Result The skewed parabolic profile is observed in CCA under 1:60 curvature and physiological average Reynolds number. As curvature and Reynolds number increase, the middle of horizontal profile appears sunken and the vertical profile is M-shaped. There are different profile shapes in different localities along the curved pipe.

结果 当颈总动脉的曲率等于1：60 时，在人生理平均流动雷诺数条件下，颈总动脉的速度剖面可用偏斜的抛物面来近似；当颈总动脉曲率增大或流动雷诺数增大时，弯曲平面上的速度剖面中部出现下凹趋势，垂直方向上出现M型速度剖面；沿管轴不同位置上的速度剖面形状不同。
