Fuels Combustion Research
Abstract
After studying soot formation in normal diffusion flames, near and slightly sooting inverse diffusion flames were investigated to determine the key intermediates to soot formation. The results indirectly confirm that the initial number density of soot particles which form scale with aromatic formation just prior to soot inception. Correlations exist between a fuel's sooting tendency as measured by the Princeton smoke height experiment and the extent of aromatic formation measured in both inverse and normal diffusion flames. Work on the oxidation of the aromatics present in jet propulsion fuels continues with th major effort directed at the dialkylated benzenes. The major study concerned the oxidation of para-xylene. The results indicate oxidation of one side chain at a time before the benzene ring is attached. There is a linear decay of the fuel and the major species detected were toluene, benzene, p-tolualdehyde, p-ethyltoluene and carbon monoxide. Kinetics steps leading to these intermediates are given. Combustion property observations of isolated boron slurry droplets were extended to in-house boron/JP-10 slurries with and without surfactants. The experimental results revealed that stabilizing agents are responsible fo rthe violent disruption of the primary slurry droplet and strongly support the previously proposed hypothesis of the formation of the impermeable shell and subsequent disruption phenomena. Keywords: Born slurry combustion; Boron cloud combustion; Slurry fuels; Jet engine fuels.
