Surface Reactivity of Combustion Generated Soot Particles

Abstract

During the first year of this AASERT program, efforts have focused on the development of a sampling probe to extract soot particles from a laminar diffusion flame. Soot samples collected with this system are to be used to study the surface reactivity of the soot particles as a function of position in the flame. A suitable probe system has been developed and tested. Comparisons with laser-based measurements of percent conversion of fuel to soot show reasonable agreement. Additional studies have also been conducted to examine the applicability of laser-induced incandescence (LII) as a soot diagnostic. Results have demonstrated that the LII technique compares very well with previous measurements in a well-studied ethene/air laminar diffusion flame. Measurements of soot volume fraction, particle diameter and number density have been demonstrated.... Soot particles, Surface reactivity, Gas turbines, Diffusion flames, Particle growth.
