Numerical and Experimental Investigation of Hemodynamics of Blood Flow through Realistic Stenosis

The present study investigates the flow through the actual stenosed artery due to the Atherosclerosis، both numerically and experimentally. The governing differential equations of blood flow are solved by controlvolume techniques in the generalized body-fitted coordinates because of the complex geometry. The aim of this study is isolate the effect of actual stenosed geometry on the flow characteristics such as، velocity and pressure profiles، velocity vectors and mean and local wall shear stress in the post-stenotic. It is shown that the oscillation and sudden increase of wall shear stress is found to relate to the increasing Reynolds number at the neck of stenosis، which is an important factor in progress of arterial disease.
