氢火焰空间分辨多组分和温度分析
We report on spatially resolved simultaneous measurements of temperature and majority speciesconcentrations along a line segment in a premixed laminar H2-air flame. The results are obtained fromRaman and Rayleigh scattering by using a narrow-band KrF excimer laser and a spectrally and spatiallyresolving detector system that consists of a high-throughput spectrometer and a gated, intensified,two-dimensional CCD camera. The data presented here are integrated over 100 laser shots. Absolutedensity profiles of N2, 02, H20, and H2, as well as temperature profiles at various heights through theflame, are presented. A discussion of the required calibration procedures and a summary of thenecessary spectroscopic background are also included in this paper.
