Abstract

The transition to renewable energy sources is crucial to addressing global climate challenges, with wind energy emerging as a viable and cost-effective solution. Vertical-axis wind turbines (VAWTs) offer advantages over traditional horizontal-axis wind turbines (HAWTs), particularly in their ability to harness wind from multiple directions and operate efficiently at lower heights. This study focuses on the design and aerodynamic analysis of a hybrid Savonius-Darrieus wind turbine, combining the self-starting capability of the Savonius rotor with the high-efficiency aerodynamic performance of the Darrieus rotor. It used computational Fluid Dynamics (CFD) simulations conducted in ANSYS Fluent to analyze the aerodynamic performance of various design modifications at stationary conditions. Three modifications were applied to the Savonius rotor to optimize its operational efficiency, including the extension of blade ends, alterations in blade separation, and the introduction of blade twist. Results indicate a 12.6% increase in torque and Cp increase at 11.74 % for the modified models compared to the original configuration, particularly at low wind speeds (1-10 m/s). For the Darrieus turbine, aerodynamic profile selection and optimization were performed using QBLADE, focusing on various National Advisory Committee for Aeronautics (NACA) airfoils, blade chord width, and tip speed ratio (TSR). The selected NACA 4412 profile demonstrated superior lift-to-drag ratio characteristics, making it ideal for integration into the hybrid system. Simulation results provide insights into velocity distributions, pressure contours, and wake formations, highlighting areas for further optimization. The hybrid turbine design shows promise in improving energy capture efficiency while addressing the self-starting limitations of conventional Darrieus rotors. This study concludes that the hybrid Savonius-Darrieus turbine offers a balanced approach to wind energy generation, leveraging the complementary strengths of both rotor types.
