Numerical Simulation to Investigate the Effect of Non Newtonian Properties of Blood on Wall Shear Stress in Diseased Artery
Wall Shear Stress (WSS) in the artery is one of the indicators for brain artery disease progression. WSS is proportional to the viscosity and shear rate of the flowing fluid. In this study, WSS of cerebral artery with aneurysm was predicted using Computational Fluid Dynamics (CFD). The effect of...

| Summary: | Wall Shear Stress (WSS) in the artery is one of the indicators for brain artery disease
progression. WSS is proportional to the viscosity and shear rate of the flowing fluid. In this study,
WSS of cerebral artery with aneurysm was predicted using Computational Fluid Dynamics (CFD).
The effect of non-Newtonian properties of blood will be studied by comparing Power law model
with Newtonian model. Based on the results, maximum value of WSS is 150 Pa for Newtonian
model and for Power Law model is 24 Pa. Newtonian model was found overpredicted the WSS
resulted from Power Law. |
