颗粒在圆形偏心滚筒内的运动模式
Motion mode of particles in a circular eccentric drum
摘要
Abstract
Experiments were conducted to study the factors which affect motion state of particles in a circular eccentric drum,and the effects of two offsets,four filling rates and four rotating speeds on the motion model were analyzed. Rotating speed and filling rate were the main factors affecting the change of the motion model of particles in a circular eccentric drum,while offset had no effect. Filling rate did not have an impact on the motion model of particles at rotating speed of 15r/min and 25r/min. But when rotating speed was 5r/min,the motion model of particles varied from slumping mode to rolling mode accordingly when filling rate increased from 1/6 to 1/3,and when rotating speed was 40r/min, the motion model of particles varied from rolling mode to cascading mode accordingly when filling rate increased from 1/6 to 1/3. With increasing offset,vortex core generated in the process of movement deviated more from the center of the drum. Increasing rotating speed resulted in the change of the upper surface of particle group and the arc of the falling particle group on both ends. The effect of filling rate on the motion model of particles occurred only at low and high rotating speeds.关键词
