摘　　要：库什塔依水电站导流兼泄洪洞出口消能根据地形条件采用底流消能工消能。通过采用RNGk-ε模型模拟湍流，利用VOF法追踪自由水面，对通过物理模型试验最终确定的消力池及其辅助消能工体形进行三维流场数值模拟计算，并将物理模型试验结果与数值模拟计算结果进行对比，分析表明两者吻合较好，其结果可以为底流消能体形优化设计提供依据。The hydraulics jump is used for the outlet energy dissipation of diversion ＆ spillway tunnel in Kushitayi I-Iydropower Station according to terrain conditions. The RNG k -ε turbulence model and VOF Method are employed to numerically simulate the 3-D flow field of stilling pool which is determined by physical model tests. The comparison of physical model test and numerical simulation shows that the difference is not apparent. The numerical simulation can provide reference for the shape design and optimization of energy dissipator.
