Summary
Results of numerical integrations of the coupled chemical rate equations and gasdynamic equations are presented for nozzle airflows. Composition histories are shown for a kinetic mechanism including 6 species and 14 reactions. The freezing process is complex because the N-O shuffle reactions couple the disociation-recombination reactions. In many cases where the energy in N dissociation is significant, the fast shuffle reactions prevent N atom freezing which would otherwise occur if 3 body recombination were the only process operating. Nitric oxide concentrations undershoot the equilibrium values in many cases. Oxygen freezing is affected little by the shuffle reactions. Results suggest the applicability of simplified chemical kinetic models based on the shuffle reactions for airflows in various regimes of the initial state.
