摘要
基于环形叶栅理论建立转轮叶片三维模型。采用FLUENT软件对转轮叶片进行了三维定常湍流计算,数值模拟了转轮内部三维湍流流场,得到了叶片表面压力云图、速度矢量图和叶片进出口边附近压力分布图,并估算出水轮机水力效率。结果表明采用环形叶栅理论建立的贯流式水轮机叶片具有可行性。
The three-dimensional model based on the theory of runner blade annular cascade.The runner blade of the three-dimensional steady turbulent flow is simulated by using FLUENT software. It is near the pressure distribution of import and export of blade surface pres- sure contours velocity vector and the blade and the estimation of the water turbine hydraulic efficiency. The results show that the establish- ment of the annular cascade theory of cross flow with the feasibility of turbine blade.
