Effect of Prolonged Electrohydrodynamic (END) Exposure on Aviation Working Fluids.

Abstract

Two aviation working fluids, PAO and FC-72, were exposed to pulsed high voltage for 200 hours in a simulation of electrohydrodynamic heat transfer enhancement. The fluids were analyzed for changes in chemical, physical and electrical properties. The electrode surfaces were also analyzed for any observed buildup. No bulk fluid chemical or physical property changes were observed. There was a change in the electrical properties of PAO, as well as noticeable buildup on the electrode surfaces. This buildup was attributed to electrically induced oxidation reactions. The change in electrical properties could have application of an EHD-enhanced thermal management system are discussed.
