Abstract

The purpose of this work is to simulate and analyse the movement of blood passing from stenosis of an artery of a person with atherosclerosis artery disease. We used three-dimensional modelling and simulation of blood flow through two arteries consisting of two stenosis each, one with the same radius for both the cases and the other with different radii for each case. The type of blood flow was considered to be simple pulsatile in order to mimic the rhythmic pulses of the human heart. The carreau yasuda model was used for the hemodynamic modeling viscosity of fluid and sst (shear-stress-transport) was used as the numerical model. This study considered blood flow models which is non-newtonian and solved the 3D laminar and unsteady NS Equations to extracted velocity profiles at 6 different locations in a blood vessel and shear strain rate for both cases.
