Abstract

The simulation of the combustion processes is rather complex when detailed mechanisms are used. The reduced mechanisms of reaction with a restricted number of reactions are thus of significant importance. These reduced mechanisms are composed of some steps, which imply a limited number of chemical species. In this paper, the method of CSP [1, 2] was applied to reduce a detailed mechanism GRI-3.0 [3]. To identify the species in a stationary state and the fastest elementary reactions, this technique requires as an input the detailed mechanism and the flame model. Based on an algorithm of CSP, several reduced mechanisms with various steps were given. The mechanism with 5-stages is regarded as a base of the other mechanisms with more reactions
