The purpose of this research was to study the change of morphology of ice particle and its effect on permeability of ice/water mixtures as porous media. Various sizes of sliced ice were used and specific area before and after the storage was measured. It was found that the morphology of ice particle changed by storing them for 24 hours in water tank at 0&dge;C. The shape of ice particle seems to change into round and smooth, and specific area decreased. Kozeny's constant was calculated using Kozeny Charmann equation. It was found that the constant decreased and reached to a value for smooth sphere, independent on the porosity and the size of ice particle. Hence, it was concluded that transformation of sharp edges and rough surfaces on the particles into smoother surfaces cause the decrease in specific area and Kozeny's constant, and it leads to increase the permeability.
