The current study presents three-dimensional modelling and analysis of blood flow through carotid artery bifurcation in multiple cases hemodynamics modelling of fluid viscosity. The study considered Newtonian and non-Newtonian blood flow models and solved the three-dimensional laminar and steady Naiver-Stokes (NS) equations for different inlet velocity profiles. Two methods were used to define dynamic viscosity the Carreau Yasuda model and power law non-Newtonian. A comparative analysis was carried out for Newtonian and non-Newtonian fluid models under simple pulsatile, equivalent pulsatile and physiological velocity profiles. The non-Newtonian model in Carreau and power law non-Newtonian showed a higher central velocity than the Newtonian model about 10%. The non-Newtonian model showed 80% higher Wall shear stresses, either the pressure results on the arterial wall were similar in all models.
