通过水模型实验考察了出流口的大小与形状对游涡临界高度的影响，得出：在出流口面积与出流流量相等的情况下，漩涡的临界高度随出流口的直径（当量直径）的增大而增大；采用缝隙式出流口时产生漩涡的临界高度比采用同面积的圆形出流口时的低得多。这可供进行其它反应器设计时参考。
The effect of the size and shape of the outlet on the critical height of the vortex was investigated by a water model experiment. The results show that the critical height of the vortex is proportional to the diameter of the outlet Diameter) increases; the critical height of whirlpool when using the slit-type outlet is much lower than that when using the circular outlet with the same area. This is for reference when designing other reactors.
