Slip Velocity Effect on Blood Flow through a Multi-Irregular Constricted Artery

Abstract

In this research paper, fluid flow is considered in uni direction through the multi – irregular constricted artery. Blood has been considered Hershcel –Bulkley i.e. non- Newtonion. Analytical techniques are carried out to solve the problem. Mathematical expressions for several variables of fluid flow has been estabilished. The effect of slip velocity, flow behaviour index and yield stress on axial velocity volumetric flow rate and wall shear stress have been depicted through graphs. It has noticed that velocity in axial direction and fluid flow rate increases as increase in slip velocity at arterial wall. It has also observed that shear stress increases with increasing of yield stress. Flow rate reaches lowest value at some points in the portion of stenosis for clinical investigation.
