| Abstract: | In order to improve the efficiency of the Blade Position-Variable Hydraulic Turbine, a three-piece energy-gathered and diversion mechanism is proposed, combined with motion law of hydraulic turbine. By means of the numerical simulation method, the accelerating effect of different parameters of NACA air-foil is studied, then the specific structure of energy-gathered and diversion mechanism is determined. A kind of energy-gathered and diversion mechanism with excellent hydraulic performance is obtained through changing several important parameters. |
