The evidence for hypothesizing a relationship between hemodynamics and atherogenesis as well as the motivation for selecting the carotid bifurcation for extensive fluid dynamic studies has been discussed in Part I of this two-paper sequence. Part II deals with velocity measurements within the bifurcation model described by Fig. 1 and Table 1 of the previous paper. A plexiglass model conforming to the dimensions of the average carotid bifurcation was machined and employed for velocity measurements with a laser-Doppler anemometer (LDA). The objective of this phase of the study was to obtain quantitative information on the velocity field and to estimate levels and directions of wall shear stress in the region of the bifurcation.
在这两篇论文系列的第一部分中,已经讨论了关于血流动力学与动脉粥样硬化形成之间关系的假设证据,以及选择颈动脉分叉处进行广泛流体动力学研究的动机。第二部分涉及对上一篇论文中图1和表1所描述的分叉模型内的速度测量。加工了一个符合平均颈动脉分叉尺寸的有机玻璃模型,并使用激光多普勒风速仪(LDA)进行速度测量。本研究阶段的目的是获得关于速度场的定量信息,并估计分叉区域壁面剪应力的水平和方向。
