- Abstract
- Local measurements of mean and RMS emission intensities, transmittances, emission temperature, and soot volume fractions based on emission and absorption in toluene flames burning in a pool configuration are reported. Radical profiles of these quantities at six axial stations within the flame are selected for discussion. The results show large fluctuations in temperatures and soot volume fractions at all locations including those near the liquid surface. Differences between the soot volume fractions based on emission and those based on absorption indicate the presence of large quantities of relatively cold soot at all positions.
