Abstract
To help us understand the details of pulsating blood flow through the post-stenotic dilatation artery we use the computational fluid dynamic techniques to gain the wall shear stress distributions and the streamline patterns. In the work, a mathematical model of the axially symmetric rigid artery containing the stenosis and the dilatation is introduced. The incompressible Navier-Stokes equations are solved numerically by using the finite difference method. The geometry and the flow conditions represent a real physiological situation as closely as possible.
