Validation of CFD for racing car analysis and design

This paper demonstrates the validation of a CFD code for external and internal automotive flows. Specifically, it illustrates the ability of rapid multi-block grid regeneration for topologically similar configurations, and the modelling of the effect of vortex generators without the addition of their physical geometry to the solution domain. This flow control technology is then applied to the air inlet and duct system of a generic-racing car to demonstrate how the performance may be modified.
