Numerical Analysis for the hemodynamics mechanism of a curved artery having multiple stenosis

Abstract

Abstract The surgical intercede firstly requires the spotting and quantification of stenosis. The analysis of blood flow in such arteries lead to the prediction of hemodynamics mechanism in these diseased arteries. It is further helpful in designing the devices that imitates the blood flow and in diagnostic tools formation. The hemodynamics mechanism of a curved artery having multiple stenosis is interpreted. An exact as well as a numerical solution approach is utilized in the present analysis. Since blood flow is usually turbulent in such stenosed arteries and the advantage of using numerical approach is that we have also considered the turbulent flow phenomena in this curved artery. Exact solutions provide the line graphs for this flow problem while the numerical simulations are obtained by using the free source OPENFOAM software. The numerical approach is more convenient to consider the desirable location of stenosis. It means that we can construct various complex geometries with multiple locations of stenosis more conveniently by using the numerical approach.
