Distribution of the number of primary particles of soot aggregates in a nonpremixed laminar flame

Experimental data on the probability distribution of N, from which Ng and σ2g 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.
