The Mechanism Analysis of Non-thermal Equilibrium Plasma on Ignition of Methane

非平衡等离子体可以产生多种活性物质。这些产物会对燃烧产生作用。为探索甲烷放电产物(H自由基)对甲烷点火性能影响规律,利用零维、均质、完全混合其模型,对甲烷点火过程进行数值模拟。研究了甲烷放电产物(H自由基)和其不同的初始浓度对甲烷/空气混合燃气的点火延迟时间的影响规律。借助反应路径分析和敏感度,分析揭示非平衡等离子体生成自由基,对甲烷点火性能的影响及其中涉及的化学反应机理。

Non-thermal equilibrium plasma can produced many kinds of radicals. Those radicals enhanced combustion. To investigate the effect on non-thermal equilibrium plasma production （H radicals）on ignition of methane, the closed reactors was applied. This article sim- ulated the non-thermal equilibrium plasma on ignition of methane and analyzed the influence of on some plasma-produced species（ H radi- cals） and different initial density on ignition. Then, using reaction path analysis and sensitivity analysis, the results have disciplinarian on the detailed kinetic enhancements of radicals on non-thermal equilibrium plasma on ignition of methane/air.
