研究了通过狭窄动脉几何形状的稀固液悬浮液的颗粒分布。采用粒子图像测速技术（PIV）测量流场速度并获取流场图像。评价由颗粒散射的光强度以确定颗粒分布。在流动从狭窄喉部出现的地方存在流动分离。从PIV图像，颗粒密度分布表现出不同的不均匀特性，随流速，颗粒尺寸和颗粒浓度。在低流速下，形成无颗粒层。随着流速的增加，颗粒在下游涡流内的同心再循环轨道中积聚。具有较大尺寸和较高浓度的颗粒倾向于向涡旋中心聚集更多。
The particle distribution of a dilute solid-liquid suspension through a stenosed arterial geometry was investigated. Particle image velocimetry (PIV) was used to determine the velocity as well as to acquire the flow images. The light intensity scattered by particles was evaluated to determine the particle distribution. Flow separation exists where the flow emerges from the stenosis throat. From the PIV images, the particle density distribution exhibited differing non-uniform characteristics which vary with flow rate, particle size and particle concentration. At low flow rates, a particle-free layer is formed. As the flow rate is increased, particles accumulate in concentric recirculation orbits within the downstream vortex. Particles with larger size and higher concentration tend to accumulate more towards the center of the vortex.
