| Continual advances in the electronics industry and other high heat-flux fields have led to a need for increased heat transfer efficiency. Spray cooling is one of many methods for removing heat from surfaces. Experimental testing conducted at West Virginia University was sponsored by the Air Force Office of Scientific Research in collaboration with the Air Force Research Laboratory to test the effectiveness of using inductive spray charging to enhance the heat transfer rate. Modifications made to the experimental test rig built by Hunnell (2005) enabled the study of electro-hydro-dynamics.; Experimental testing using working fluids, FC-72 and HFE-7000, was conducted. Electrodes were designed to inductively charge spray droplets (Law, 1978). Research was performed by studying the thermophysics for different spray flow rates ranging from 6 to 10 GPH with a stepwise applied heat load ranging from 0 to 120 W, for an applied electrode voltage between 0 to 6 kV. |
