  In this article, effects of heat transfer on MHD blood flow through a
stenosed inclined porous artery with heat source have been investigated. The
viscosity of the blood is assumed to be varying radially with hematocrit
throughout the region of the artery. Governing equations have been derived by
treating blood as incompressible magnetohydrodynamic (MHD) Newtonian fluid.
Momentum and energy equations of the fluid flow are simplified under the
assumption of mild stenosis. Homotopy perturbation method (HPM) is used to
solve nonlinear differential equations for velocity and temperature profiles of
the blood flow. Variation of flow rate and shear stress for different values of
inclination angle and hematocrit parameter along the diseased part of artery
have been plotted graphically. For having the adequate insight of the flow
pattern in the diseased artery, velocity contours have been plotted for
different values of the height of the stenosis and for different inclination
angles of the artery.
