Irreversibility Analysis and Thermophoresis Effects on Electro-Thermal Blood Flow in a Diseased Artery: A Thermal Case Study

Abstract

This current research explores the numerical solutions of blood flow in a stenotic artery using the Sutterby fluid model to capture the complex rheological behavior of blood. The influence of nanoparticles is incorporated through Buongiorno’s formulation to analyze their effects on flow characteristics. The regulating equations are formulated as a coupled set of partial differential equations, account for nanoparticle dynamics, and are non-dimensionalized under the assumption of mild stenosis. These converted equations are numerically resolved utilizing the finite difference method in MATLAB. A finite difference scheme is employed to achieve computational solutions, enabling the examination of velocity, temperature, mass concentration, entropy production, wall shearing stress, flow rate, and resistance. The findings indicate that an improvement in the thermophoresis parameter enhances blood velocity and significantly affects nanoparticle distribution. Graphical analyses further illustrate the influence of various factors on flow behaviour, providing insights into the interplay between stenosis, nanoparticles, and physiological blood transport. The study contributes to a better understanding of blood flow dynamics in diseased arteries, which may aid in optimizing treatment strategies and biomedical applications.
