Abstract:

Spontaneous Raman spectroscopy has been used to measure temperature and NO, O, and N concentration profiles in lean to stoichiometric premixed laminar hydrogen-nitrous oxide flames. Relative concentration profiles for OH were also obtained for these flames by use of laser induced fluorescence. The present NO concentration results for the Stoichiometric flame agree with previous NO measurements obtained by a different optical technique. Profiling these species for various equivalence ratios provides a further test for flame modelers.
