At the carotid bifurcation, the risk factor increases as a result of changes in the flow of blood and phenomena such as flow separation, the rotating flow, and the effects of the shear stress caused by the walls, which all contribute to an increased risk of injury. This raises the likelihood that the carotid artery will be damaged. In this regard, the current study numerically replicates the pulsatile blood flow in an elastic carotid artery particular to a patient using physiological pulses, non-Newtonian models, and turbulent models. The outcome of wall shear stress demonstrated how much more significant rigid or elastic walls are than Newtonian or non-Newtonian blood, which is more significant than laminar or turbulent flow. The critical pressure in the Carreau model is higher than that in the Newtonian model, which is higher than that in the Power-law model, according to comparisons made between other non-Newtonian models and the Newtonian one.
