✦ Synopsis

Radiation intensity and emissivity measurements were made for a DF-2 flame in a model gas turbine combustor. This same flame was also mapped lor temperature and soot mass concentration. Finally. a movable, cold traversing background was used to determine the contribution to total radiation intensity from the individual sections of the flame. A computer program which integrated the radiative transfer equation with respect to path length and frequency was then used to predict a soot profile, based on temperature, radiation intensity, emissi~it>, and cold traversing background rcsult~,. Though the predicted ~,oot concentrations were considerably higher than the measured levels, the agreement between the predicted and measured shapes of the soot profile was good. The discrepancy between predicted and measured soot mass concentrations was attributed to soot particle deposition in the probe.
