摘　　要：运用计算机数值试验与实验结合的方法对圆环管煤粉浓淡分离器的设计过程进行了研究。对分离器的挡环角度的变化、分隔环位置变化、速度平衡环的作用进行数值试验，得到了不同工况下的两相流场，总结出对设计有用的规律。部分结果与实验值进行比较，与实验值相符。其结果对分离器的设计有辅助优化作用。Abstract: The numerical simulating approach was used for designing of fine coal ring shaped separator, based on solid gas two phase flow theory. The angles α and β of densifing ring, the set of separating ring shaped wall and the height of velocity balance ring were tried by numerical simulating. The numerical results were compared with experimental results and showed good agreement with experimental results. Many available conclusions which can optimize designing were given.
