Abstract: In the present study, a new model of Savonius wind turbine has been designed to increase the low performance of the Savonius wind rotor, a type of vertical-axis wind rotor, and the effect of wind speed on the static rotor performance has been analyzed numerically using solid-work flow simulation (SWFS). SWFS is based on the Reynolds Averaged Navier-Stokes (RANS) equations with the standard k-e turbulence model. These equations were solved by a finite volume discretization method. Further, the effects of rotor geometries and end plate on static torque are also discussed. In order to clarify the new designed of the rotor, static torque was measured with various blade sizes and end plate shape. From the study, found that the use of both upper and lower end plats significantly increase the torque by 40% compared with no end plates. Additionally, it was also observed that the torque of rotors increases proportionally to blade size and end plate shapes. Moreover, the results showed that model 2 has produced more torque compared to other models.
