【摘要】 结合万家寨引黄工程输水工程,对压力管道出口高速水流的消能问题进行了试验研究。在无控制自由泄放的情况下,试验确定了多喷孔射流消能竖管周边的开孔大小, 布置方式及建筑物体形尺寸,使各级流量下出口能量得到合理的消除,并使水流平稳进入下游衔接渠道。所得结论与实际运行情况相符。更多还原

【Abstract】 Based on the Yellow River Diversion Project (YRDP), an experimental study on the dissipation measures of pressure pipe outlet is presented in this paper..Under the condition of freedom discharge without any controls, the size and the disposal mode of the hole opened on the erect pipe for dissipation have been confirmed. Making the water flow into the downstream channel smoothly. The results obtained in this paper are in agreement with the operation in fact.更多还原
