Nonequilibrium Gas-Surface Interactions at HighTemperature, VKI Plasmatron facility and MUTATION++ Library
Abstract
Despite available flight data on material performances and efforts in material modeling, prediction of the heat flux to hypersonic vehicles remains a critical problem. Ground testing in plasma wind-tunnels is currently the only affordable option for qualification of thermal protection materials and validation of computational models. We propose combined theoretical, numerical, and experimental research that will allow us to improve our understanding of the complex gas-surface interaction phenomena. In particular, we propose some major advancement of the experimental investigation of the response of carbon and silicon carbide materials in high enthalpy flows, including relevant modeling support. The two main objectives of our research are: 1) to review existing experimental data sets that the VKI group has already gathered in the Plasmatron facility, including modeling tools developed for Gas-Surface Interaction phenomena, and 2) to perform additional experiments, possibly of new Thermal Protection System samples, tailored to specific objectives for validation of advanced numerical models. Our tasks will be carried out in synergy with a US team led by Prof. Schwartzentruber, in relation to the AFOSR Grant FA9550-17-1-0057 on “Nonequilibrium Gas-Surface Interactions at High Temperature."
