The in-situ, highly spatial resolution, two-dimensional distribution of OH(X) species in a premixed liquified petroleum gas/air flame is reported. The measure- ment was performed by the saturated laser induced fluorescence method with the tran- sitions of OH (A~(2∑~+), v′=0←→X~(2Π), v″=0). The intensities of the broadband emission reflected the local concent ations of OH(X) in the flame.
The result showed that OH(X) populated at the rim of the visual flame.
State-to-state reactions related to OH(X) radical in flame condition are discussed. OH(X) was produced from the oxidation of small hydrogen-containing radicals. The consumption of OH(X) seemed via reaction (10) and (11). The population of OH(A) species is also discussed.
