Ignition and combustion characteristics of surrogate fuels for kerosene

  • 摘要: 选用了航空煤油(Jet A-1)的3种替代燃料(正癸烷、正癸烷与三甲基苯双组分混合燃料、正癸烷与甲苯双组分混合燃料),并详细分析了这3种替代燃料着火与燃烧的详细化学反应机理(正癸烷单组分燃料为67种组分与344个基元反应,正癸烷与三甲基苯双组分混合燃料为118种组分与527个基元反应,正癸烷与甲苯双组分混合燃料为84种组分与440个基元反应).对这3种替代燃料在激波管中的着火延迟特性及在预混燃烧炉中的预混燃烧过程进行了详细的数值计算,并与实验数据进行了对比分析.同时,比较分析了双组分燃料中两种组分体积分数对着火与燃烧特性的影响.结果表明:在预测Jet A-1航空煤油的着火特性与预混燃烧特性上,两种双组分混合燃料要优于正癸烷单组分燃料.同时,两种双组分混合燃料中两种组分的体积分数对燃料的着火与燃烧特性影响显著.
