Abstract

The objective of this study is to help design and model a new Savonius-style wind turbine that will have better performance than conventional Savonius wind turbines in terms of power. The geometrical parameters of the new Savonius-style were optimized to generate an optimum performance. An experimental investigation along with a numerical study using "Solid Works Flow Simulation" (SWFS) has been carried out to accomplish the objective. The static torque values of the rotor have been measured by experiments and calculated by numerical analysis and finally, they have been compared at different rotor positions ranging from 0°-360°. Experiments were conducted in front of a low-speed subsonic wind tunnel to determine the static and dynamic torques, the mechanical power as well as electrical power. In both studies, the new Savonius-style wind turbine was tested at various wind speeds ranging from 3-12 msec. Based on the experimental results, the newly developed Savonius-style resulted in a noticeable improvement in the power compared to that of the conventional Savonius rotors. Moreover, the results show that the long overlap significantly increases the power: by 40% compared with short overlap.
