摘要
A reaction scheme reproducing methane combustion by computer simulation under a wide range of stoichiometric ratio has been proposed and applied to flat methane-air premixed flames to elucidate factors determining their propagation mechanisms and the role of C2 reaction pathways. Main methane combustion reactions, which progress sequentially from the fuel to carbon dioxide, are inhibited at low temperatures due to retarded production of oxygen atoms which are necessary for the oxidation of methyl radicals. The role of C2 routes have been investigated by comparison of the results obtained by use of the C2 scheme and a simplified C1 scheme. Some of the methyl radicals are once recombined to ethane but most of the produced ethane is dissociated again to methyl via ethyl radicals. Then the C2 routes work as a temporary storage of species and hinder the main combustion reactions which go through C1 species.
