Blood Flow in a Radially Non Symmetric Stenosed Artery Under Slip Effect Through Porous Medium

A mathematical model is developed to analyze the non-Newtonian flow of blood in an axially symmetric but radially non symmetric stenosed artery through porous medium in the presence of slip velocity. Blood is modeled as Casson fluid to characterize the non-Newtonian behaviour. Flow characteristics like axial velocity, flow rate and impedance are expressed analytically. These expressions show remarkable variations in flow of blood through constricted artery. The effects of porosity, slip velocity and stenosis shape on the various flow characteristics have been examined and shown graphically. These results are in good agreement with the experimental findings existing in the literature and can aid medical practitioner to treat cardiovascular diseases.
