Blood flow Obeying Casson fluid Equation through an artery with radially non-symmetric mild stenosis

TLDR: In this paper, the authors dealt with blood flow through a radially non-symmetric stenosed artery and found that the resistance to flow increases as stenosis height increases and decreases with stenosis shape.

Abstract: The present paper deals with blood flow through a radially non-symmetric stenosed artery. Blood has been assumed to be a non-Newtonian fluid obeying Casson fluid. It is found that the resistance to flow increases as stenosis height increases and decreases as stenosis shape increases. It is also observed that resistance to flow increases as yield stress, blood viscosity and flux increases. The variat ions of wall shear stress with axial distance for different values of stenosis shape ( s ) has been shown graphically Keywords— Casson fluid, yield stress, Viscosity, resistance to flow, wall shear stress, flow, shape parameter
