| 摘 要： | 本文将相干反斯托克斯(CARS)理论光谱计算和实验光谱分析的方法应用于预混V形火焰燃烧的温度测量实验,利用N2的Q支CARS谱线,使用单脉冲宽带方法获得了预混V形火焰的CARS信号光谱强度特性,测量了V形火焰水平方向和竖直方向上的温度分布特征,从中得出了火焰锋面的厚度,分析了火焰锋面的皱褶与摆动对CARS信号的影响。同时测量了不同燃料系数下V形火焰燃烧产物的温度,得出了温度随燃料系数的变化趋势,为进一步研究预混 V形火焰的结构提供了依据。

| Abstract: | The temperature characteristics of methane-air turbulent premixed V-flames are studied using the Coherent Anti-stokes Raman Spectroscopy methods by Q-branch spectrum of N2. The results show the CARS spectrum characteristics of the V-flames. The temperature distribution of V-flames in horizontal direction and vertical direction are measured, from which the thickness of the flame front is also obtained. The influence of flame front movement on the measured CARS signals is analyzed. Temperature of combustion product under different fuel coefficient is measured. |
