Scrutinising flow field pattern around thick cambered trailing edges: experiments and computations

A detailed experimental study has been launched at ONERA/DMAE, aiming at th e description of the flow pattern in the vicinity of thick cambered trailin g edges. LDV and pressure measurements have provided a very detailed databa se which has been considered, for validation of computational tools. Thus, several one- and two-equation turbulence models, implemented in the Reynold s-averaged Navier-Stokes (RANS) solver developed at ONERA, have been applie d to the experimental configurations. Typical features are carefully discus sed with emphasis set on both pressure distributions (prediction of correct rear loading) and near-wake surveys (capture of the topological vortex-typ e structure).
