摘要
Using automatic generation software for hydrocarbon oxidation mechanisms, a detailed mechanism for the high-temperature combustion of n-dodecane was developed. A semi-detailed mechanism consisting of 202 species and 738 reactions was obtained by rate-of-production analysis while a skeletal mechanism including 53 species and 228 reactions was obtained using path flux analysis. Both the semi-detailed mechanism and the skeletal mechanism were validated by comparing simulation results including the ignition delay time, high-temperature pyrolysis, and the laminar flame speed with experiments. The current mechanism generation method and the generated semi-detailed and skeletal mechanisms for n-dodecane should be useful in computational fluid dynamics simulations. Finally, the major reaction pathways of n-dodecane oxidation and the important reactions in the ignition process were investigated by reaction path analysis and sensitivity analysis, respectively.
