Response to blood flow through a overlapping stenosis in catheterized arteries

Abstract

The present work concerns the effects on the flow characteristics of blood due to the presence of an overlapping stenosis in an artery assuming that the flowing blood is represented by a Newtonian fluid. The expressions for the blood flow characteristics-the impedance, the wall shear stress distribution in the stenotic region, shearing stress at the stenosis throats and at the stenosis critical height have been derived. Results obtained have been displayed graphically and discussed briefly
