Feasibility of Hybrid RANS-LES Modeling of Shock/Boundary-Layer Interaction in a Duct
Paper i proceeding, 2012

A shock induced boundary-layer separation (SBLI) occurring in a duct at $M=1.4$ has been analyzed using hybrid RANS-LES methods. The shock wave interacts with the turbulent wall boundary layers and triggers flow separation in the duct corners. The main purpose of the present work is to highlight the difficulties in modeling SBLI, particularly, when hybrid RANS-LES models are used. Results computed using different turbulence models are presented and discussed in comparison with available experimental data. Based on a number of simulations, some issues are addressed and some critical remarks are provided for potential improvements using turbulence-resolving modeling approaches in future work.
