MATHEMATICAL AND COMPUTATIONAL STUDY OF BLOOD FLOW THROUGH DISEASED ARTERY

Abstract This paper presents the study of blood flow through a tapered stenosed artery. The fluid (blood) medium is assumed to be Power law fluid model. The governing equation for laminar, incompressible and non-Newtonian fluid subject to the boundary conditions is solved by using a well known perturbation mathematical method. The analytical expressions for velocity component, volumetric flow rate, wall shear stress and pressure gradient are obtained. It is observed that the shape of artery have important impact on the velocity profile, pressure gradient and wall shear stress. It is also found that wall shear stress increases when peak is obtained then decreases for different values of tapering angle.
