| 摘 要： | 利用自发振动拉曼散射技术测量了煤油燃烧场主要组分的摩尔分数。基于355nm激光激发振动拉曼散射建立了自发拉曼散射实验系统,测量了空气中主要组分的摩尔分数,分析了该技术的测量精度;测量了煤油蒸气在355nm激光激励下产生的荧光光谱,分析了荧光信号对拉曼信号的干扰;对不同燃烧条件下的煤油燃烧场进行了诊断,获得了贫油条件下煤油燃烧场主要组分(N2,O2,H2O,CO2等)的拉曼光谱,计算了组分摩尔分数及其随燃烧时间的变化规律。

| Abstract: | A spontaneous vibration Raman scattering(SVRS) system for the simultaneous measurement of the major species concentrations in kerosene combustion was presented. The accuracy of SVRS was analyzed by measuring the major species concentrations in the air. The fluorescence characteristic of kerosene induced by 355 nm laser was obtained and analyzed. Under different burning conditions, the kerosene combustion was diagnosed by SVRS, the Raman spectra of the major species (N2, O2, H2O,CO2) in lean kerosene combustion were obtained, and the major species concentrations during the combustion process was calculated. |
