Abstract:A reduced chemical kinetic model was obtained by reducing the detailed chemical kinetic model GRI-Mech 1.2 for the combustion of methane based on quasi-stationary state approximation(QSSA).This reduced model is composed of 18 species with 14 global reactions.The comparisons between the reduced model and the typical experimental results were made.Computational results of the reduced model were also compared with that of the detailed model by adopting the uniform experimental design technique.The little difference between these results showed that the reduced model using QSSA has the ability to represent efficiently the reaction mechanisms of detailed element reaction model.Therefore,the reduced model is of high precision and the can be used reliably and efficiently.
Keywords:Methane  Combustion  Ignition delay  Reduced chemical kinetic model~+
