Design, Construction, and Testing of a Savonius Wind Turbine

Abstract

This project encompasses the comprehensive design, construction, and rigorous testing of a pioneering 640W Savonius wind turbine, characterized by a swept area of 4.9087m², boasting numerous advantages, including a straightforward and simplified construction process facilitating easier assembly and maintenance, high startup speeds enabling efficient energy harnessing, and the unique ability to capture wind from any direction, thereby enhancing its adaptability and versatility in diverse environmental settings. Additionally, the turbine operates at a remarkably low noise level and maintains a reduced angular velocity, minimizing wear and tear on moving parts, thus extending the lifespan of the machine and achieving a maximum averaged power coefficient typically ranging from 0.05 to 0.30, depending on the specific operational conditions and geometric parameters employed. Notably, the incorporation of stators has been shown to optimize performance at the tip speed ratio corresponding to the maximum averaged power coefficient, underscoring the significant potential for enhancing energy output. Ultimately, this project highlights the importance of innovative wind turbine designs like the Savonius in advancing renewable energy technologies and contributing to sustainable energy solutions, while also providing a foundation for future developments in wind energy technology and emphasizing the need for continued exploration of alternative designs that can meet the growing demand for clean energy.
