Abstract:

Treatment of chemical reactions in rarefied, nonequilibrium flows has been the subject of significant research. In some cases, proper treatment of reactions is needed to accurately predict overall shock thickness, stand-off, and heat transfer. In other cases, such as when reactants are minor species, the overall flowfield is not affected by details of the reaction model, but a particular radiation signature may be strongly affected. A case of the latter situation is the subject of the present study, and allows for a detailed examination of several issues important to chemical reaction models for rarefied, high-speed flows.
