Abstract:

The aim of the present investigation is to develop a mathematical model to study the blood flow in an arterial having overlapping stenosis under the externally applied transverse magnetic field. Blood is modeled as Herschel-Bulkley fluid to represent the non-Newtonian character of blood in small blood vessels. Flow characteristics like for wall shear stress, volumetric flow rate, axial velocity, and core velocity have been expressed analytically and shown graphically. These expressions reveal considerable alterations in flow characteristics due to stenosis shape and magnetic field. The magnetic field perpendicular to the flow of blood is incorporated which significantly controls the flow patterns. The study provides an insight into the effects of magnetic field on flow rate of blood, wall shear stress, axial and core velocities of blood.
