ABSTRACT
The chapter aims to examine the flow of air beside the rear wing of a Formula One (F1) car with variable velocities using Computational Fluid Dynamics (CFD) simulation. The investigation was performed using a 2-D model consisting of a flap-wing along with the main plane, combined to form the rear wing assembly. Both the airfoils are positioned inside a flow domain of 2.5 m long and 1.5 m in height. The parametric study of the effect of the angle of attack of the rear wing profile on drag and lift coefficients has been performed. The numerical simulations were executed by using CFD solver ANSYS FLUENT using the k-ꙍ-SST turbulence closure. The wind velocity over the wing was varied from 22 m/s to 104 m/s, which correspondes to the car speed achieved during major segments of any F1 race. This study uses NACA 2415 and NACA 2412 for the flapping wing and the main plane, respectively. There were a total of 16 angles considered with 3 different velocities. A grid independence test and the best suited CFD Model were selected based on previous research done on similar aerofoil to ensure that the results obtained are adequate. The objective of this learning is to probe the aerodynamic conduct of the flow of air over the rear wing assembly for different angles of attack (AOA) influencing the flow over it.
