Computational Analysis of Blood Flow in a Curved Bifurcated Coronary Artery

Abstract

Nowadays, Cardiovascular Diseases (CAD) are very prominent in many countries. Lot of research is going on in the medical field for finding the best solutions and cures to these diseases. Bifurcation of the arteries is one of the most common reasons for these Cardiovascular Diseases. The damages caused due to the bifurcation of the arteries have a great impact on the flow variables of the blood. In this study, by using the Autodesk Fusion360 the geometry has been created. There are two models based on the angle of bifurcation of the artery and the number of the bends. The flow analysis of the fluid has been done using the ANSYS FLUENT software which is one of the most popular software used by the solvers for Computational Fluid Dynamics (CFD). In the first model the bifurcation angle is 70o and there are two bends. And in the second model the bifurcation angle is 50o and it contains a single bend. This study helps us to know about the change of flow variables of the fluid like velocity, wall shear stress (WSS), pressure as the flow passes through the bifurcation region. It was found that the recirculation increased as the angle of the bifurcation increased
