摘要

研究了在母动脉存在单一轻度狭窄的情况下,血液流经狭窄分叉动脉的行为的数值模拟。流动分析将不可压缩、稳定的三维Navier-Stokes方程应用于非牛顿广义幂律流体。采用基于有限元法的COMSOL Multiphysics对血流行为进行了数值模拟。结果显示了狭窄严重程度对流动特性(如轴向速度)的影响,并显示了用于分析流线模式的流动再循环区。

3D Model of Generalized Power Law Blood Flow in a Stenosed Bifurcated Artery
Numerical simulation of the behaviour of blood flow through a stenosed bifurcated artery with the presence of single mild stenosis at parent artery is investigated. The flow analysis applies the incompressible, steady, three-dimensional Navier-Stokes equations for non-Newtonian generalized power law fluids. Behaviour of blood flow is simulated numerically using COMSOL Multiphysics that based on finite element method. The results show the effect of severity of stenosis on flow characteristics such as axial velocity and its exhibit flow recirculation zone for analysis on streamlines pattern.
