✦ Synopsis

We have found that soot particle inception in our premixed ethylene flame occurs in a region where the 02 concentration is of the order of 1% and that particle inception ceases as the 02 mole fraction drops much lower. This relationship between soot formation and 02 concentration is in qualitative agreement with shock tube results. The net specific surface growth rate is close to zero in the inception zone, a fact that is consistent with oxidation of soot by 02.
