The proposed project will develop advanced modeling capabilities for hypersonic flow problems, specifically for predicting aerothermodynamic flow field for estimation of drag, thermal and structural loads, and for surface interactions. A quantum-to-continuum suite of tools that develop molecular relaxation models based on computational chemistry and quasi-classical trajectory (QCT) analysis will be developed. A novel automatic potential energy surface construction approach will be used to construct ab-initio set of calculations on-the-fly will be implemented. A massively-parallel QCT technique will be used to obtain state-specific reaction rates with estimated uncertainties, and can be further reduced to obtain lower-order models. An application programming interface (API) will enable coupling to external CFD codes. As part of a hierarchy of demonstration cases, direct numerical simulation (DNS) and Reynolds-averaged Navier-Stokes (RANS) computations will be conducted.
