Js. Ervin et al., THE EFFECTS OF DISSOLVED-OXYGEN CONCENTRATION, FRACTIONAL OXYGEN-CONSUMPTION, AND ADDITIVES ON JP-8 THERMAL-STABILITY, Journal of engineering for gas turbines and power, 119(4), 1997, pp. 822-829
Since dissolved oxygen participates in fuel deposit formation, knowled
ge of the effects of dissolved oxygen concentration on fuel thermal st
ability is critical for fuel system design. In this work, the combined
effects of dissolved oxygen availability and additives on jet fuel th
ermal stability are studied. Experiments with JP-8 jet fuel were condu
cted in a three-part heat exchanger that simulated a complex thermal a
nd flow environment. The dissolved oxygen content at the flow inlet wa
s varied, and deposition was studied under conditions of either fracti
onal or complete oxygen consumption. The effects of a thermal stabilit
y additive package were also studied. An intriguing result found with
JP-8 fuels is an increase in deposits formed in heated regions for dec
reased oxygen consumption, but inverse behavior with the additive pack
age.
