Abstract
The effect of oxygen addition to the fuel on the sooting structure of a counterflow diffusion flame has been studied by soot particle number density, average particle diameter, soot stagnation streamline. Data from various ethylene and propane flames (with a maximum of 10% oxygen added to the fuel stream) are presented. Whereas oxygen addition in ethylene flames is found to increase the soot loading dramatically, a slight decrease is observed in propane flames. The increase in soot volume fractions in ethylene flames is attributed to the presence of larger soot surface areas available for surface growth reactions.
