Results show that there is much local secondary flow in square cyclone besides main vortex, such as spiral down-stream near surface and spiral up-steam at central zone.

结果表明：方形分离器内除外涡旋与内涡旋等主流外，还存在许多局部的二次流，这些二次流是影响分离器的分离效率的主要因素之一；结构参数的变化对二次流的强度及位置产生影响，进而影响分离器的分离效率。

Results show that there is much local secondary flow in square cyclone besides main vortex, such as spiral down-stream near surface and spiral up-steam at central zone. The secondary flow is one of the effect factors on the collection performance of square cyclone. The cyclone geometry size affects on the intensity and the position of the secondary flow, and then affects on the separation efficiency of the cyclone.
