Investigation of Water Interactions with Petroleum-Derived and Synthetic Aviation Turbine Fuels
While
undesirable in aviation fuel systems, water is both ubiquitous
and tenacious; thus, interactions between water and aviation turbine
fuel occur regularly. From a fuel user perspective, it is important
to know, understand, and be able to predict such fuel–water
interactions, e.g., water solubility, water settling rate, and interfacial
tension, for proper mitigation. We explore these interactions as well
as surface tension of both petroleum-derived and alternative jet fuels
to compare potential differences between product compositions on these
physical interactions. Observations indicate a positive, nonlinear
correlation between water solubility and both aromatic content and
temperature (from 0 to 50 °C). Water settling rates appear to
follow a Stokes’ law model; therefore, bulk chemical composition
indirectly influences settling rates via density and viscosity. Finally,
surface tension appears positively correlated to sample density, while
interfacial tension is correlated to both surface tension and fuel
aromatic content
