Abstract:

This paper presents an overview of our work concerning light scattering studies of soot in flames. We have developed static light scattering (SLS) to an ability where a complete in situ characterization of soot cluster morphology can be obtained. The morphological parameters we can measure are soot cluster radius of gyration, fractal dimension, number of monomers per cluster, and monomer radius. We have also developed an SLS technique to measure the width of the size distribution.
