N2 - The paper deals with modeling of vibration-chemical coupling in mixtures containing CO2 molecules. The temporal vibrational and chemical relaxation in the five-component and three-component space-homogeneous mixtures CO2/CO/O2/C/O and CO2/CO/O is studied taking into account vibrational energy transitions, dissociation, recombination and exchange chemical reactions. The vibrational-chemical coupling in considered mixtures is studied on the basis of three-temperature, two-temperature and one-temperature vibrational CO2 distributions. Governing equations for macroscopic mixture parameters in the three-temperature, two-temperature and one-temperature approximations are solved numerically for different initial conditions. Comparison of the results obtained in three approaches showed the in uence of non-equilibrium vibrational distributions on chemical reaction rates and on the temporal variation of the gas temperature, mixture composition and vibrational temperatures in two considered mixtures.
