An Experimental Investigation of Soot Formation During Nonpremixed Turbulent Combustion of Hydrocarbon Fuels
Although practical combustion devices involve turbulent conditions, crucial soot investigations have generally been based on the data obtained from laminar flames with relatively limited number of studies in the literature on turbulent flames. Motivated by the need for data that can allow proper characterization of soot properties within the fuel-rich regions of turbulent flames, optical experiments were carried out within hydrocarbon-fueled nonpremixed turbulent jet flames. Specifically, two gaseous fuels, ethylene and acetylene, were burned at relatively high Reynolds numbers in air at atmospheric pressure. In-situ diagnostics included laser scattering and extinction techniques to determine the soot field at various axial and radial positions in these flames. The findings are relevant not only to developing advanced computational models for accurate predictions of radiative transfer but also to controlling and predicting performance and pollutant emissions in combustion systems.
