摘要

提出了复杂形态血管血流的力学模型。在ABAQUS软件中对四种血管病变进行了有限元模拟。推导了非牛顿流体的控制方程，建立了流固耦合的半滑移边界条件。通过计算机模拟得到了病变血管的流速和压力分布。

Computer simulation of blood flow in certain types of the blood vessels pathologies

The mechanical models of the blood flow in the vessels with complicated forms are proposed. Four kinds of vessel pathologies are considered and simulated by means of FEM in the ABAQUS software application. The governing equations for Non-Newtonian liquid were derived and the semi-slip boundary condition was formulated for fluid-structure interaction. As a result of computer simulation the velocity and pressure distributions were obtained for pathological regions of vessels.
