One of the most prevalent symptoms of cardiovascular disease, which remains a major global health concern, is arterial stenosis. In order to effectively diagnose and treat tapering arterial stenosis with dilatation, it is essential to understand the hemodynamic changes that occur. In order to thoroughly evaluate the fluid dynamics in these vascular situations, this work takes a complex approach by using the Ellis fluid biorheology model. A complex geometric structure seen in numerous vascular diseases is the tapering arterial stenosis with dilatation. Using computational fluid dynamics (CFD) models, the research aims to clarify the complex relationship between fluid rheology and vascular shape. In contrast to more conventional Newtonian models, the Ellis fluid model more accurately depicts blood rheology by taking into account the non-Newtonian behavior and shear-thinning characteristics of blood. This research takes a methodical look at how hemodynamic factors such wall shear stress, velocity profiles, resistance to flow, and volumetric flow rate are affected by different levels of yield stress, shape parameter, and viscosity coefficient. The results show how important it is to take non-Newtonian factors into consideration when trying to foretell the hemodynamic effects of tapering arterial stenosis with dilatation. In addition, the study delves into the possible clinical consequences of these hemodynamic changes, with the goal of enhancing our knowledge of disease development and directing tailored treatment approaches. This research highlights the significance of including realistic biorheological factors in a thorough understanding of vascular pathophysiology and provides valuable insights into the hemodynamics of tapered arterial stenosis with dilatation by combining advanced computational models with clinically relevant geometric variations. These findings have the potential to lead to better methods of diagnosis and more efficient treatments for cardiovascular illnesses.
