Applications of Laser Scattering Probes to Turbulent Diffusion Flames

Abstract

The objective of this work is to determine flame properties useful for the advancement of combustion system modeling procedures and design aids, particularly in areas related to the interactions between flame turbulence properties and high temperature combustion chemistry. Toward this goal, measurements have been made of flame structure important for understanding and verifying the basic assumptions upon which the models are based. Thus, we have used spontaneous Raman scattering to determine average and excursion values of the flame front and the viscous superlayer for a co-flowing jet turbulent diffusion flame, and planar laser-induced fluorescence to provide two- dimensional instantaneous images of the flame reaction zones themselves over a range of Reynolds numbers.
