Investigation of jet fuel thermal stability using photon correlation spectroscopy and a quartz crystal microbalance
- Sandia National Labs., Albuquerque, NM (United States)
In order to provide input for the development of predictive models of jet fuel degradation and deposition of solids, an experimental assembly for integrated photon correlation spectroscopy (PCS) and quartz crystal microbalance (QCM) measurements on heated fuels has been designed and tested. PCS provides in situ, real-time monitoring of particle formation in the liquid while the microbalance system yields complementary measurements of mass desposited on a surface. Materials examined include Jet A POSF-2827, a non-hydro-treated fuel, and Jet A POSF-2747 (high hydro-treated). POSF-2827 rapidly generates large numbers of submicron-diameter particles at modest temperatures (T=130-150{degrees}C). After a few hours, this process leads to multiple scattering effects that complicate interpretation of PCS data. Mass deposition rates (as measured by the QCM) range from 0.2-0.9 {mu}g-cm{sup -2}-hr{sup -1} over the same temperature range. Lower particle formation and deposition rates are seen with the hydro-treated fuel.
