本文应用雷诺方程及ｋ－ε模型对水电站机组冷却供水的调节和非调节式液体射流泵流场进行了数值模拟，并导出了调节式液体射流泵基本方程及其简化计算公式，通过试验资料进行了初步验证．
In this paper, the Reynolds equation and the k-ε model are used to simulate the cooling water supply of the hydropower station and the flow field of the unregulated liquid jet pump. The basic equations of the regulated liquid jet pump and their simplified formulas are derived. The experimental data A preliminary verification.
