Mathematical Modeling for Casson Blood Flow in Stenosed Arteries: A Comparative Study

Abstract

Cardiovascular diseases are the leading cause of mortality worldwide. A significant contributor to these conditions is arterial stenosis, which disrupts normal blood flow and increases the risk of critical events like myocardial infarction and stroke.

This study explores the dynamics of blood flow in stenosed arteries using the Casson fluid model to capture its non-Newtonian properties. Focusing on arteries narrowed by plaque accumulation, the study examines the effects of critical parameters such as different stenosis geometries on hemodynamic behaviour. Employing the numerical approaches, the findings reveal significant deviations in velocity profiles in different degree of stenosis. The study provides valuable insights for improving diagnostic and therapeutic strategies in cardiovascular care.
