Abstract
Chemiluminescence emission from opposed jet burner flames was measured by a charge coupled device (CCD) camera with an image intensifier. Radial profiles of the emission intensity of OH, CH and C2 radicals were obtained by the Abel inversion of the side-on observations. The profiles of emission intensity of these radicals are similar, and each maximum is located at the center of the flame zone. The emission of C2 and CH radicals produced in the early stage of the combustion reaction was observed even on the burned-gas side of the flame zone where the mean temperature is significantly high, suggesting that unburned mixture exists on the burned-gas side of the flame zone. It was found that the profiles of OH emission intensity and NO concentration are similar. This fact suggests that NO originating from the prompt NO mechanism is predominant in the distributed reaction zone.
