On the Wall-Modeled LES use of ZDES in compressible flows

Résumé

The present study is devoted to the use of the Zonal Detached Eddy Simulation (mode 3) hybrid RANS/LES method as a Wall-Modeled Large Eddy Simulation technique in com-pressible flows. The first section is devoted to a supersonic turbulent boundary layer test case, showing that the performance of ZDES mode 3 is satisfying in supersonic conditions, validating this WMLES method previously analyzed at low Mach numbers. Then the interaction of this boundary layer with an oblique shock wave is considered, with a promising qualitative agreement with experimental data and enhanced predictions compared with RANS. Finally, a new strategy by Deck et al. [1] for a low-noise resolved turbulence generation is presented, which is expected to be instrumental for the next use of ZDES mode 3 in aeroacoustic studies.
