Crystal Ice Formation and Removal Phenomena at Cooled Liquid Interface

Ice formation phenomena at the interface between cooled liquid and ethylene glycol solution are examined experimentally. It is found that the crystal ice formed at the interface removes from the interface by itself due to buoyancy and drifts away upward the solution, which suggests the possibility of "liquid-like ice" formation by this method. It is shown that the ice growth rate is suppressed with increasing the velocity of solution flow due to the increase of heat transfer from the solution to the interface. It is also shown that the analytical method for ice formation rate proposed in the present study is good to predict the experimental results.
