摘要: 固体颗粒在垂直管道中的运动是非常复杂的物理过程,对微元体进行受力分析,建立了垂直管道中固体颗粒模型,并用高速摄影仪对颗粒的上升阶段和悬浮阶段进行图像捕捉,得到了固体颗粒的运动轨迹,以此对颗粒运动规律进行了探索。

Abstract: The motion of solid particle in vertical pipeline is a very complicated physical procedure.The paper analyzes the forces acting on the micro unit,and builds the dynamical model of the solid particle in vertical pipeline.Photos are taken when the particles are in the ascent stage and the aerosol stage with the high speed camera.Based on this,the motion path of the solid particle is obtained,and the motion law of particles is explored as well.
