Blood flow in an artery with two successive bends is simulated by a finite-element computation of steady flow of a Newtonian viscous fluid through a rigid tube having the same shape as a specific part of the femoral artery. Notwithstanding the fact that the bends in the model geometry are rather gentle, the axial and secondary flow patterns, computed for a range of values of the Reynolds number Re, show strong and complicated three-dimensional flow effects. In particular, the flow pattern in the second bend for relatively small values of Re (Re < 240) turns out to be drastically different from that for larger Re-values.
通过对牛顿粘性流体在与股动脉特定部分形状相同的刚性管中进行稳定流动的有限元计算，模拟了具有两个连续弯曲的动脉中的血流情况。尽管模型几何形状中的弯曲相当平缓，但针对一系列雷诺数Re计算得到的轴向和二次流模式显示出强烈且复杂的三维流动效应。特别是，对于相对较小的Re值（Re < 240），第二个弯曲处的流动模式与较大Re值时的流动模式截然不同。
