摘要
文研究了脉动血流通过局部缓慢狭窄幅度径向振荡的弹性直圆管时压强和压强梯度的分布特征。分析表明在局部狭窄幅度径向振荡的弹性管中压强及压强梯度分布与在直圆管或局部狭窄静止的情况下明显不同、而且它与Ｗｏｒｍｅｒｓｌｅｙ数、管壁特征、及狭窄幅度振荡频率有密切关系。此项研究对进一步认识分析某些病理和治疗手法等有重要意义。
In this study, a pulsatile flow of a viscous incompressible fluid through an elastic straight tube witha mild stenosis whose amplitude oscillates in its radial direction was investigated. The distributionof pressure and pressure gradient was obviously different from those of flow through a straight tubewith an static stenosis. And it is closdy connected with Wormersley parameter, character of thewall of the tube, and the frequency of the stenosis amplitude oscillation. This study is important forfurther analysis of certain pathology or curative method.
