Summary

THE AUTHORS PRESENT THE RESULTS OF AN INVESTIGATION OF HEAT TRANSFER IN FILM VAPOUR CONDENSATION FROM A VAPOUR-GAS MIXTURE ON A VERTICAL PLATE UNDER THE INFLUENCE OF AN ELECTRIC FIELD. WITH A GAS CONCENTRATION IN VAPOUR BELOW 10% A UNIFORM ELECTRIC FIELD SHOULD BE APPLIED, AND AT HIGHER CONCENTRATIONS A CORONA DISCHARGE SHOULD BE USED. THE EFFECTS OF GAS CONCENTRATION IN VAPOUR, OF MEDIUM PRESSURE, TEMPERATURE DIFFERENCE BETWEEN A VAPOUR-GAS MIXTURE AND A WALL, DIFFERENCE OF POTENTIALS, ELECTRIC CURRENT STRENGTH, PHYSICAL PROPERTIES OF A LIQUID PHASE AND OF A VAPOUR-GAS MIXTURE ON THE DEGREE OF HEAT TRANSFER ENHANCEMENT ARE INVESTIGATED. A SEVEN-FOLD INCREASE OF THE RELATIVE HEAT TRANSFER COEFFICIENT IN THE CONDITIONS OF CORONA DISCHARGE EFFECT IS OBTAINED.
