| 摘 要： | 本文研究缓变狭窄幅度径向振荡血管内血液脉动流。求解线化的Ｎａｖｉｅｒ－Ｓｔ－ｏｋｅｓ血流方程和管壁方程，得出速度剖面和管壁切庆力。结果表明狭窄参数的变化对流动有很大影响。在狭窄区仙，速度变化和狭窄程度及狭窄幅度振荡频率的耦合作用有关。当狭窄幅度振荡频率接近血流基频时，血液速度变化较大，并且狭窄区最大壁切应力达到峰值。

| Abstract: | In this paper, pulsative flow through a vessel with mild stenosis amplitude oscillating radically wasinvestigated. Velocities and wall shear stress were obtained by solving linearlzed N-S equations andWall equation. Results showed stenosis parameters had effect on blood flow. Variations in velocitywas sever and maximum wall shear stress reached peak value at stenosis amplitude oscillatingfrequency near the flow basic frequency. |
