Aerodynamic characteristics of Ahmed body with inverted airfoil Eppler 423 and Gurney flap on fastback car

The installation of aerodynamic devices, such as rear wings with the application of a Gurney flap, is very important to improve the performance of vehicles and can generate downforce and reduce slip when a car turns and brakes. The goal of this study was to determine the aerodynamic characteristics...
