Improving the Performance of a Savonius Rotor Through Blade Shape Modification

The Savonius rotor is a specific type of wind turbine with a vertical axis of rotation. known for its high potential in harnessing wind energy. Despite its promising capabilities, the performance of Savonius rotors is frequently limited by low efficiency. This study explores the enhancement of the efficiency of a Savonius wind rotor by employing a novel blade shape. The results obtained from the proposed numerical model, developed using ANSYS Fluent, are compared with experimental data available in the literature. Special attention is given to highlighting the moment and power coefficients, as well as the local aerodynamic characteristics of the proposed rotor. The findings demonstrate that modifying the blade shape is crucial for enhancing the power output of the Savonius turbine. The results reveal a notable enhancement in the rotor's aerodynamic efficiency, offering a solution for optimizing wind energy capture.
