Analysis of Pulsatile Magnetohydrodynamic (MHD) Third Grade Blood Flow in a Stenosed Artery

摘要

In this research, we modeled MHD third grade blood flow in a stenosed artery. The blood viscosity and the density have been modeled into the shear thinning/thickening parameters, the most important rheological properties of blood. We used regular perturbation method and obtained the flow characteristics such as the flow velocity, the volume flow rate, the shear stress and the resistance to the flow considering a single layered stenosed artery. The results however showed that there is significant increase in volume flow rate and the velocity with increase in the magnetic field intensity style="font-family:Verdana;"> style="font-family:Verdana;">H style="font-family:Verdana;"> style="font-family:Verdana;"> and the shear thinning style="font-family:Verdana;"> style="font-family:Verdana;"> style="font-size:9.0pt;font-family:;" "="">Λ style="font-family:Verdana;"> and reduces with increase in the shear thickening style="font-family:Verdana;"> style="font-family:Verdana;"> style="font-size:6.5pt;font-family:;" "=""> style="font-family:Verdana;font-size:8.66667px;white-space:normal;">Ω style="font-family:Verdana;">.
