摘  要:
建立了单一颗粒在对撞流中运动的动力学模型 ,推导了物料颗粒在不同流动状态中滞留时间及运动轨迹长度的计算公式 ,并给出计算实例 ,最终得出颗粒在对撞区中的运动情况。通过对单一颗粒运动的理论分析 ,得出颗粒在对撞区中的振荡运动受加速管中气流速度和加速管长度的影响 ,为对撞流干燥器的设计提供了初步的理论依据

摘  要:
In this paper,a dynamic model for a single particle movement in impinging stream was developed. The formulas of particle residence time and movement track length in different flow type area was deduced and a count example was given. Finally,the status of a particle movement in impinging area was predicted. According to theoretical analysis of a single particle movement,it was educed that the particle oscillation in impinging zone was affected by airflow speed in the accelerating tube and the length of the tube.
