Study on Permeability of Ice/Water Mixtures
Abstract
The purpose of the research was to study how the permeability of porous ice/water mixtures changes during storage under controlled conditions, and how those changes vary with difference in types of ice particles. Also, difference in stickiness between various kinds of ice particle was examined. Experiments were carried out on mixtures of water with sliced ice, semispherical ice particles and frazil ice, and the permeability of the samples were measured before and after storage in a tank where the samples were kept at 0°C. No channeling effect was observed. The permeability of the sliced ice and compressed frazil ice increased during 24 hours of storage. On the other hand, the semispherical ice had no change. Almost all types of ice particle stick to one another by storing. Exception was observed on frazil ice. Frazil ice tends to stick to one another with the same crystal direction at the early stage, but later on there was no distinguishable difference in sticking behavior with others. It was concluded that clustering of particles in the porous mixtures into bigger size, and transformation of sharp edges on the particles into smoother surfaces caused the increase in permeability.
