Abstract

A detailed quasiclassical trajectory (QCT) study of the first Zeldovich reaction, N 2 + O → NO + N under re-entry flow conditions is carried out. Emphasis is given to investigating the effect of high temperature and thermodynamic nonequilibrium on the rate constant of this reaction. A modified Arrhenius expression for the rate constant for this reaction is presented based on the QCT data. The agreement with the experimental data is very good. However, at high temperatures (T > 12,000 K) the predicted rate constant is greater than the rate constant proposed by Park by almost an order of magnitude. An analytical expression describing the dependence of the rate constant on the vibrational, rotational and translational temperatures is also given. Finally, the product vibrational distribution of the NO formed by this reaction hi nonequilibrium flows is obtained. It is found that the vibrational temperature of NO formed behind a strong shock is much higher than the overall gas vibrational temperature.
