Abstract

In this paper the mathematical model has been developed to evaluate wall shear stress in the stenosis of artery. The artery
is modeled as symmetric stenosis vessel; also the flow of blood is modeled as an incompressible Newtonian fluid. The
results show that shear stress have direct proportional relation with both length and height of stenosis. This mathematical
model is a useful and a simple toll to evaluate wall shear stress of patients with stenosis artery disease.
