摘要
碳氢燃料的燃烧是航空发动机的动力来源。采用ICCD瞬态光谱探测系统和激波管平台,在点火压力1.0~20.0 atm,点火温度650~1700 K,燃料摩尔浓度0.1%~2.0%和当量比0.2-2.0实验条件下,研究了碳氢燃料的点火和燃烧特性。研究结果对了解碳氢燃料的燃烧性质,对航空发动机燃烧室的设计和对验证燃料燃烧反应动力学机理非常重要。
The combustion of hydrocarbon fuels is the propulsion source for aeroengines.Using an intensified spectroscopic detector ICCD and a shock tube system,ignition and combustion characteristics of hydrocarbon fuels were studied.Experimental conditions included ignition pressures of 1.0~20.0 atm,ignition temperatures of 650~1700 K,fuel molar concentrations of 0.1%~2.0%and equivalence ratios of 0.2~2.0.Research results contribute to understanding the combustion properties of hydrocarbon fuels,and provide experimental data valuable for designing the combustor of aeroengine and validating combustion reaction kinetics mechanisms of fuels.
