反应器中出流口的大小和形状对漩涡临界高度的影响

Influence of the Area and Shape of Outlet on the Critical Height of Vortex Sink

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。

This paper has investigated the influence of the area and shape of outlet on the crit-ical height of vortex sink by water model trails and got these results as: (1) the critical height of vor-tex sink varies consistent with the diameter of outlet when the experimental condition is same; (2)Using slit ouilet, the critical height of vortex sink is substantially lower than that of the round outletused when the area of outlet and flow are equal. It can help to design other rectors.
