A Hybrid FEM Algorithm for Fluid Flow in a Visco-Elastic Pipe

摘要: 本文提出了一个求解粘弹性管内流体流动的变分原理.采用特征函数展开式与有限单元法相结合的杂交方法,求解内区的速度场及外区波的反射、透射系数.作为一个算例,计算了轴对称血栓对简谐振荡流动的影响.

Abstract: A variational principle of hybrid FEM is proposed to solve the flow in a visco-elaslic pipe. As an example, the influence of an axisymmetrical stenosis on an artery vibrating flow with a single frequency is calculated.
