Abstract
Enhancement of natural-convection boiling heat transfer by electric field is investigated experimentally. Boiling of refrigerant water occurs on an aluminum rod and platinum sphere under the atmospheric pressure, and a D.C. voltage up to 660V is applied between the heat transfer surface and an electrode made of stainless-steel wire-mesh 10 mm apart. The whole boiling curve is measured under different applied voltages. The results of experiment indicate that boiling heat transfer is enhanced by electric field. An enhancement ratio of film boiling heat transfer as high as 9 times is obtained. As a result, confirmed the effect of EHD on boiling heat transfer.
