摘要

Governing bodies of professional motor races impose a great deal of restrictions on many aspects of the car. Success is therefore highly dependent upon the external performance of the vehicle i.e. how to generate the maximum amount of downforce with the smallest drag penalty possible. The external aerodynamics exhibit many complex flow features, including vortex shedding and strong separation, amongst others. Because of the time scales involved in this industry, RANS turbulence modelling is the only feasible approach. In the present contribution, a number of schemes are tested over a range of homogeneous flow cases, covering a variety of flows with shear, normal straining, rotation and unsteadiness, highlighting the weaknesses, strengths and potential strengths of the different model formulations.
