The present work discusses the predictive capabilities of the PANS model of turbulence (Partially-Averaged Navier Stokes; Basara et al. [4], representing a hybrid RANS/LES (Reynolds-Averaged Navier-Stokes/Large Eddy Simulation) modelling scheme, by means of simulating the flow past different car configurations including also overtaking maneuver cases. The unresolved residual turbulence is modelled by an appropriately adapted RANS-ζ-f formulation (proposed originally by Hanjalic et al. [9]). The investigated car configurations include a 40% down-scaled BMW model [17] as well as the so-called “DrivAer” car model [10]. As outcome of an intensive computational campaign by employing the PANS-ζ-f model formulation detailed mean flow and turbulence fields are obtained illustrating the model’s predictive capabilities in capturing unsteady features and corresponding time-averaged flow properties in a wide range of car configurations considered.
