Abstract
Separate discussions are given of two laser-related in-situ diagnostic techniques pertinent to combustion media species characterization. The first is laser-induced fluorescence for determining the concentrations of selected molecules and/or radicals. The second is Mie scattering of laser radiation for determining the size and concentration of carbonaceous particulates. In discussing laser-induced fluorescence, attention will be given to:applicability criteria; simple two- and multi-level models of radiation interaction; the distinction between linear and saturated fluorescence; difficulties peculiar to combustion media; successful applications of the technique and its limitations. The discussion of Mie scattering will include:distinctions regarding size range, shape and composition of particulates; descriptions of scattering and extinction measurement schemes; the nature and relative importance of global and single particle scattering; problems particular to combustion media; measurement examples and technique limitations.
