It is not possible<br>to reproduce flight conditions in ground-testing facilities and flight-testing is expensive. As a result,<br>advanced aerodynamic and chemical kinetics modeling, combined with high performance computing,<br>plays a critical role in advancing hypersonic flight science. Considerable recent effort has been devoted<br>to understanding and modeling internal energy relaxation and dissociation in hypersonic flows using<br>first-principles calculations. In the past ten years, 23 potential energy surfaces (PESs) that govern the<br>collision dynamics of relevant air species (N2, N, O2, O, and NO) in the ground electronic state have<br>been developed and used to simulate dissociating nitrogen and oxygen gas. These simulations have<br>predicted the precise coupling between gas internal energy and chemical reactions including nonBoltzmann effects. Recent experimental measurements are now able to validate these non-Boltzmann<br>coupling predictions for the first time.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-80.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-80.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Thomas E.
