Fuel Effects on Soot Formation in Turbojet Engines.
Abstract
The sooting tendencies of sixteen Navy jet fuels and eight fuel blending components have been studied in laboratory flames to compare with results obtained in other programs using these fuels in turbojet engines and combustors. The average molecular weight, density, ASTM smoke point, and diffusion flame and premixed flame threshold sooting index of each fuel have been measured. An apparatus has been assembled to measure premixed flame soot yields using a multi-wavelength laser extinction technique. Experiments have been performed on a six-component test fuel blended using pure hydrocarbon components. The diffusion flame soot threshold of this fuel can be predicted using the pure component values but the predicted premixed flame soot threshold is larger than measured. Experiments are planned to measure soot yields of the jet fuels and to correlate the laboratory measurements with engine test results. (Author)
