Reaction rates and cross section databases constructed from ab initio potential energy surfaces enable a state-based description of chemical reactions, energy level dynamics, transport, and radiation in strong non-equilibrium flows.
A mesoscale model for gas-surface interactions combines surface processes and gas-phase energetics to characterize oxidation mechanisms and oxidation rates of advanced TPS materials.
MATERIAL RESPONSE & ANALYSIS
Advanced experimental techniques aim to elucidate complex coupled phenomena in porous and fibrous TPS materials, including radiative and conductive heat transfer, flow transport in the Knudsen regime, and diffusion under extreme conditions.
Machine learning and neural networking techniques enable rapid identification of new physical insights and physical models in complex coupled systems.
MATERIAL ARCHITECTURES & FABRICATION
Novel fabrication techniques and manufacturing methods for high-temperature materials and material architectures enable tailorable TPS designs.
The dynamic interaction between a high-speed flow grazing thermo-mechanically compliant panels are studied using direct numerical simulation techniques to understand how they impact boundary layer transition, shock-boundary layer interaction, panel flutter, and panel snap-through.
