Investigation of Pulsatile Behavior and Flow Characteristics in Stenosed Arteries: Analysis of Bingham Plastic Fluid Dynamics

Anurag Singh

Abstract: This work delves into the effects of Bingham plastic fluid flow within stenosed arteries, employing two-layer model to examine the pulsatile behavior of fluid within artery. Utilizing perturbation techniques, the study addresses velocity, shear stress, and flow rate. Graphical representation of outcome indicates a decrease in velocity with increasing radius, alongside an increase in flow resistance over time. These findings enhance our understanding of fluid dynamics in stenosed arteries, with potential implications for the diagnosis and treatment of cardiovascular diseases, particularly atherosclerosis, characterized by plaque buildup and arterial blockages. The graphs illustrate that as the radius of the artery increases, the velocity of the fluid flow decreases. This suggests that narrower arteries experience faster blood flow compared to wider ones. Additionally, the graphs show that over time, there is an increase in resistance to flow within the stenosed arteries. This implies that as arterial stenosis progresses or persists, the resistance to blood flow also increases. Understanding these dynamics is crucial for gaining insights into how blood flows through stenosed arteries, which is relevant to cardiovascular diseases such as atherosclerosis. Atherosclerosis involves the buildup of plaque in the arteries, leading to narrowing or blockage of blood vessels. The findings from this study contribute to our understanding of how blood flow is affected by arterial narrowing, which can inform diagnostic methods and treatment strategies for cardiovascular diseases. Therapies aimed at reducing arterial stenosis or managing its effects may benefit from considering the dynamics of fluid flow within stenosed arteries.
