中文摘要：

通过对不同转速下旋转圆桶水流中固体颗粒运动进行试验，利用高速摄像机捕捉试验中固体颗粒的运动轨迹，研究固体颗粒在旋转流中二维受力情况，并对其径向向心运动现象的普遍性和规律性进行了初步验证。研究表明，在低速转动圆桶水流中固体颗粒运动所受差异旋转惯性力与阻力所占比例远大于固体颗粒所受离心力和虚假质量力所占的比例。

Abstract： Through tests by rotating cylindrical solid phase particles movement of different speeds and using high-speed cameras to capture test the method of solid-phase particles trajectory, it studied the solid phase particles in the rotational flow in 2D by force, and preliminary validation of its radial to the universality and regularity of the heart movement phenomenon. The studies show that the difference in the rotational inertia force and resistance in the low-speed rotation of the disc-liquid flow in a single particle movement suffered proportion are much larger than the solid-phase par- ticles affected by centrifugal force and false mass force proportion.
