摘　　要：盖板竖井式进 出水口是抽水蓄能电站采用的形式之一 ,出流工况的水力学问题是其难点问题。本文利用三维k ε紊流数学模型 ,针对西龙池抽水蓄能电站上水库盖板竖井式进 出水口 ,研究了抽水工况出流时竖井扩散段、孔口附近的流动特性 ,探讨孔口底板附近反向流速的成因。Vertical pipe intake with plate is one type of pumped storage plant’s intakes,the hydraulic characteristics in the pumping condition is not clear yet.The hydraulic characteristics in the pumping condition of the vertical pipe intake with plate in the upper reservoir of Xilongchi pumped storage plant are investigated by 3?D k?ε turbulent model.The flow in the vertical pipe outlet in the pumping condition are simulated,and the genesis of reverse flow at the bottom of outlet is investigated.The numerical calculated results are compared and verified with the experimental results.
