Effects of High Voltage Electrostatic Field on Evaporation of Distilled Water

In this paper the author investigated the effects of the high voltage electrostatic field （HVEF）on the process of the evaporation of the distilled water. The distilled water contained in the beaker was put in the nonuniform HVED，which was made up of a single point pole and a plate pole, the control experiments of water evaporation had been completed under the same condition. The results of experiments show that the rate of the water evaporation in the HVEF is about 1.4 times of the rate of the controls under the experiment conditions. When the distance between the single point pole and the surface of the distilled water is constant, the rate of the vaporization increases nonlinearly with the supplied voltage. When the supplied voltage is not changed, the water vaporization rate is changed with the distance, and the shape of the water vaporization rate curves with the space looks as if the distortion “M”. It shows that there is an optimal distance, and at this optimal distance the evaporation rate is the largest than at another distance. The effects of vaporization under the HVEF are the linear superposition of the vaporizing effects in non-electric field and of the vaporizing effects in only having the electric field.
