本文提出了40%(摩尔分数，下同)正癸烷、42%正十二烷、13%乙基环己烷和5%对二甲苯的四组分RP-3航空煤油替代燃料模型，并通过实验充分验证了替代燃料模型与实际RP-3航空煤油在理化特性上的相似性。采用对冲火焰实验台架，测量了RP-3航空煤油以及四组分替代燃料的层流火焰传播速度。对比结果表明本文提出的替代燃料能够准确描述实际RP-3航空煤油的燃烧速率。进一步发展了包含168组分、1089反应的半详细反应动力学模型，验证结果表明本文机理能够准确预测RP-3航空煤油着火延迟时间和火焰传播速度。

A four-component RP-3 aviation kerosene surrogate fuel, comprising 40% n-decane/42% n-dodecane/13%ethycyclohexane/5%p-xylene (molar fraction), was presented. Experiments showed the physical and chemical similarity of the surrogate fuel to the real RP-3. Counterflow, twin-flame experiments were used to determine the laminar flame speeds of both the real and the surrogate fuel and showed that the surrogate fuel accurately modeled the burning rate of real RP-3. A semi-detailed chemical reaction mechanism for ignition and oxidation of the RP-3 surrogate fuel that consists of 168 species and 1089 elementary reactions has been developed. Experimental results validate the model and highlight its ability to accurately predict the ignition delay times and laminar flame speeds of real RP-3.
