Particle Sizing in Combustion Systems, Using Scattered Laser Light

Abstract

Light scattering techniques for particle sizing are reviewed, with emphasis on their use in combustion diagnostics. Submicron soot-particle sizing in flames, using the diffusion-broadened spectrum of scattered light, is discussed in detail, beginning with the pioneering work of S.S. Penner and coworkers. Recent developments in the inversion of scattering data to yield soot number densities and size distributions are then reviewed. Two imaging techniques for measuring particle sizes greater than 1 micro meter are mentioned: a holographic technique and a method using laser light emitted by the particle itself. Keywords: Particle sizing, Light scattering, Holography, Laser doppler spectroscopy.
