Abstract
Measurements were made in laminar, N2-diluted ethylene flames doped with m-xylene to determine the effect of the m-xylene on the soot distribution. The soot distribution in the flames was measured using planar laser-induced incandescence that was calibrated with extinction measurements. The nitrogen dilution was used to reduce the effects of extinction on the LII measurements due to the high soot volume fractions observed in high pressure flame studies for undiluted conditions. The experimental variables in the study were the concentration of m-xylene and pressure. M-xylene was added at two concentrations, 2.5% and 5% of the total carbon molar flow rate, while maintaining the total carbon flow rate fixed. At each concentration, flames were studied at pressures from 1 to 5 atm. Peak soot levels were found to increase by a factor of 2.6 at a pressure of 5 atm when the m-xylene concentration doubled. The maximum soot volume fraction in the flame containing m-xylene at a concentration of 5% of the total carbon molar flow rate was measured to be 4.4 ppm at a pressure of 5 atm. The maximum soot volume fractions in the mxylene flames were found to vary linearly with pressure.
