dc.description.abstractBlood flow in arterial vessels exhibits complex non-Newtonian behavior, especially under pathological conditions such as obesity. Obesity is a major risk factor for the development of cardiovascular diseases, as it contributes to the accumulation of fat in the arterial walls, ultimately leading to the narrowing (stenosis) of blood vessels. In this study, the Casson model is employed to analyze pseudoplastic blood flow in the abdominal artery with varying degrees of stenosis at 25%, 50%, 75%, and 90%. Simulations were conducted using COMSOL Multiphysics software to evaluate the velocity distribution and flow patterns resulting from narrowing caused by fat accumulation. The simulation results indicate that higher degrees of stenosis lead to increased maximum blood flow velocity in the stenotic region. This occurs due to elevated pressure and flow acceleration resulting from the reduced arterial cross-sectional area. Furthermore, downstream of the stenosis, the blood flow pattern changes significantly, with the potential formation of recirculation zones, which may contribute to an increased risk of cardiovascular complications in individuals with obesity. This study provides valuable insights into the effects of obesity-induced stenosis on blood flow dynamics and demonstrates that the Casson model is a suitable approach for understanding such phenomenaen_US
