Abstract

Shock layer radiation is an important heating mechanism for entry probes to most planetary destinations and re-entry to Earth from beyond low Earth orbit. Our understanding of shock layer radiation phenomena has improved tremendously over the last decade thanks to NASA investment in fundamental radiation research through Entry Systems Modeling’s (ESM) Shock Layer Kinetics and Radiation (SLKR) task. This talk will overview the recent activities within SLKR, including validation of models through ground testing, flight instrumentation and remote observations; development of first principles ab initio calculations for reaction mechanisms and spectroscopic databases and advancing numerical and computational methods for prediction of radiation in reacting hypersonic flows. 1 Sr. Research Scientist, Aerothermodynamics Branch, and AIAA Associate Fellow.
