NTIS: PB 221 885 :10 pages
Concentration profiles of low-pressure, slightly lean ch4-o2-ar flames have been measured in situ for the following unstable species: oxygen atom, hydrogen atom, hydroxyl radical, methyl radical, and formyl radical. The observed maximum mole fractions were 2.0 X 10-2 for h, 1.1 X 10-2 for oh, and 0.8 X 10-2 for o; the maxima occurred in the recombination zone. Methyl and formyl radicals have maximum mole fractions in the reaction zone of 2.2 X 10-3 and 6 x 10-5, respectively.
