Studies of Scanning Brookfield Viscometry as a Replacement for Freezing Point in Aviation Fuel Specifications.

摘要

This study demonstrated that the viscosity knee temperature measurement correlates very well with measured freezing point and exhibits excellent repeatability. But since the viscosity knee temperature correlates so closely with freezing point, it is unlikely that this new parameter will provide any additional benefit in correlating more closely to fuel flowability and pumpability. This study also provided viscosity limit measurements and analyses yielding viscosity data and maximum limits that can be used to construct a viscosity equivalent limit for current specification fuels. The calculated maximum limits at various low temperatures imply that fuel viscosities are significantly higher than expected when compared to engine OEM operability limits.
