Swirl-stabilized, nonpremixed ethylene/air flames were investigated at pressures up to 5 bar
to study the effect of different operating parameters on soot formation and oxidation. Focus of
the experiments was the establishment of a database describing well-defined flames,
serving for validation of numerical simulation. Good optical access via pressure chamber
windows and combustion chamber windows enables application of laser-induced
incandescence to derive soot volume fractions after suitable calibration. This results in …
