Abstract
AbstractParticle sizing by light scattering and electronmicrographing in sooting premixed low pressure hydrocarbon (propane, ethine, benzene) oxygen flames has been investigated. Particle size distributions resulting from electronmicrographs can be simulated by the limiting cases of self‐preserving distributions. When these distributions are used for evaluation of light scattering measurements good agreement is observed between particle sizes obtained by light scattering and by electronmicrographs. Indications to a correlation of the optical properties of soot particles with their age are obtained from particle size moments and both scattering and extinction measurements. This correlation for the refractive index can qualitatively be explained by means of the dispersion model due to structural changes of the soot particles.
