, et al.. Experimental assessment of the sudden-reversal of the oxygen dilution effect on soot production in coflow ethylene flames. Combustion and Flame, Elsevier, 2017, 183, pp.242-252. <10.1016/j.combustflame.2017 over a wide range of CO 2 replacement of N 2 in the coflowing oxidizer stream, it can be considered a distinct characteristic for the assessment of numerical simulations incorporating soot formation and oxidation models. As an original database, the concomitantly measured soot temperature and volume fraction distributions are attached to the present paper as supplemental materials, thus documenting the aforementioned transitions for the whole range of CO 2 content of the coflow investigated.
