ABSTRACT
ABSTRACT: The present work is a numerical simulation of the blood flow around the atherosclerotic plaques in a two dimensional straight stenosis vessel. With assuming the plaque as a homogenous porous medium, the governing continuity, NavierStokes, Brinkman Forchheirmer and energy equations are solved simultaneously. This analyze characterizes the effect of plaque porosity on the temperature heterogeneity and likelihood of vessel rupture. It was shown by diseases development and decreasing porosity from 0.8 to 0.4, the maximum plaque surface temperature increases 90% and also 2.35 times higher shear force is exerted to the distal region.
