The fluid mechanics of dynamically constricted tubes in pulsatile flow. This project is aimed at advancing the fundamental understanding of flow instability, the transition to turbulence and the effect on wall shear stress, in a dynamically constricted tube flow. The project will provide the first accurately resolved experimental flow analysis, using tomographic particle imaging velocimetry and 3D laser doppler anemometry, conducted on a novel experimental model, and will resolve, for the first time, turbulence characteristics of the dynamic constriction, using direct numerical simulation with a novel moving boundary implementation. The outcomes will provide the key link between fluid mechanics and wall shear stress, allowing future progress to be made in elucidating the causes of cardiovascular disease.\n

脉动流中动态收缩管的流体力学。该项目的目的是推进流动不稳定性的基本理解，过渡到湍流和壁面剪应力的影响，在动态收缩管流。该项目将提供第一个精确解决的实验流分析，使用断层粒子成像测速和三维激光多普勒测速，进行了一个新的实验模型，并将解决，第一次，湍流特性的动态收缩，使用直接数值模拟与一个新的移动边界实现。这些结果将提供流体力学和壁面切应力之间的关键联系，使未来在阐明心血管疾病的原因方面取得进展。n
