Effects of Hematocrit and Heat transfer in Magnetohydrodynamic Blood Flow Through a Vertically Tapered and Overlapping Stenosed Artery

Abstract

This present study discusses the effects of hematocrit and heat transfer in magnetohydrodynamic blood flow in a vertically tapered and overlapping stenosed artery. The mathematical model for the momentum and energy equations was solved. The solutions to the equations governing the motion of the flow in the tapered and overlapping stenosed artery was solved by Differential Transform Method. Different blood parameters were applied to analyse the effects of hematocrit, heat transfer, magnetic parameter on the velocity profile, temperature profile, volume velocity and the wall shear stress of the flow. Results were presented graphically, which show that a rise in hematocrit reduces the velocity profile and the temperature profile of the flow and a rise in the value of either magnetic parameter or porosity hikes the temperature of the flow. The velocity profile and temperature profile increase with rising the values of porosity. The volume velocity increases on the influence of magnetic parameter. Moreover, volume velocity drops under the increase of artery shape. Rises in the value of stenosis height within the range of mild stenosis rises the velocity profile and temperature profile of the flow.
