Innovative Design and Aerodynamic Performance Investigation of Converged-Divergent Ducted Horizontal Axis Wind Turbine on a Car Roof through Computational Fluid Dynamics Approach

This work presents a novel mechanism for harnessing wind energy to generate electricity for electric vehicles (EVs) in motion. A horizontal axis wind turbine (HAWT) is strategically placed on the rooftop of the vehicle to maximize wind energy capture and eliminate the need for traditional charging stations. The design of the HAWT, created using SolidWorks, takes specific factors into account. Computational fluid dynamics simulations are performed using ANSYS Workbench 17.2 to analyse the optimal mounting location by assessing pressure differences caused by air velocity over the car's external surface. Key parameters, including drag and directional forces, are evaluated to ensure that the impact on vehicle speed is minimal. Both numerical and experimental findings demonstrate enhanced aerodynamic performance in diffusers equipped with ducted HAWT compared to conventional energy concepts. This innovative approach offers a sustainable solution for on-the-go EV charging while minimizing aerodynamic drag compared to traditional vehicle models. The proposed wind-powered Convergent-Divergent duct aims to harness kinetic energy from the vehicle's motion to generate electricity. This initiative aligns with the global trend toward sustainable energy practices and addresses specific challenges within India's energy landscape. The work strives to provide an innovative and practical solution that seamlessly integrates into existing transportation systems, offering a clean and renewable energy source. By doing so, it aims to reduce the environmental impact associated with conventional power generation methods, marking a significant step toward a more sustainable and eco-friendly energy future.
