A COMPREHANSIVE STUDY ON CFD ANALYSIS OF BLOOD FLOW IN ARTERIES

Abstract

Blood flow in a living organism is an unsteady and complex phenomenon. Blood vessels have geometrical features like curvature, bends, branching, Y-intersection, variations in the diameter of the vessel and the most important, pulsatile nature of the blood. Cardiovascular diseases are most Common in the world today that is fatal for mankind. Therefore, it is very important disease from public health and individual standpoint. So, it is vital to study the parameters that affect flow of blood in arteries [1]. We study the Newtonian nature of blood using patient specific data extracted using MRI or CT scan and applying these boundary condition in the flow simulation. ANSYS Fluent software is used to examine all of the cases comprising bend in artery, Y intersection and bifurcating artery. We examine the wall shear stress profile and velocity profile for all these cases separately before we integrate them together.
