Aerodynamic Analysis of Small-Scale Turbines with Complex 3D Blade Shape

The paper presents a comprehensive aerodynamic analysis of toroidal blade turbines, proposing them as a novel approach to enhance efficiency in the conversion of airflow kinetic energy.The unique toroidal blade geometry allows for reduced vortex-induced losses and improved aerodynamic performance relative to conventional blade configuration.The study encompasses crucial performance parameters, including the airflow velocity at the outlet of the aerodynamic channel, rotational speed of the turbine model, electrical current and voltage output, the electrical power produced by the generator, and the power coefficient.Explored are strategies for optimizing structure design to minimize losses and maximize the power coefficient.The findings reveal that toroidal blade designs can significantly increase the effectiveness of low-power turbines, establishing them as a promising alternative for renewable energy applications in both urban and rural environments.
