Experimental Study of the Oxidation, Ignition, and Soot Formation Characteristics of Jet Fuel
Abstract
The objective of the present research program was to develop a database of kinetic targets, in the form of ignition delay times, for jet fuel representative hydrocarbons, jet fuels, and jet fuel surrogate mixtures, with a focus on gas turbine main combustor conditions (i.e., elevated pressures with air as the oxidizer). Shock tube autoignition studies for 16 hydrocarbons provided quantitative targets for the development of kinetic oxidation models and information regarding the structure-reactivity dependencies for fuel components. Measurements for two jet fuel samples provided real fuel reactivity for a large range of temperatures of interest to gas turbines (650-1200 K at 20 atm) and show that the JP-8 additive package has no discernible influence on fuel reactivity. Studies of two three- and a four-component surrogate mixtures designed to mimic jet fuel reactivity through matching the derived cetane number (DCN) exhibit reactivity very close to that of the jet fuel samples, indicating that there is potential in using DCN to formulate surrogates.
