Abstract

Abstract: In order to investigate the atomization and ignition performance of coal-based Fischer-Tropsch synthetic aviation alternative fuels，a single-module rectangular combustor was used to experiment the atomization Sauter mean diameter (SMD) and lean ignition limit of the domestic coal-based F-T synthesis，traditional aviation kerosene RP-3 and 50:50 mixture of both fuels. Experiment results show that，the atomization and lean ignition limit of the three fuels share the same trends under normal temperature respectively，where the decreasing trend of SMD slows after fuel injection pressure reaches 0.5MPa and the expansion trend of lean ignition limit slows after combustor pressure drop reaches 2.0%. Atomization and ignition performance of the F-T fuel are poorer than that of aviation kerosene RP-3，which can be improved by mixing with each other. The atomization SMD empirical relationship was summarized by using the response surface methodology (RSM)，and the effects of atomization and evaporation process on ignition performance were analyzed.

摘要： 为了评价煤基费托合成航空替代燃料的雾化和点火性能，利用单头部矩形燃烧室对国产煤基费托燃料、传统航空煤油RP-3以及二者50:50混合燃料的雾化索太尔平均直径SMD和贫油点火边界进行了实验研究。实验结果显示，常温条件下，三种燃料的雾化SMD和贫油点火边界都有相同的变化趋势，SMD的减小趋势在供油压力达到0.5MPa后变缓，贫油点火边界的扩展趋势在燃烧室压降达到2.0%后变缓；相比航空煤油RP-3，煤基费托燃料的雾化性能和点火性能稍差，通过相互掺混可以得到改善。使用响应面模型(RSM)研究总结了雾化SMD的经验关系式，分析了燃料雾化和蒸发过程对其点火性能的影响。
