In the multiple turbulent jet-to-crossflow, the"hole inhale phenomenon"is more obvious in the lee of the first jet orifice. We got the vortex fields of the multiple turbulent jet-to-crossflow in different conditions. The developing processes of horseshoe vortex and kidney counter-rotating vortex pair are studied. The results suggest that in the multi-hole jet, until the multi-hole jet merging into a new jet, the miniature of horseshoe vortex appears, and the shape of CVP changes regularly.

由于流体与双侧壁面之间的摩擦造成能量损失和湍流能量耗散，导致最大切向速度不断衰减且位置沿轴向向下逐渐向提升管外壁移动，同时涡量传递造成外部的准自由涡区逐渐增大，内部的准强制涡区逐渐缩小。

The swirling flow inside the cyclone showed the Rankine vortex characteristics, i e, strong swirling vortex at the central region of the cross-section and weak swirling quasi-free vortex near the wall.

方形旋风分离器内的流动具有Rankine涡的特点，即中心部分为强制涡区，边壁附近是准自由涡区。
