Abstract

In premixed laminar methane–air flames time- and space-resolved oxygen concentration and temperature measurements have been performing using a Q-switched ruby laser Raman probe. Concentration and temperature have been evaluated from selected intensities of the Raman Stokes vibrational Q-branch. Good agreement was found with comparative suction probe concentration measurements and with additionally performed optical (Rayleigh, cw laser Raman) temperature measurements. For fuel-lean flames with various equivalence ratios the pulsed laser Raman probe could be used for controlling stoichiometric flame conditions. Selecting three different narrowband interference filters appropriately, a simultaneous determination of vibrational and rotational temperatures seems possible.
