摘要：

Soot particle sizing and number density measurement by laser light scattering have been reformulated to take into account nonspherical shape effects. By assuming a morphology consisting of chains of monomer spheroids, and the concepts of fractal theory, it has been possible to determine the structural parameters of such clusters from extinction and multiangle scattering measurements. This permits more realistic calculations of soot particle radiative properties and puts soot sizing/number density measurements on a better basis. Experiments performed in and ethylene-air slot burner yield credible cluster parameters using this approach.
