摘要

摘要: 为了获得RP-3航空煤油与其模型燃料的雾化特性，在燃油喷嘴雾化激光测试平台上对相对喷射压力分别为200、400、600、800 kPa时，RP-3航空煤油及由14%正癸烷/10%正十二烷/30%异十六烷/36%甲基环己烷/10%甲苯（摩尔分数）组成的模型燃料的雾化特性（雾化锥角、雾化粒度、油滴速度）进行了试验测试，并完成了两者的对比分析。结果表明：随着相对喷射压力的升高，RP-3航空煤油与其模型燃料的雾化锥角与油滴速度逐渐增大，索太尔平均直径（SMD）逐渐减小；随着离喷嘴出口轴向距离的增加，RP-3航空煤油与其模型燃料的SMD值与油滴速度逐渐减小；在各相对喷射压力下，模型燃料的雾化锥角与油滴速度要略高于RP-3航空煤油，SMD值则要略低；但是，两者之间差异较小，说明该模型燃料的雾化特性与RP-3航空煤油有较高的相似性。

Abstract: In order to obtain the atomization characteristics of RP-3 kerosene and its surrogate fuel，the atomization characteristics （including the atomization cone angle，atomized particle size，droplet velocity） of RP-3 kerosene and its surrogate fuel （14% n-decane/10% n-dodecane/30% iso-cetane/36% methylcyclohexane/10% toluene，mole fraction） were experimentally tested and compared in the laser test platform of fuel nozzle atomization at the conditions of relative injection pressures of 200，400，600，800 kPa.The results showed that with the increase of relative injection pressure，the atomization cone angle and droplet velocity of RP-3 kerosene and its surrogate fuel increased gradually，but the value of Sauter mean diameter （SMD） decreased.Meanwhile，with the increase of the axial distance from the nozzle outlet，the SMD value and droplet velocity of RP-3 kerosene and its surrogate fuel decreased gradually.Under different relative injection pressures，the atomization cone angle and droplet velocity of the surrogate fuel were slightly higher than those of RP-3 kerosene，and the SMD value was slightly lower.However，the small difference indicated that the atomization characteristics of the surrogate fuel had a high similarity with RP-3 kerosene.
