摘要

摘要: 为了研究初始温度470K、初始压力0.1MPa下乙醇掺混对航空煤油层流火焰燃烧特性的影响，文中利用定容燃烧弹设备结合仿真进行对比分析。结果表明，乙醇的加入显著提升了航空煤油的层流火焰燃烧速度，但仿真结果与试验数据之间存在较大的偏差，在低当量比时尤为严重，需进一步优化机理。在此基础上通过敏感性分析，发现对层流火焰燃烧速度影响较大的4个基元反应，通过对4个基元反应的参数进行调整，修改得到新模型，该模型与试验值存在较好的吻合度。

Abstract: To study the effect of ethanol blending on the combustion characteristics of aviation kerosene laminar flame at an initial temperature of 470K and an initial pressure of 0.1MPa, a constant volume incendiary bomb was used in this paper to conduct a comparative analysis combined with simulation. The results show that the addition of ethanol significantly improves the laminar burning velocity of aviation kerosene, but there is a large deviation between the simulation results and the experimental data, especially at low equivalence ratios, and the mechanism needs to be further optimized. On this basis, a sensitivity analysis was carried out, finding a great influence of four elementary reactions on the laminar burning speed. Adjusting the parameters of the four elementary reactions, a new model was obtained, being in good agreement with the experimental values.
