Combustion Mechanism and Kinetic Modeling Study of Methyl Cyclohexane at High Temperature

Abstract

Abstract: At first, relevant discussions on combustion reaction rules at high temperature of alkanes and naphthenes were presented in this study. According to these rules, a program named ReaxGen was developed for automatic generation of the detailed mechanisms for large hydrocarbons. Secondly, the detailed combustion mechanism of methyl cyclohexane at high temperature was constructed using this program. Then, the influence of ignition temperature, ignition pressure, mole fraction of fuel and equivalence ratios upon the ignition delay time for methyl cyclohexane combustion at high temperature were investigated by a kinetics simulation method using shock tube. In addition, equilibrium calculations were also performed in order to obtain the concentration of product and adiabatic flame temperature. Finally, these calculated results from our mechanism were compared with the literature experimental results and those from other mechanisms available.
