The Mechanism Analysis of O Radical Effect on Ignition of Methane/Air Mixture

Abstract:

In order to show the physical mechanism of O radical on ignition of methane/air mixture, based on GRI-Mech3.0, the ignition were carried on by solving the mode of the closed reactors. It was found that the influence law on O radical effect on ignition of methane/air mixture. The numerical results indicate that the ignition time reduced about 94.7% by adding radicals of the 0.5% O. By using reaction path analysis and sensitivity analysis, the results have disciplinarian on the detailed kinetic enhancements of radicals on O radical on ignition of methane/air.
