Mathematical model for bingham flow properties of blood in uniform tapered tube

The stenosis and non-Newtonian property of the fluid in the blood flow represent the behavior of Herschel-Buckley fluid.In a tapered tube model all the vessels which carry blood towards the tissues are considered as long and its one end slowly tapering cones rather than cylinders. Since the blood flow consist of two regions in which one is central region, consist of concentrated blood cells and its behavior is non-Newtonian and other region is periph-eral layer of plasma which represent the Newtonian behavior of fluid motion. In present paper, we have considered the Bingham fluidmodel and study the flow of blood in a uniform tapered tube and obtained conditions and its variation in various graphs for shear stress and pressure gradient.
