以新疆小石峡水电站为例,采用FLUENT软件、RNGk-ε紊流模型及VOF方法相结合处理了自由水面,并对溢洪道的流场进行了三维数值模拟,得到了优化溢洪道在设计流量1 856.2 m3/s时的泄流流态,并将消力池段自由水面线、底板压强、断面流速与模型试验结果进行了比较,结果表明数值模拟结果与模型试验结果吻合较好。
以新疆小石峽水電站為例,採用FLUENT軟件、RNGk-ε紊流模型及VOF方法相結閤處理瞭自由水麵,併對溢洪道的流場進行瞭三維數值模擬,得到瞭優化溢洪道在設計流量1 856.2 m3/s時的洩流流態,併將消力池段自由水麵線、底闆壓彊、斷麵流速與模型試驗結果進行瞭比較,結果錶明數值模擬結果與模型試驗結果吻閤較好。

Combined with the FLUENT software,RNG k-ε turbulent model and VOF method,the free water surface is handled,and 3D numerical simulation is implemented for the flow model on the spillway of Xiaoshixia Hydropower Station.Then the discharge flow patter in the design flow 1 856.2 m3/s of the optimized spillway is gotten,and the free water surface,pressure distribution and velocity are obtained.It is showed through comparison that the numerical simulation results are basically consistent with the test data of physical model.
