    Abstract

    Detailed N/O kinetic sub-mechanism (for species containing only nitrogen and/or oxygen atoms) was updated on the basis of a literature survey of new experimental data for pertinent reactions. It was shown that without any adjustment of the rate constants the proposed N/O kinetic mechanism provides at least satisfactory agreement with different sets of experimental data on NOx decomposition. Burning velocities of pure N2O were measured at a pressure of 5 atm for further validation of the mechanism. It was found that the mechanism substantially underpredicts these data by a factor of approximately two. Possible reasons for this disagreement are suggested.
