The Savonius wind turbine is a type of vertical axis wind turbine capable of operating at low wind speeds; however, it still has limitations in terms of aerodynamic performance and power output. This study aims to analyze the effect of guide vanes on the performance of a magnetic gear-based Savonius wind turbine in terms of rotational speed (RPM), output power, and system efficiency. An experim…
Urban wind characteristics, characterized by low velocity and high turbulence, limit conventional wind turbine performance. The Savonius Vertical Axis Wind Turbine is a suitable alternative, but its efficiency is hindered by negative torque on the returning blade. This study aims to optimize a two-bladed Savonius turbine by integrating a fixed 8-blade guide vane system with tilt angles of 30°,…
