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。
通過對不同轉速下鏇轉圓桶水流中固體顆粒運動進行試驗,利用高速攝像機捕捉試驗中固體顆粒的運動軌跡,研究固體顆粒在鏇轉流中二維受力情況,併對其徑嚮嚮心運動現象的普遍性和規律性進行瞭初步驗證。研究錶明,在低速轉動圓桶水流中固體顆粒運動所受差異鏇轉慣性力與阻力所佔比例遠大于固體顆粒所受離心力和虛假質量力所佔的比例。

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.
