A Study of the Blood Flow Using Newtonian and Non-Newtonian Approach in a Stenosed Artery

In the present work, a brief survey has been made on the Newtonian and non-Newtonian approach of blood flow in a step like stenosed artery. A comprehensive theoretical study on the relation between the shear rate and the viscosity of the fluid has been carried out in the case of each non-Newtonian model (e.g. Maxwell fluid model, Casson fluid model, Carreau model, etc.). In this paper, we have considered a backward-facing step for simulation of the blood flow by employing a few of the above-mentioned models. The simulation is performed by using the available CFD package. © 2021, Springer Nature Singapore Pte Ltd.
