摘要 为了阐明氢气添加对国产RP-3航空煤油燃烧特性的影响,在定容燃烧反应器中实验测量了初始压力为0.1MPa、初始温度分别为390,420K、当量比范围为0.8~1.5时RP-3航空煤油/氢气混合气的层流燃烧速度与马克斯坦长度,分析了掺氢比对火焰发展结构、层流燃烧速度及马克斯坦长度的影响.结果表明:随着掺氢比的提高,在火焰发展过程中,火焰前锋面逐渐出现裂纹或褶皱,火焰的不稳定性逐渐增强;随着混合气当量比或掺氢比的升高,RP-3航空煤油/氢气混合气的马克斯坦长度逐渐减小;当混合气当量比从0.8升高至1.5时,RP-3航空煤油/氢气混合气的层流燃烧速度呈现先增加后降低的趋势,当量比为1.2时混合气的层流燃烧速度达到最大;同时,随着初始温度或掺氢比的升高,RP-3航空煤油/氢气混合气的层流燃烧速度逐渐升高。 In order to illustrate the effects of acteristics of RP-3 kerosene, the laminar burning hydrogen addition on the combustion char- velocity and Markstein length of RP-3 ker- osene/hydrogen mixture were investigated experimentally in a constant volume combustion bomb. The experiments were performed at initial pressure of 0.1 MPa, initial temperatures of 390, 420 K and over the equivalence ratios range of 0.8-1.5. The influences of hydrogen addition ratio on the flame structure, laminar burning velocity and Markstein length were in- vestigated. Results showed that some cracks or folds appeared on the flame front in the flame developing process, and the instability of flame increased with the growing hydrogen addition ratio. Increasing the equivalence ratio or the hydrogen addition ratio decreased the Markstein length of RP-3 kerosene/hydrogen mixture. Furthermore, with the equivalence ratio increasing from 0.8 to 1.5, the laminar burning velocity of RP-3 kerosene/hydrogen mixture increased initially and then decreased gradually. The highest laminar burning veloci- ty was measured at fuel rich condition (the equivalence ratio was 1.2). At the same time,with the increase of initial temperature or hydrogen addition ratio, the laminar burning veloc- ity of RP-3 kerosene/hydrogen mixture showed an increasing trend.
