Experimental study on a self-adapting Darrieus—Savonius wind machine

Abstract In the present paper a study of the starting torque and power coefficient of the Darrieus and Savonius machines have been realized. The results obtained were used to design a Darrieus-Savonius combined machine which is also fully analysed. Finally, a new design of the Darrieus-Savonius combined rotor is proposed and analysed.
