The present study aims to perform computational simulations of two-dimensional (2D) hemodynamics of unsteady blood flow via an inclined overlapping stenosed artery employing the Casson fluid model to discuss the hemorheological properties in the arterial region. A uniform magnetic field is applied to the blood flow in the radial direction as the magneto-hemodynamics effect is considered. The entropy generation is discussed using the second law of thermodynamics. The influence of different shape parameters is explored, which are assumed to have varied shapes (spherical, brick, cylindrical, platelet, and blade). The Crank-Nicolson scheme solves the equations and boundary conditions governing the flow. For a given critical height of the stenosis, the key hemodynamic variables such as velocity, wall shear stress (WSS), temperature, flow rate, and heat transfer coefficient are computed.
