进/出水口是抽水蓄能电站输水系统的重要组成部分,其水力性能直接关系到抽水蓄能电站的运行和经济效益。利用CFD软件,对某抽水蓄能电站上库四孔侧式进/出水口进行数值模拟计算,模拟其在不同库水位、不同运行工况下的水力特性,包括水头损失、通道中流量分配及流速分布情况。结果表明,该方法得到的数值模拟结果均符合客观规律,与物理模型试验结果具有较好的一致性和精度,可实现对抽水蓄能电站上库侧式进/出水口水力特性的预测,对指导实际工程建设具有一定意义。
The inlet / outlet is an important part of the water delivery system of a pumped storage power station. Its hydraulic performance is directly related to the operation and economic benefits of the pumped storage power station. The CFD software is used to simulate the four-side inlet / outlet of a pumped storage power plant, and simulate the hydraulic characteristics under different operating conditions, including head loss, flow distribution in the channel and Flow rate distribution. The results show that the numerical simulation results obtained by this method are in line with the objective laws and have good consistency and accuracy with the results of the physical model test, which can predict the hydraulic characteristics of the side inlet / outlet of the upper reservoir of the pumped storage power station. To guide the actual construction has a certain significance.
