Abstract
Experimental investigations were carried out to study the external overlap ratios effect on the performance of a vertical axis wind rotor of the Savonius type. For thus, an open wind tunnel has been designed and realized in Laboratory of Electro-Mechanic Systems at National School of Engineers of Sfax. This involved also the instrumentation and the necessary equipment for the global characterization of the Savonius wind rotor. Particularly, this research required the setting up of four mounting characterized by different external overlap ratios. The overall performance evaluation of the rotor has been based on the power and dynamic torque coefficients in function of the air velocity speed measured in the test vein of the wind tunnel.
