The Department of Defense directive 4140.25 dated April 12, 2004 mandates that primary fuel support for land-based air and ground forces in all theaters shall be accomplished using a single kerosene-based fuel, in order of precedence JP-8, commercial jet fuel with additive package, or commercial jet fuel without additives. The objective of the proposed research is to understand those key aspects of combustion of JP-8 that are required to facilitate this conversion. It has been established that an useful approach to understanding combustion of JP-8 is to first develop surrogates that reproduce selected aspects of combustion of JP-8. Experimental, numerical and analytical studies have been carried out. The Aachen surrogate made up of n-decane 80 and trimethylbenzene 20 by liquid volume, and the UCSD surrogate made up of n-dodecane 60, methylcyclohexane 20, and o-xylene 20 by liquid volume were found to best reproduce autoignition and extinction characteristics of JP-8.
