Abstract

A method for promoting a boiling heat transfer by applying an electric field to a heat exchange medium, comprises making the relaxation time of an electric charge of a heat exchange medium used equal to or smaller than the characteristic time with respect to motion of bubbles generated by the heat transfer surface in the heat exchange medium to maximize the maximum boiling heat flux.
