EHD Effects on Pool Boiling

Characteristics of heat transfer and hydrodynamics of boiling of liquid nitrogen on the surfaces with different types of non-uniformities at the presence of external electric fields are experimentally investigated. It is shown that the formation of field traps is a major mechanism of heat transfer enhancement. And this effect result in noticeable change of two-phase hydrodynamics in vicinity of heated surface.

An experimental study of the action of an intense electric field on the pool boiling of n-pentane is presented. By the application of a 25 kV/cm electric field strength, a threefold heat transfer enhancement is obtained. The effect of the electric field polarity has been researched. In ...

This article deals with an experimental study of the in uence of a DC uniform electric eld on the nucleate boiling heat transfer. Electrohydrodynamic (EHD) effects on heat transfer coef cients for dielectric liquids are quantitatively investigated by performing experiments on various ...
