摘要

我们利用双色平面激光诱导荧光（PLIF）和相干反斯托克斯拉曼散射（CARS）光谱对实验室燃烧器中的 H2 分子进行了测量，测量了甲烷-空气混合物静态大气层流火焰中心部分的空间温度分布，其中甲烷-空气混合物的部分成分初步混合。对空间不均匀火焰的二维 PLIF 和点 CARS 测温数据进行比较分析的结果，以及这些方法在诊断中互补应用的可能性。

Thermometry of Spatially Inhomogeneous Methane–Air Flame Using Two-Color Planar Laser-Induced Fluorescence and Coherent Anti-Stokes Raman Scattering Spectroscopy

Using two-color planar laser-induced fluorescence (PLIF) of OH hydroxyl radicals excited at two wavelengths and coherent anti-Stokes Raman scattering (CARS) spectroscopy of H₂ molecules in a laboratory burner, we have measured spatial temperature distributions in the central section of a stationary atmospheric laminar flame of a methane–air mixture with partial preliminary mixing of the components. The results of a comparative analysis of the data on two-dimensional PLIF and point CARS thermometry of a spatially inhomogeneous flame are presented, and possibilities of complementary application of these methods for diagnostics are shown.
