Abstract

Experimental data are presented for the effects of addition of hydrocarbon fuels on soot volume fractions for a nitrogen-diluted ethylene flame over a range of pressures from 1 to 5 atm. The fuels investigated were m-xylene, dodecane, a 77% dodecane/23% m-xylene mixture, and JP-8. The mixture was chosen to match the Threshold Soot Index of JP-8. The experimental approach was designed to investigate the effects of fuel addition as a perturbation to the base flame by keeping the amount of carbon added as liquid fuel small compared to the total carbon flow rate. Each liquid fuel was studied at two concentrations. The two concentrations used were chosen such that 2.5% and 5% of the total carbon flow rate was supplied by the liquid fuel. Total carbon flow rate was held constant for all the flames. The soot volume fractions were measured using planar laser induced incandescence. The experimental results indicate that the increase in peak soot levels caused by the substitution of the liquid fuel for ethylene is roughly first order with respect to the amount of fuel added. The peak soot volume fractions for the fuels generally follow the trends expected from TSI measurements for each component. The maximum soot volume fractions were found to vary linearly with pressure from 2 to 5 atm.
