Abstract

We present a study on Bingham characteristics of blood flow through an arterial segment with multiple overlapped stenosis with no or negligible stenosis distance. The case is considered to be chronic, as almost every point on the wall is affected. Empirical Analysis was carried out to illustrate the effect any significant change in the stenosis shape, stenosis height and the parameter γ has on the resistance to flow. The results are presented graphically. It was found that a small increase in the stenosis height brings about high resistance to the blood flow as it narrows the flow region. Similarly, an increase in the stenosis shape parameter causes an increase inshear stress with the magnitude of increase being greater for small values of
