采用FLUENT软件对长短叶片混流式水轮机HLA351转轮在额定工况下进行了三维定常数值模拟,较好地预测了转轮内部流场详细情况.计算结果表明,增减短叶片,转轮内部流态出现了较大的变化,其中长短叶片结合式转轮流态最好,水力性能最优,长叶片转轮次之,短叶片转轮较差.
採用FLUENT軟件對長短葉片混流式水輪機HLA351轉輪在額定工況下進行瞭三維定常數值模擬,較好地預測瞭轉輪內部流場詳細情況.計算結果錶明,增減短葉片,轉輪內部流態齣現瞭較大的變化,其中長短葉片結閤式轉輪流態最好,水力性能最優,長葉片轉輪次之,短葉片轉輪較差.

Numerical simulation of three-dimensional turbulent flow through three Francis turbine runners for which type of blades is different is conducted on the basis of Reynolds equations closed by Standard k-e turbulent model with general coordinates. The model of calculation is HLA351. The results show that the detail of flow field in Francis turbine runner can be well predicted. In the same circumstances, hydraulic performance of the runner with long and short blades is better than conventional runner. It can be concluded that the results are able to provide an important guideline for the hydraulic design of Francis turbine or its optimization.
