Numerical simulations of cardiovascular flows have emphasized investigating the mechanics of blood flow in arteries. The objective of the current study is to examine the effect of Newtonian and non-Newtonian flow models in flow simulation to analyze for hemodynamic behavior. CFD analysis was performed on an idealized healthy abdominal aorta with renal branching using ANSYS Fluent solver. The discretized mesh was obtained having polyhedral and hexahedral grid ensured the capture of gradients with a sufficient number of grids. Transient analysis was performed using pulsatile flow boundary conditions. Velocity plots obtained from the analysis predict the recirculation zone in the Ostia of the renal artery. TAWSS observed to be maximum at the infrarenal aorta. And Newtonian model predicted higher TAWSS. Oscillatory shearing index calculated to be maximum at the bifurcation. The result of this analysis will be helping in understanding the flow behavior in idealized cases and further extended to stenosed cases.
