Analysis on Rheology of Unsteady Casson Fluid Flow through an Atherosclerotic Lesion

Abstract

In this study, the blood flow mechanism in an inclined artery with the unwanted growth inside the arterial wall has been investigated by modelling blood as a non-Newtonian Casson fluid. A significant quantitative investigation on various flow physical parameters, including axial velocity, volumetric flow rate, plug core radius, plug core velocity, wall shear stress, and effective viscosity, has been analyzed through numerical calculations under the assumption that blood flow is unsteady. According to this study, slip velocity, inclination, yield stress, stenosis height and Reynolds number all have made a considerable impact on flow characteristics during blood flow in the core region.
