TWO-PHASE MODEL FOR THE STUDY OF BLOOD FLOW THROUGH STENOSED ARTERY

In this present study the influence of peripheral layer viscosity on physiological characteristics of blood flow through stenosed artery using Power–law fluid model is investigated. The hemodynamics behavior of the blood flow is influenced by the presence of the arterial stenosis. If the stenosis is present in an artery, normal blood flow is disturbed. The non-linear pressure equations have been solved with help of boundary conditions and result are displayed graphically for different flow characteristics. It is found that the resistance to flow decreases as stenosis shape parameter increases and increases as stenosis length, stenosis size, peripheral layer viscosity increases. Comparisons between the measured and computed peripheral layer viscosity profiles are favorable to our solutions. For the validation of numerical model, the computation results are compared with the experimental data and results from published literature.
