摘要
建立H2/Air混合物燃烧的化学动力学模型,计算与分析了在非平衡等离子体条件下,气体放电产生的活性粒子(O,H)和活性基(OH)在不同当量比下对参与燃烧的组分以及温度和压力的影响,为航空发动机燃烧室等离子体助燃(PAC)实验研究和实际应用提供理论依据.计算结果表明等离子体助燃可以提高反应效率、燃烧温度和火焰传播速率,减少燃烧上升时间,强烈影响H2/Air混合物燃烧.
The chemical kinetic model of H2/Air mixture combustion was established in this article. With the non equilibrium plasma, this paper calculated and analyzed how the active particle （O, H） and radical （OH） produced by gas discharge influenced the components in the combustion, the temperatures and pressures at different equivalent ratios. Therefore, this paper can provide a theoretical foundation for the experimental research and practical application of plasma assisted combustion （PAC） in the aero-engine combustion chamber. The results show that PAC can improve reaction efficiency, combustion temperature and flame spread velocity, reduce the rise-time of combustion and strongly influence H2/Air mixture combustion.
