Flow of a Micropolar Fluid through a Stenosed Artery with Radially Variable Viscosity
نویسندگان
چکیده
A study of the steady flow of blood through a horizontally symmetric artery with mild stenosis is presented by considering blood as a micropolar fluid. The viscosity of blood is considered as radial coordinate dependent. The non-linear pressure equations governing the flow are solved numerically using finite difference technique. The effects of micropolar fluid parameters and hematocrit on axial velocity, microrotation velocity, wall shear stress, wall couple stress and the volumetric flow rate in the stenotic region and at the maximum height of the stenosis (stenosis throat) have been discussed. The results have been compared with the corresponding flow for a Newtonian fluid.

With an aim to investigate the effect of externally imposed body acceleration on two dimensional,pulsatile blood flow through a stenosed artery is under consideration in this article. The blood flow has been assumed to be non-linear, incompressible and fully developed. The artery is assumed to be an elastic cylindrical tube and the geometry of the stenosis considered as time dependent, and a co...
