Abstract

Autoignition JP-8 Low temperature Surrogate
The preignition reactivity behavior of five JP-8 samples, three Jet-A samples, one JP-7 sample, and four JP-8 surrogate mixtures was studied in a pressurized flow reactor in the low and intermediate temperature regime (600-800 K). A strong Negative Temperature Coefficient (NTC) behavior was observed to start near 692 K for all the fuels. No significant differences in the low-temperature oxidation behavior were observed between Jet-A and JP-8, suggesting that the two fuels can be used interchangeably for surrogate development. Two surrogates stood out as the best to mimic the low temperature reactivity of JP-8, the Hex-12 surrogate by Sarofim and coworkers (Eddings et al., 2005 ) and the S1 surrogate by Agosta ( 2002 ). The results showed that extreme care must be taken to ensure that the sample used for surrogate development is of average composition and properties, otherwise severe mistuning of the surrogate could occur.
