Numerical Analysis of Blood Flow through Blood Vessels with Atherosclerosis Using the Newtonian Flow Model

This study quantitatively investigates a Newtonian model for blood flow in a human blood vessel with an atherosclerotic artery. For numerical investigation, the Newtonian flow model of blood flow is used. COMSOL Multiphysics is used for the simulation of the model. The governing equation system, that is depends on incompressible Navier-Stokes equations, considers blood characteristics. Examining the blood flow pattern through an atherosclerotic artery is the aim of this investigation. To solve the governing system of equations with boundary conditions, the finite element model by COMSOL Multiphysics is used. The results have been shown concerning velocity, pressure, and streamlines. Graphical cross-sectional maps of velocity magnitude, pressure, and streamline over the atherosclerotic contraction are also shown. The blood flow simulation findings indicate that the blood flow velocity rises near the plaques. This paper will analyze how the quantity of atherosclerotic plaque controls blood flow through an atherosclerotic artery, assuming the flow is steady and the blood is treated as Newtonian Fluid Model.
