RTO WG 10 - CFD validation for shock wave turbulent boundary layer interactions

Abstract

Abstract : NATO RTO Working Group 10 was established in December 1998 to examine the technologies of plug nozzles, scramjet propulsion and Computational Fluid Dynamics (CFD) for design of propelled hypersonic vehicles. The CFD subgroup evaluated six topics: boundary layer transition and instability, real gas flow, laminar viscous-inviscid interactions, shock-shock interactions, shock wave turbulent boundary layer interaction (SWTGBLI) and base flows with and without plume interaction. This paper presents a summary of the evaluation of shock wave turbulent boundary layer interactions. Five configurations were considered: 2-D compression corner, 2-D expansion-compression corner, 2-D shock impingement, 3-D single fin and 3-D double fin. Recent Direct Numerical Simulations (DNS), Large Eddy Simulations (LES) and Reynolds-averaged Navier-Stokes (RANS) simulations are compared with experiment. The capabilities and limitations are described, and future research needs identified.
