Pagination or Media Count:
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.
