Simulation study demonstrates up to a 1.9-fold increase in wind velocity through structural optimization, suggesting improved closed-type wind turbine efficiency.
This paper presents a comprehensive approach to studying the influence of low-power wind turbine’s structural elements design, such as confuser, diffuser, and cone, on its efficiency. The turbine geometry was created in the ANSYS DesignModeler environment and analyzed using ANSYS Fluent 2024 R1. The streamline distributions of velocity and pressure were examined for various configurations of the confuser, diffuser, and cone. Based on the simulation results, the optimal angles of attack for these components were identified, providing practical design recommendations for closed-type wind turbines. The proposed configuration has the potential to increase the wind velocity by up to 1.9 times at optimal angles, demonstrating the effectiveness of an integrated design approach in enhancing turbine efficiency.
