RECENT Experiences of PANS predictions in vehicle aerodynamics
Paper in proceedings, 2016

This paper presents recent applications of the Partially-averaged Navier-Stokes equations for external vehicle flows. The flow predictions range from simplified ground vehicle flow, flow around a freight train locomotive to the investigation of a simplified truck at yaw, and active flow control. The new predictions show good agreement with the experimental observations. The results of the PANS simulations are used to study the differences between the quasi-steady and dynamic change of the yaw for the flow around a simplified truck cabin. Furthermore, active flow control was implemented with the aim to suppress the separations around the front A pillars of a simplified truck using PANS.
