Abstract
This work aimed to converge studies of aerodynamics with vehicle dynamics and utilize numerical analysis in CFD (Computational Fluid Dynamics) to investigate the influence of the rear wing on high-performance cars, specifically Formula One cars. The studies conducted for braking and sliding analysis were based on an airfoil profile, namely the NACA 2412, as well as the Drag Reduction System (DRS) mechanism for angle variations ranging from 20º to 0º. Before generating results, mesh refinement was necessary to converge the data for lift coefficient, drag coefficient, and pitch moment. The adopted vehicle dynamics model for the study was the quasi-static model, and flow analysis was conducted to investigate the influence of the rear wing on the vehicle body. The braking situation occurred on a hypothetical straight, flat track without crosswinds, and the sliding situation occurred on the Monza track at the La Parabolica curve, also considered flat and without crosswinds. The software used for the analysis included SolidWorks™ for generating CADs of the rear wings, ANSYS FLUENT™ for mesh generation and obtaining aerodynamic load data, and finally Python for importing the data into Excel, where vehicle dynamics formulas for tire reactions during braking and sliding were implemented.
