After brief recalls of the theoretical foundations of incompressible fluid dynamics, the mechanisms for generating the aerodynamic forces acting on vehicles are described, in particular both for passenger and high-performance vehicles. The experimental tests, on the road and in the wind tunnel, and the numerical simulations for the aerodynamic study of a vehicle, or components, are then described. In particular, the schedule can be summarized with:
1. Introduction to the aerodynamics of a vehicle
2. Incompressible fluid dynamics in a nutshell (governing equations, boundary layer theory, drag and aerodynamic downforce)
3. Influence of aerodynamics on the performance of a vehicle
4. Aerodynamics of a vehicle
5. Aerodynamics of high-performance vehicles (ground effect, Venturi effect and aerodynamics of additional components)
6. Experimental aerodynamics, road and wind tunnel tests
7. Numerical aerodynamics (RANS, LES equations and RANS-LES hybrid methods)
8. Overview of the rear wings for high-performance vehicle
During the course exercises are carried out with the OpenFOAM opensource toolbox, in particular the study of the aerodynamic performance of:
1. Ahmed body
2. DrivAer car
3. Perrinn F1 project
