at lower Reynolds numbers in pulsatile flow than in steady flow, and the vortex structure depends strongly on the geometric arrangement of the cylinders and on the Reynolds and Stokes numbers.
摘要
利用粒子图像测速法对通过两种具有不同几何排列的圆柱体的脉动流进行了实验研究，并使用有限元法进行了数值研究。这项研究的动机是需要优化全人工肺的气体传输和流体机械阻抗，在全人工肺中，右心将血液泵过一束中空微纤维。研究发现，脉动流中涡旋的形成发生在比稳定流更低的雷诺数下，并且涡旋结构强烈依赖于圆柱体的几何排列以及雷诺数和斯托克斯数。
