Abstract
It is known that the charged water drop in oil with electric field reciprocates between electrode plates. The drop collides repeatedly with each electrode plate. If the drop is in the supercooled state, it initiates to freeze by the collision. In this paper, the effect of the polarity of electrode and its grounding to the initiation are studied experimentally. As a result, it was clarified that neither the polarity nor the grounding influenced the initiation, and the initiation of the drop freezing by colliding with an electrode plate cannot explain according to collision velocity alone.
