Abstract

This work describes the application of a cell-centered unstructured finite volume method with finite-rate chemistry model to hypersonic flows. The complex internal viscous flow in the HyShot-II Scramjet model is studied. Two dimensional CFD analyses considering air dissociation are presented on the complete geometry of the HyShot-II scramjet and separately on the combustion chamber at fuel-off conditions as a precursor to the future studies of three dimensional simulations, fuel-on combustion flows and designs of different scramjet models. The simulated pressure distribution in the combustor chamber at free stream flow of Mach 7.4 and altitude of 27 km is compared with the experimental results of a full-scale model of the HyShot II vehicle presented by Schramm et al1 conducted at the High Enthalpy Shock Tunnel (HEG), German Aerospace Center (DLR). Good agreement is observed between the wind tunnel test and CFD results.
