The mechanisms of heat transfer during convective boiling under the influence of AC electric fields

In this investigation the local heat transfer coefficients along the top and bottom of a horizontal tube heat exchanger within which convective boiling of HFE7000 is occurring are measured. Of particular focus is the influence of Electrohydrodynamics (EHD) on the flow regimes and associated heat transfer. To achieve this, thermocouples are embedded into the walls of a transparent sapphire tube coated with a transparent yet electrically …
