Investigations of the influence of electric fields on the process of condensations were aimed, mainly, on clarifying the physical mechanisms of the electric field effect on the condensation. This paper deals with the investigation of condensation under the influence of electric currents. Experiments were carried out on the installation consisting of an external cooled cylindrical electrode used as a heat receiving element, and an internal electrode connected to the high voltage power supply. The vapor or vapor-air mixture condensed on the external electrode. When the internal surface of the external cylinder is thoroughly washed and polished, and the surface of the rod electrode is well insulated (with lacquer) then in the interelectrode gap an electric field exists while the current is almost zero (within the bounds of precision of the measurements). In these conditions the electric field did not effect significantly (no more than a few percent) the process of the heat and mass transfer. A similar situation was observed when the surface of the rod electrode was polished and both the electric field and current existed in the interelectrode gap. The observed weak effects could be explained by the electric field influence. However, the observed interaction of the field and medium changes significantly when the wire insulation is perforated. In this case both the electric field and current exist in the interelectrode gap; however, in contrast to the previous case, a substantial enhancing of the heat and mass transfer takes place. The explanation is as follows: the perforations acts as corona regions, that is as sources of corona discharge, which are effective “suppliers” of space free charges ( ρ ≠ 0) which give rise to the electric wind phenomenon. Both these properties are very favorable for the intensification of the heat and mass transfer.figureThe dependence of the relative mass of condensed water on the current intensity and blow-off flow rate: 1 – 1.3; 2 – 2.0; 3–3.5m/s (air concentration is 5%).Condensation of the vapor-air mixture took place on a cooled surface of the external armature of the cylindrical capacitor with its diameter of 28 mm under the influence of corona discharge on the rod electrode (with its diameter of 2 mm) with the perforated isolation. The characteristic results are presented as graphical dependencies of the relative mass of condensed water 0 / E G G and the relative coefficient of the heat transfer as a function of the concentration of air in the vapor-air mixture, current intensity I (see the figure), blow-off flow rate and other parameters. The physical interpretation of the obtained experimental data from the point of view of the corona discharge influence is presented. On the basis of the molecular-kinetic principles it is shown that the corona discharge plays a diverse role in the process of condensation: it increases the number of condensation nuclei due to emerging ions; reduce their mobility due to the formation of solvate structures and enhancement of the effect of the electric wind; charges the medium causing its total mixing; and destroys the condensate film. These factors lead to a significant intensification of the process of heat and mass transfer during condensation in the electric field. This effect can be used in many technologies and devices.
