Kinetics of Nitric Oxide Formation Behind 3 to 4 KM/S Shock Waves
Abstract
A previously published group of 02/N2 shock-tube experiments, wherein the time history of the NO 5 micrometers radiation was measured, has been studied to elicit information about the relevant chemical reactions which produce the radiation. It was found that the calculated radiation was sensitive to the rates used in the Zeldovich mechanism for NO formation, and that the rate measured by Monat et al. for N2 + 0 -- greater than NO + N produced important features of the observed radiation. Vibration-dissociation coupling in this reaction modifies the radiation history in an important way, and is an essential element in obtaining agreement with the experiment. To improve agreement over a range of 02/N2 mixtures, it was necessary to take into account the faster vibrational relaxation of N2 by 02 and 0 collisions and the subsequent effect on vibration-dissociation coupling....
