Abstract
It is known that the stenosis in the artery is responsible for changing the nature of blood flow from its usual state. Therefore, the flow of blood through a cosine-shaped stenosed artery has been investigated, treating blood as Casson fluid. The effects of stenosis height, viscosity, slip velocity and yield stress on blood flow has been obtained. The results have been highlighted that the axial velocity, volumetric flow rate, pressure gradient and wall shear stress decrease with the increasing of viscosity and yield stress but these increases with the increasing of slip velocity. The results have been presented graphically for a better understanding by choosing the suitable parameters.
