Abstract

The evolution of particle size distribution function (PSDF) was examined in premixed stretch-stabilized flat flames to demonstrate the broadening effect of stretch-stabilized flames for studying soot formation in a pseudo-one dimensional flow configuration. PSDF were calculated in three series of atmospheric-pressure ethylene-O₂-Ar flames with maximum temperatures around 1980 K 2000 K and 2160 K. The measured PSDF presented a strong effect of flame temperature as nucleation and growth of soot was observed to be suppressed towards high temperatures. Simulations using a population balance soot model showed a reasonably good agreement with the 1980 K and 2000 K series of flames but it significantly overpredicted the number density and size of soot in the highest temperature flame. Numerical tests indicated that the discrepancy could be attributed to high-temperature reversibility in surface growth and other processes.
