Abstract :
Two-temperature rate coefficients for exchange reactions of oxygen and nitrogen molecules and atoms were studied. Two-temperature and state-to-state nonequilibrium factors of exchange reactions were introduced. Different models for state-dependent reaction rates were used for calculation of two-temperature coefficients and nonequilibrium factors. The results were used for numerical modelling of three-temperature air flows behind shock waves.
