ABSTRACT
The objective of the present test case is to analyze the field resulting from a 3D shock wave /boundary layer interaction occurring in a 3D channel with a swept bump. In this case, the interactions taking place with the boundary layers of the four walls can lead to the formation of several separations which are at the origin of vortical structures cause of intense secondary flows. Experiments executed at Onera by Délery team provide a thorough description of the flow field and detailed experimental data are available [1]. Reference computations with RANS/2 eq. turbulence models have been performed [2].
The target quantities of interest are the static pressure distribution on the walls, the turbulent kinetic energy profiles and the mean stream-wise velocity profiles in longitudinal planes.
