Numerical Investigation Of Permeability Effects On Blood Flow In A Stenosed Artery Using The Crank-Nicolson Method

Abstract

The flow dynamics in a stenosis artery with an obstruction are solved using a finite difference technique in this study, taking the permeability parameter's effects into account. The Crank-Nicolson method is used to solve the governing equations. With special attention to the impact of porosity, the results are interpreted in the context of blood flow through a stenosis artery. High shear stress is unlikely to cause atherosclerotic lesions, according to quantitative numerical models for both steady and pulsatile flows. The role of porosity is found to be significant, especially in conditions related to cholesterol accumulation and related arterial diseases.
