Experimental Study of the Internal Overlap Ratios Effect on the Performance of the Savonius Wind Rotor

Abstract

In this paper, experimental investigations are carried out to study the internal overlap ratios effect on the performance of a Savonius wind rotor at different Reynolds numbers. To do this, 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 equipments for the global characterization of the vertical axis wind turbines. Particularly, this research required the setting up of four mounting characterized by the internal overlap ratios equal to rpi=0, rpi=0.1, rpi=0.2 and rpi=0.3. The overall performance evaluation of the rotor has been based on the power and dynamic torque coefficients
