For the utilization of the waste hot water, advanced condensers with a higher performance have been studied by applying non-uniform electric fields. In this report, the condensation outside a vertical tube has been experimentally augmented by use of helical wire electrodes. Consequently, by extracting the condensate electro-hydro-dynamically from the condensation surface to the helical wires, 96% of the total amount of the condensate could be removed from the tube, and the heat transfer coefficients have been increased over 2.8 times compared with the one without electric fields. The relation between the removed condensate amount and heat transfer augmentation value was explained quantitatively by considering the decrease of the film thickness due to condensate removal under the condition of laminar falling film flow.
