abstract

This study deals with the L arge E ddy S imulation of a 3D unsteady shock wave/boundary layer interaction, in sight of turbomachinery applications. The simulation of a compressible flow through a 3D channel (ONERA) has been performed in LES, with a third order WENO scheme (Jiang, Shu, 1996) and the mixed scale model (Tenaud, Ta Phuoc, 1996). The flow has already been studied experimentally at ONERA (Cahen, 1995), and numerically with RANS modeling (Gerolymos, Vallet, 1997). The unsteady results obtained by LES within and downstream of the 3D interaction are presented and analyzed. The mean velocity profiles in the interaction zone, are then compared to both experiments and statistical numerical results.
