Mathematical Modelling of Two Layered Blood Flow through a Tapered Artery with Overlapping Stenotic Condition

Abstract

This study deals with the effects of overlapping stenosis on flow rate, resistance to flow and wall shear stress in a tapered artery for different parameters. A two layered mathematical model has been included here by considering the peripheral layer as Newtonian fluid and the central core layer as Bingham plastic type non-Newtonian fluid. The numerical results are presented in graphical form and discussed. It was found that volumetric flow flux reduces as overlapping stenosis height increases and resistance to flow rises with increase in stenosis height and values of artery shape φ.
