Abstract

The present study is analysis of non-Newtonian blood flow through stenosed vessel in porous medium. The blood is assumed to be pulsatile couple stress fluid. The effect of externally applied magnetic field on blood flow in porous medium is studied in the present analysis. The expressions of axial velocity, flow rate and shear stress have been obtained by using Laplace and finite Hankel transforms and their graphical interpretation has been discussed. The results obtained have been compared with previous studies in special cases and found to be in good agreement with other theoretical results.

Key words: Stenosed vessel, couple stress fluid, magnetic field, porous medium, finite Hankel transform, Laplace transform, axial velocity, shear stress.
