This study focuses on the behavior of blood flow in the stenosed vessels.
Blood is modelled as an incompressible non-Newtonian fluid which is based on the power law viscosity model.
A numerical technique based on the finite difference method is developed to simulate the blood flow taking into account the transient periodic behaviour of the blood flow in cardiac cycles.
Also, pulsatile blood flow in the stenosed vessel is based on the Womersley model, and fluid flow in the lumen region is governed by the continuity equation and the Navier-Stokes equations.
In this study, the stenosis shape is cosine by using Tu and Devil model.
Comparing the results obtained from three stenosed vessels with 30%, 50%, and 75% area severity, we find that higher percent-area severity of stenosis leads to higher extrapressure jumps and higher blood speeds around the stenosis site.
Also, we observe that the size of the stenosis in stenosed vessels does influence the blood flow.
A little change on the cross-sectional value makes vast change on the blood flow rate.
This simulation helps the people working in the field of physiological fluid dynamics as well as the medical practitioners.
