Abstract

This article analyzes the bifucate Y-type coronary artery based on hemodynamics and computational fluid dynamics to study the optimal location for thrombosis. Mathematical derivation is used to analyze the fluid machanics. The issue of fully developed flow is derivated. The optimal location for thrombus is identified. According to the mathematical derivation and numerical modeling results, the optimal location for thrombus is at the bifurcation of coronary artery. Vortex and turbulent fluctuation will take place. Three bifurcate angle (60, 90 and 120) is chosen to analyze by numarical stimulation. The result shows that vortex at bifurcation area grows when the bifrucate angle increases. It may cause the sediment of blood platelet, fibrous protein and lipochondrion [1]. It is also concluded that the wall shear stress is so high that it may injure the vascular wall around bifurcation.
