Aerodynamic Energy Harvesting for Electric Vehicles

This study aims to achieve a method for harvesting energy from an automotive vehicle to improve its performance. A novel idea is discussed where the aerodynamic drag is used to harvest the energy from a car. This paper encloses virtual experiments and trials to use the vehicle's frontal area to channel the airflow at high speeds into a duct and generate power using a turbine generator system inside the duct. Numerous trials and simulations are done to optimize the experiment, and this paper gives a great insight into the possibility of harvesting energy utilizing the drag force experienced while driving a car at a considerable speed. The paper discusses the methods taken to design the duct inside the frontal area of the vehicle more efficient and robust in geometry, and also considers the shape of the frontal area so that it does not hamper the airflow reaching the duct, which in turn rotates the turbine forth the duct to generate power. All aspects of this paper are minutely taken care of, and the calculations are based on various assumptions mentioned in the paper itself. This paper focuses on a better way to harvest energy and is expected to be helpful in future studies and help the upcoming industry of electric cars.
