Summary
Through this experimental study, it was found that supercooled water can freeze at less than 100 volts, if direct-current is applied directly to it. There was no deformation of water droplet of spark discharge, as some papers have suggested. It was also found that the probability of freezing depends upon the degree of supercooling, direct-current voltage applied, size of electrode and the distance between two electrods. The mechanism of this effect was discussed and suggested as follows: the high electric field is formed locally due to the existence of surface edge of small projections on the surface. The water molecules having a polarity are drawn near to the cluster on the surface, whose motion is restricted by the existence of electric field. Therefore, embryo can transform to nucleus, instantly.
