Test case description
- The aim of this chapter is to set up, run and evaluate a simulation of the external aerodynamics of a car.
- There are two cases to run. The first one deals with the incompressible air flow around a car body. The second one has a very similar setup but a slightly different geometry: the flow around a car body with an engine compartment is simulated. This modification shows that even such a simple change can bring more realistic results.
- The engine’s heat exchanger in the engine compartment will be modeled as a porous zone.
- In both presented cases we are going to use the inlet boundary condition for velocity with a parabolic profile in the boundary layer.
- Test case parameters:
Car dimensions are circa
Kinematic air viscosity:
