CORRELATIONS BETWEEN PARAMETERS OF GLOBAL AND ELEMENTARY CHEMICAL KINETIC MECHANISMS.

The concept of and necessity for global reaction kinetics results directly from the complexity of most combustion reactions and the complicated fluid mechanical situation in which some knowledge of heat release and chemical rates is required. The assumption commonly invoked is that the course of chemical kinetic events may be described in terms of a few of the principal reactants and products, c//i, in a functional relation with much the same form as an elementary reaction process. The present analysis has shown it possible to correlate the parameters of two fundamentally different chemical kinetic models. In the present context, these correlations were useful for identifying which elementary reactions control the values of global parameters in an overall reaction scheme. For the moist CO oxidation example chosen, this information explains the complex dependence of kov on temperature.
