Mathematical Model of Bingham Fluid Inside Asymmetric Stenosed Artery and Its Applications

This study is to analysis the two-layered model of blood flow inside asymmetric stenosed artery with the consideration that blood behaves like a Newtonian and non-Newtonian fluid with different viscosities in the Peripheral layer and core regions. Further, in view of the existence of a velocity slip in blood flow regime, an axial slip condition as reported by many researchers is introduced at interface of the two-layers in the present analysis. The expressions for the flow characteristics namely the velocity profile, flow rate , the resistance to flow, the wall shear stress at the stenosis throat within the tube are obtained. Discussions are done from a physiological point of view with the help of graph.
