Methane Reaction Mechanism Reduction Using Paths Flux Analysis of Three Generations Method
Based on path flux analysis and the preselected species,according to the sum of production and consumption fluxes of other species to the preselected in one generation,two generations and three generations reactions,a new chemical mechanisms reduction method has been developed.The detailed mechanisms of methane is reduced by using path flux analysis of three generations method and the reduced mechanisms are compared with detailed chemical mechanisms and the reduced mechanisms using path flux analysis of two generations.The comparison results prove that the reduction method based on path flux analysis of three generations is more accurate.The comparison results of the accuracies of path flux analysis of three generations and two generations respectively in specific conditions show that path flux analysis of three generations has more accuracy when the ignition delay time is short.
