Fuels Combustion Research
Abstract
Studies of near and slightly sooting inverse and normal co-flow diffusion flames determined aromatics as the key intermediates to soot formation. The extent of aromatic formation correlated with the earlier Princeton smoke height test results. The effect of oxygen addition to tightly bound fuels (ethene, ethyne and benzene) in diffusion flames was found to accelerate the pyrolysis and thus the soothing tendency, but not to affect other fuels in the temperature range of soot formation. Flow reactor experiments determined oxidation kinetic results for the mono and dialkylated aromatic components of jet fuels. Succinctly, it was found that the alkyl chains are attached initially and in the case of dialkylated compounds not simultaneously. Mechanisms have been presented. Results on boron slurry droplet combustion were obtained and provided a basis for calculating when droplet disruption would occur. Questions with respect to boron cloud combustion addressed mechanisms of ignition and combustion in the regime of chemical kinetic control.
