Computational Analysis of Non-Newtonian Blood Flow through Bifurcated Coronary Artery: Insights into Hemodynamics and Wall Shear Stress
Abstract: This abstract presents a study on the computational fluid dynamics (CFD) simulations of blood flow through a bifurcated coronary artery using non-Newtonian fluid model. The objective of this study is to investigate the hemodynamic characteristics in Bifurcated Coronary artery. The methodology involved the utilization of ANSYS SpaceClaim software for creating a geometric model of the bifurcated coronary artery. A mesh independent study was conducted to ensure the accuracy and reliability …

Revealing the Hemodynamic Orchestra: Contrasting Analysis of Blood Flow Patterns in a Bifurcated Carotid Artery
Abstract: Understanding blood flow patterns in the carotid artery (CA) is crucial for detecting cardiovascular diseases. Computational fluid dynamics simulations compared non-Newtonian (non-Newt) and Newtonian (Newt) models under pulsatile and laminar flow. CA geometry was accurately designed using ANSYS Space Claim & Fusion360, and simulations were run in ANSYS Fluent. Discrepancies between non-Newt and Newt models were found, especially in bifurcation's distal regions prone to plaque. Pressure ranged from 27.870 Pa …

Mathematical Modelling on Unsteady Blood Flow and Unsteady Heat Transfer Through a Stenosed Artery with Hematocrit and Slip Velocity
Abstract: A theoretical investigation concerning variable viscosity dependent on percentage concentration of red blood cell interm of total volume of blood (hematocrit) and slip velocity on unsteady flow of blood and heat transfer has been carried out. The analytical expressions for the flow characteristics and the heat transfer rate, including the velocity profile, volumetric flow rate, flow resistance, wall shear stress, and temperature profile, were obtained using the weighted residual method, …
