Technology for Sustained Supersonic Combustion Task Order 0006: Scramjet Research with Flight-Like Inflow Conditions

Abstract : This report focuses on the impact of shock distortion on various high-speed flows for scramjet applications. Simulations consist of shocked sonic injection into a supersonic crossflow, shock distorted cavity-assisted fuel mixing and combustion, and novel experimental designs. Hybrid large eddy simulation/Reynolds-averaged Navier-Stokes (LES/RANS) turbulence modeling techniques are highlighted and their ability to capture the unsteady nature of high-speed turbulent flows is investigated. This task provided extended experience and knowledge of using hybrid LES/RANS techniques for internal high-speed flows. These results also will provide valuable information for better understanding the complicated physics of shock boundary layer interactions and mixing in high-speed flows in detail that experiments cannot easily provide.
