Abstract:
BACKGROUND:To establish the real body’s artery model has its own limitations due to the diversity of different individual differences in the carotid artery and blood flow.
OBJECTIVE:To study the effect of different inlet velocity profiles of the common carotid artery and three different flow ratios of internal and external carotid artery on hemodynamics of the carotid artery.
METHODS:The carotid bifurcation TF-AHCB numerical model was established. Commercial software ANSYS was used to compute the flow field and calculate hematodynamic parameters, including velocity and wal shear stress. Then, their relationship with atherosclerosis was analyzed from different angles.
RESULTS AND CONCLUSION:Flow ratio of internal and external carotid artery significantly influences the flow field of the simulated bifurcation of the carotid artery. Changes in the magnitude of inlet velocity cannot only alter the hematodynamic properties, but also change the range of mechanical mechanism.
