Abstract

A high temperature quasiclassical trajectory (QCT) study is done for the second Zeldovich reaction, O₂ + N → NO + O to better model its kinetics in hypersonic flows. The thermal rate constants obtained agree well with the available experimental data and various recommended expressions. It is found that vibrational nonequilibrium makes only small differences in the rate of this reaction. The average vibrational energy of NO formed by the O₂ + N → NO + O reaction is always higher than the reactant vibrational energy. Also, the product NO vibrational distribution is non- Boltzmann. It is then shown that the vibrational energy disposal due to O₂ + N → NO + O reaction makes a significant difference in the NO vibrational temperature in re-entry flowfields.
