Abstract

In the present paper the comparison between experiments and numerical simulations for a generic Scram- jet configuration are been presented. The experiments have been conducted for a Mach 7 condition at the hypersonic blow down wind tunnel H2K at the German Aerospace Center (DLR) in Cologne. The cor- responding numerical simulations have been performed using two different numerical solvers. During the experiments, air was injected through central strut and wall-ramp injectors to simulate a combustion back- pressure. In order to generate a database for a comparison between numerical and experimental data, wall pressures were measured along the bottom and top side walls, Pitot pressure at the exit of the combustor, and heat ux on the sidewalls. The reasonable good agreement between the experiments and the numerical solutions show the feasibility of the numerical tools to predict complex ow structures in high-speed ows. Furthermore, an extrapolation of the numerical and experimental data to real ight conditions at an altitude of 30km was undertaken and the feasibility of the proposed Scramjet configuration is been shown.
