Abstract

This paper presents results of an experimental and numerical investigation of soot reducing fuel additive for reducing particulate emissions from aircraft engines. Several soot-reducing additives have been tested in JP-8 at various concentrations in a laminar-flow drop tube furnace. It was found that under enriched oxygen coflow conditions, soot reduction effects could be observed that are similar in some way to those seen in gas turbine engine tests. Metal-containing additives were found to be effective in much smaller quantities than other additives. Ferrocene was the most effective additive tested. Organic additives such as hydrocarbon nitrates and peroxides also showed soot reduction, but required higher concentrations and were less effective than the metal-containing additives. Modeling efforts using JP-8 combustion kinetics, the Method of Moments soot model and kinetics for the organic additive di-tert-butyl peroxide show predicted small soot reductions for 5 % additive in fuel.
