摘要
爆破膜在现代水电站建设中,特别是中小型水电站中有广泛的应用.但当爆破膜爆破后,高速水流对尾水渠产生巨大的冲刷,如何有效解决高速水流消能成为水电站设计中的关键问题.本文通过加设消能池,使高速水流通过淹没射流的方法安全泄流消能,并通过数值模拟的方法证明其有效性.
Blasting membrane in the construction of modern hydropower plant , especially in the small and medium-sized hydropower station has a wide range of applications .But when blasting membrane after blasting , an enormous erosion of tailrace high speed water flow , how to effectively solve the high -speed water flow energy dissipation has become key problems in design of the hydropower station .This article by adding energy dissipation pool, make the high speed water security by using the method of submerged jet discharge energy dissipation , and through the numerical simulation method to prove its validity .
