Wang, Dashan 2004 Combustion and Flame 138 195-198 Experimental data on the probability distribution of N, from which Ng and ��2g are derived, for soot aggregates sampled within a laminar diffusion flame environment have not been published. The objective of the present investigation is to report such experimental data and to gain a better understanding of the distribution of N of soot aggregates thermophoretically sampled from a laminar ethylene/air diffusion flame by analyzing thousands of aggregates in TEM (transmission electron microscopy) images. http://dx.doi.org/10.1016/j.combustflame.2004.04.008
