Abstract:

Soot in engines is present in a rich premixed flame near the fuel injector followed by a diffusion flame where it is burned out. To mimic this structure we perturbed an atmospheric-pressure ethylene diffusion flame by progressively adding oxygen in the fuel stream, while holding constant peak temperature and stoichiometric mixture fraction.
