英文摘要	In order to forecast the rotating speed of the hydraulic energy recovery turbine, Single centrifugal pump and single centrifugal pump with guide vane in reverse operation were adopted as turbines. 3D models were founded by pro/E software for turbines, Then the models were meshed by gambit and Simulated by fluent6.3 software. It was shown that before the best efficiency points, The higher the rotating speed, the lower the efficiency of turbine. but after the best efficiency points, the efficiency of turbine increased with the rise of rotating speed. with the rise of rotating speed,the pressure in runner inlet was added, the amplitude of pressure pulse was added. the pressure distribution in runner inlet was more even of model B than that of model A. With a guide vane,The steady scope of rotating speed in hydraulic energy recovery turbine was diminished, and the Controllability of rotating speed in hydraulic energy recovery turbines can be improved by guide vane. Some theories were offered for hydraulic energy recovery turbine researches.
