Surface Reactivity of Combustion Generated Soot Particles
Abstract
During the second year of this AASERT program, efforts have remained focused on the further development of the laser-induced incandescence technique and the sampling of soot particles from diffusion flames. Characterization of the laser-induced incandescence technique for soot particle measurements in laminar diffusion flames has been completed. In particular, the relationship between laser fluence and the temporal character of the laser-induced incandescence signal has been carefully examined and documented. Based on this work, the technique is currently being extended to soot particle measurements in turbulent diffusion and droplet flames. Concurrently, efforts have continued on developing a sampling system to collect soot particles from laminar diffusion flames. Several modifications to the sampling system have been made to allow for the collection of sample sizes up to 0.1 gm of soot. A heated burner and vaporizer system have also been developed to allow for the study of liquid hydrocarbon fuels. Of particular interest for the present study is the effect of toluene on soot particle surface reactivity. Samples have recently been obtained in a series of laminar diffusion flames and analysis of the samples is currently underway.
