Abstract

The primary particle diameter and the soot structure are determined from three light scattering measurements and one extinction measurement at different heights in a nonsooting laminar ethylene diffusion flame. The analysis of the data utilizes the albedo determined from the scattering measurements. The primary particle diameter and soot structure are calculated using an assumed constant value for the fractal dimension and the fractal prefactor. The values for the primary particle diameter obtained from the in-situ measurements in this study compare well with those obtained from transmission electron microscopic measurements of thermophoretically sampled soot aggregates in a previous study at all heights in the diffusion flame, while the calculated soot structure parameters compare well with the previous study only in the mid-flame region.
