Abstract

Two-dimensional temperature measurements of the interaction between a sonic H2 jet injected into a hypersonic air-crossflow are compared to Reynolds-Averaged Navier-Stokes (RANS) simulations. The temperature measurements were obtained using the planar laser-induced fluorescence (PLIF) technique on the nitric oxide molecule. The experimental setup consists of a 9° compression ramp and a single, 1.6-mmdiameter fuel injector, angled at 81° to the crossflow. The RANS simulation shows good general agreement with the ensemble-averaged experimental data, but discrepancies are significant in regions where large-scale vortex structures dominate the unsteady flow.
