The present study deals with blood flow through an arterial segment with overlapping stenosis depending on time to a certain extent. The problem is examined by a combined effort of analytical and numerical techniques. The influence of time and slip velocity on wall shear stress, resistance to flow, axial velocity and volumetric flow rate are expressed(More)
In the present investigation, a mathematical model is developed to study the flow of blood in a multiple stenosed artery employing velocity slip condition 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. The expressions for wall shear(More)
