  6. 5. Design Optimization of Savonius Wind Turbine using CFD Simulations

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Vatsalkumar Manavar; [2023]
    Keywords : Savonius wind turbine; Computational fluid dynamics; Vertical axis wind turbine; Overlap ratio; Distance between blades; Power coefficient;

    Abstract : This thesis is based on a simulation of the Savonius wind turbine. The Savoniusturbine is a simple vertical axis device, which has half cylindrical blades attached to the main shaft opposite to each other which creates the drag force from incoming wind and generates mechanical torque which drives the generator for electricity generation.
