RTO WG 10 - Test cases for CFD validation of hypersonic flight

Abstract

The NATO Research Technology Organization (RTO) Advanced Vehicle Technology (AVT) panel established Working Group 10 (WG 10) "Technologies for Propelled Hypersonic Flight" in 1998. The Terms of Reference included three Subgroups: (1) aerospike plug nozzle, (2) RAM/SCRAM jet configurations, and (3) Computational Fluid Dynamics (CFD) validation. An overview of Subgroup 3 (SG 3) is presented in this paper. The SG 3 participants defined six topical areas for which validation of CFD methodologies was deemed essential for effective analysis and design of propelled hypersonic vehicles. The topics are boundary layer instability and transition, real gas flows, laminar hypersonic viscous-inviscid interactions, shock-shock interactions, shock wave-turbulent boundary layer interaction, and base flows with and without plume interaction. A set of experiments were selected by Subgroup 3 participants for each topic and computations were solicited. The experiments are described in this paper. The results of the computations are presented in separate papers.
