Abstract

In this paper, the influences of electrical field on boiling-condensation heat transfer systems have been investigated using a cylinder heat transfer model. Freon-11 is selected as working fluid. The condensation heat transfer coefficient, the boiling heat flux and the saturation pressure are measured in this investigation. According to the experimental results, it is found that the electric field can influence heat transfer system. The boiling heat transfer is enhanced by the applied voltage, and the saturate vapor of working fluid is condensed on the high voltage electrode directly when the applied voltage is higher than 6 kV. The experimental results have been discussed, and it is considered that the high electrical field strength changes the thermal properties of the working fluid
