ABSTRACT
To study the effect of magnetic field of blood flow through stenosed vessels, a numerical model has been developed. The blood is assumed to be an incompressible Newtonian fluid. The effect of slip at the boundary in presence of transverse magnetic field, momentum and energy integral equation is used. The problem under investigation is solved numerically using Shooting method. It is assumed that when the Hartmann number increases the fluid velocity and the wall shear stress is greatly affected. It is observed that the centerline velocity U decreases with increasing Reynolds number at M=1.5. The nature of U is also same with no slip. Moreover, the centerline velocity U increases when the Hartmann number increases with slip at Re=50 and in no slip case. On the other hand, it is seen that when Hartmann number increases, the axial velocity (v) decreases in both with slip and in no slip condition. In contrast, the axial velocity increases when Reynolds number increases with slip. Similar phenomena observed in no slip also.
