- The object of this research is to do quantitative measurements of air bubbles in quasi-two dimensional disk-shaped ice and to analyze it with a theoretical model. Width, length, and area of air bubbles in disk-shaped ice were measured. By comparison of ice-freezing model, air bubble growth model and experimental results, it could be found out that cylindrical bubbles and egg-shaped bubbles are distinguished because of the slope of width decrease. We discovered that different reason for termination of air bubble growth separates cylindrical bubbles and egg-shaped bubbles. We applied it to the theoretical model to make a new model including termination. By this new model, we interpreted the reasons for unique phenomena which occur only in disk-shaped ice. This result can be used to create a more detailed computer graphic model of air bubbles in ice.
