Aerodynamic Design of Savonius Wind Rotors

This paper summarizes the aerodynamic theory,advantages and disadvantages of the Savonius wind rotor.The emphasis is laid on the parameters of outline,which affect the aerodynamic performance of the Savonius wind rotor.The optimum parameters are determined on the basis of present researches.The outline of the 300 W Savonius wind rotor is designed on the basis of the optimum parameters,and the results can provide the theoretical guide to the design of the wind turbine.
