Savonius wind turbine is a vertical axis wind turbine driven by drag force and has been spread gradually in urban areas. In the present study, we quantify the performance of a Savonius wind turbine in a flow with high isotropic turbulence over 20% produced in a far field of an open-jet type wind tunnel. The performance of the Savonius wind turbine estimated from measured rotational speed using a tachometer shows that the idling tip speed ratio increases in the high turbulent flow in comparison with the case in the flow inside potential core. The result implies that Savonius turbine has a function to capture the turbulence as an additional source of power.
