Mechanistic Models for Soot Formation

Abstract

One percent toluene in argon in a single pulse shock tube coupled to a new GC/MSD analytical system. Many high molecular weight species were identified and this information is being used to examine and compare PAH formation mechanisms. Ring formation mechanisms during the oxidative pyrolysis of methane were compared and the dominant pathway was found to be recombination of propargyl radicals. Using an appropriately simplified reaction set, benzene profiles were predicted for the case of an opposed-jet, methane-air diffusion flame. A soot model was updated to include effects from particle aging. A band radiation model was developed to treat radiation from flames with varying degrees of optical thickness. This code was used to model the effects of radiation from gas-phase species in a flame but can be extended to the case of particle radiation.
