摘要

本文采用可计算粘性亚层数值的双方程湍流有限元模型对血流进行了模拟分析。对方程进行隐式积分,确定流体速度、流体压力、湍流、动能和湍流动能耗散。这些值是在增量迭代法每一步的有限元节点中计算出来的。建立了紊流有限元模型,定制生成有限元网格,用于复杂血流问题的计算。分析结果表明,心脏病专家可以使用提出的工具和方法来调查动脉分叉内的血流动力学状况。

BLOOD FLOW IN CORONARY ARTERY BIFURCATION CALCULATED BY TURBULENT FINITE ELEMENT MODEL
Simulation of blood flow in this paper is analyzed using two-equation turbulent finite element model that can calculate values in the viscous sublayer. Implicit integration of the equations is used for determining the fluid velocity, fluid pressure, turbulence, kinetic energy, and dissipation of turbulent kinetic energy. These values are calculated in the finite element nodes for each step of incremental- iterative procedure. Developed turbulent finite element model, with the customized generation of finite element meshes, is used for calculating complex blood flow problems. Analysis of results showed that a cardiologist can use proposed tools and methods for investigating the hemodynamic conditions inside bifurcation of arteries.
