Wind energy generated from the wake of moving cars has a large energy potential that\nhas not yet been utilized. In this study, a vertical axis wind turbine (VAWT) was used to recover\nenergy from the wakes of moving cars. The turbine was designed to be planted by the side of the car\nlane and driven by the wake produced by the car. Transient computational fluid dynamics (CFD)\nsimulations were performed to evaluate the performance of the VAWT. The influence of two main\nfactors on the performance of the VAWT, the velocity of the car and the gap between the car and\nthe rotor, were studied. The simulations confirmed the feasibility of this plan, and in the tested\ncases, the VAWT was able to generate a maximum energy output of 100.49 J from the wake of a car.\nThe results also showed that the performance of the VAWT decreased with the velocity of the car,\nand the increased gap between the car and the VAWT.
