Reduced-species mechanisms for the combustion of cyclohexane using the Local Self Similarity Tabulation method

Abstract

We utilize the Local Self Similarity Tabulation (LS2T) method to drastically downsize the number of species involved in a detailed kinetics mechanism of cyclohexane. Reduced-species mechanisms of 20 and 15 species are constructed out of the 1081 species involved in the detailed kinetics one. Their performance is compared to that of the detailed kinetics one for a lean (φ=0.5), stoichiometric (φ=1.0), and rich (φ=2.0) cyclohexane/air fresh mixture at an initial temperature of 900 K and initial pressures of 20 and 40 bar.
