BLOOD FLOW RESISTANCE FOR A SMALL ARTERY WITH THE EFFECT OF MULTIPLE STENOSES AND POST STENOTIC DILATATION

An attention for the effect of a post stenotic dilatation and multiple stenoses on an arterial blood flow is made through this work. The resistance to flow ratio is investigated with the different values of yield stress, viscosity, and the flux. For this study we consider fully developed, one-dimensional non-Newtonian fluid namely Bingham plastic fluid flow through a single vessel. The radius of vessel is varying. The formula for the resistance to flow is determined and the results are found for the yield stress, viscosity and flux. The numerical values of the resistance to flow ratio vary from maximum radii of the two abnormal segments to the minimum radii.
