摘要
本文利用CO_2红外气体分析仪和取样管对高密度喷气燃料和常规喷气燃料在直流喷嘴下游的浓度场分布进行了测量,就气流速度、油压降和下游距离对浓度场分布的影响进行了对比研究。试验结果表明,在相同工况下,常规喷气燃料的最大浓度值比高密度喷气燃料的大;气流速度和油压变化对高密度喷气燃料最大浓度点穿透深度的影响大于对常规喷气燃料的影响。
In the experiment, CO2 infrared analyzer and sampling probe are used to measure fuel spray characteristics of high-density kerosene and aviation kerosene downstream from a simple orifice injector. The effects of air flow velocity, pressure drop and distance from the injector on the fuel concentration distribution are studied. The test result show that under same condition the maximum concentration for conventional jet fuel is higher than that for high-density kerosene and the effects of air flow velosity and fuel pressure on penetration of maximum concentration are stronger for high-density kerosene than for conventional jet fuel.
