要約

This paper deals with the freezing characteristics of supercooled water on an oscillating cold surface. The supercooling of liquid is easily released by adding some activation factors but the mechanism of freezing of supercooled liquid under the activation conditions has not been made clear. In our previous paper, the authors discussed the effect of free surface deformation on the freezing of supercooled liquid droplets. Following the previous paper, the effect of oscillation in the meniscus between the free surface of supercooled water and cold container wall was experimentally examined. The results clearly showed that the relative velocity between the falling water film near the concave meniscus and the oscillating cold surface affects on the degree of supercooling. Namely, the degree of supercooling decreases with the frequency of wall oscillation, except for a certain frequency, at which the falling of water film is synchronized with the downward motion of the cold surface.
