A Curtain Design on Optimizing Configuration of Savonius Rotor
This paper mainly studies the configuration of Savonius rotor on the basis of the output power P= 100 W, and the best parameters of the number of blade.aspect ratio and overlap ratio have been found. On this basis, a curtain arrangement has been designed, and the optimum configuration of Savonius rotor has been put forward in this study. Then, the multifarious blades of Savonius wind rotor without or with curtain have been placed in the wind tunnel and simulated by the fluid engineer simulation software Fluent with the finite volume method. And these conclusion combined with the calculation of the aerodynamic performance parameters of the optimum configuration of Savonius rotor verify the design on Savonius rotor with long curtain in the possession of the best dynamic performance. This optimum Savonius rotor in the present study has achieved the improve- ment of the operating efficiency.
