乙烷对冲扩散火焰中PAHs的生成

FORMATION OF PAHs IN OPPOSED FLOW DIFFUSION FLAMES OF ETHANE

本文使用详细的化学反应机理模拟了C2H6／O2／N2／AR层流对冲扩散火焰中多环芳烃的生成动力学过程。反应机理包括96种组分的502个基元反应。通过数值计算分析了层流对冲火焰的结构和主要反应物、中间物质和反应产物的浓度变化,并与相关文献的实验结果进行了比较。结果表明,数值模拟在燃烧过程和PAH生成规律上与实验结果是一致的,但在某些组分的定量预报上存在一定的差别。

This paper simulated polycyclic aromatic hydrocarbons formation in C2H6/O2/N2/AR laminar opposed flow diffusion flame using detailed chemical kinetic mechanism. The mechanism includes 96 species and 502 reactions. Through numerical modeling, analysis of opposed flame structure and concentration changes of main reactants, intermediate and products has been performed. Comparison of numerical results with experimental data reported in literature has been completed as well. Results showed modeling results were consentaneous with the experimental data in quality, but have some differences in certain species in quantity.
