An augmented reduced mechanism for methane oxidation with comprehensive global parametric validation

摘要

Using a computer algorithm for automatic generation of reduced chaemicstry,an angmented reduced mechanism,consisting of 16 species and 12 lumped reaction steps,has been dvelooped fro methane oxidation from GRI-Mech 1.2. Because the present mechanism consists of a larger number of non-steady-state intermediates than the conventional four-or five-step reduced mechanisms,it exhibits good to excellent performance in predicting a wide rnage of combustion phenomena unde extensive thermodynamical parameteric variations.
