Magnetohydrodynamic (MHD) of Blood Flow in a Stenosed Artery

This research modeled MHD third grade blood flow in a three layered stenosed artery. The most important rheological properties of blood, such as viscosity and the density have been modeled into the shear thinning/thickening parameters. Regular perturbation method was used to obtain the flow characteristics such as the flow velocity, the volume flow rate, the shear stress and the resistance to the flow. We considered a three layered stenosed artery of about 6unit length. We reduced the model into dimensionless parameters, hypothetical values were used. The obtained results showed that, the volume flow rate and the velocity increases with increase in the magnetic field intensity Hand the shear thinningΛ_1and reduces with increase in the shear thickening Ω_1. The resistance increases with increase in the shear thickening Ω_1 and decrease with increase in magnetic field intensity H and the shear thinning Λ_1.
