摘　　要：基于微可压缩流体理论建立了水力过渡过程的控制方程组,获得了水电站引水系统水力过渡过程计算的一维和二维模型,并应用于计算和模拟水电站引水系统过渡过程、调压室水位波动、流速场与压力场变化过程。结果表明,计算与试验结果基本吻合,误差小于3%,为调压室的结构设计提供了依据。Based on the weakly compressible fluid,governing equations of the hydraulic transient process are established.One-dimensional and two-dimensional computational models of hydraulic transient process for water diversion system of hydropower plant are developed respectively.And then it is used to simulate the transient process of water diversion system,water level fluctuation,pressure distribution and velocity field in surge chamber.The results show that the computational results coincide with the experimental results and the error is less than 3%.Therefore,it can provide scientific basis for design of surge chamber.
