A Computational Fluid Dynamics (CFD) study has been conducted to analyze the efficiency of the newly designed drag-driven Torque Wind Turbine (TWT). Specific objectives of this study are the analysis of the flow field around one blade of the turbine fixed in a static position, and the generation of the power and torque coefficient curves for a single rotating blade. The commercial software Ansys Fluent was used to perform the simulations adopting the SST k-ω turbulence model. A single blade of the turbine offers a maximum power coeffi- cient around 0.065 at a tip speed ratio ranging from 0.45 to 0.55 depending on the wind speed.
