针对深孔泄水道中的两道平面闸门槽,给出了两种常见门槽体型在不同的槽间距情况下的流场压力分布和流速分布的风洞试验结果。并将风洞试验结果与水洞中获得的水流空化试验结果作了对照分析。结果表明:在一定范围内,双门槽间距的改变对水流空化状态乇显著影响。深孔泄水道中两道门槽的中心距以2.5～5.0倍槽宽为宜。
According to the two flat gate slots in the deep-water drain channel, the wind tunnel test results of the flow field pressure distribution and the flow velocity distribution of the two common gate slot types with different slot spacing are given. The results of wind tunnel test are compared with those of cavitation in water tunnel. The results show that: within a certain range, the change of the spacing of double gate slot has a significant effect on the torch cavitation state. Deep hole drainage channel in the center of the two gutters to 2.5 to 5.0 times the slot width is appropriate.
