Description

In modern aircraft, the onboard fuel is used as a coolant or thermal management fluid.  The ability of jet fuels to handle the imposed thermal stress without generating harmful coke deposits is a key enabler for advanced aviation technologies.  This research opportunity is focused on research into the chemical and physical processes that occur in jet fuels at elevated temperatures and pressures.  Of particular interest are the chemistry and physics associated with formation of deposits, and in the development of instrumentation and methods to investigate and model these processes.
