AbstractThe present work deals with the turbulent flow simulation of an airfoil with a generic flap. The purpose of this simulation is to provide the time history of the pressure field on the wing and on the flap for noise prediction. The configuration and the flow conditions were defined in the FP7 VALIANT project. Within this framework measurements were performed in Ecole Central de Lyon, to which the present simulation is compared. In order to be able to reproduce the measurements with numerical simulation, the experimental velocity profiles on the middle of the wing were used as inlet boundary conditions. In this work three different inlets were used and the resulting flow fields were compared.
