AB  - 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.
