Title

Surface Growth, Nucleation And Surface Oxidation Of Tem-Observable Primary Soot Particles In Flames

Abstract

Soot formation and oxidation must be understood to develop reliable computational combustion methods for nonpremixed (diffusion) flames involving hydrocarbon fuels. Motivated by this observation, the present investigation extended earlier work on soot formation and oxidation. The surface reaction and nucleation properties of TEM-observable primary soot particles were studied in laminar flame environments. Experimental conditions involved round laminar premixed and nonpremixed (diffusion) flames fueled with a variety of hydrocarbons, gas temperatures of 1500-2350 K, burning in oxygen/inert-gas mixtures at pressures of 0.1-1 atm. Observations did not include soot precursor particles but were limited to TEM-observable primary soot particles having diameters > 10 nm. The following properties were measured along the axes of the flames: soot volume fractions, soot temperatures, soot structure, concentrations of major stable gas species, concentrations of some radical species (H, OH, and O) and flow velocities. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
