Savonius Wind Turbine: Principles, Power Equation, and Design Optimization
Introduction The Savonius wind turbine is a vertical-axis wind turbine (VAWT) that operates on the principle of drag difference rather than aerodynamic lift. Invented by Finnish engineer Sigurd J. Savonius, it is widely known for its simplicity, self-starting capability, and ability to operate in low and turbulent wind conditions. While it is not…
