Three kinds of beads - vinyl chloride, glass and steel beads - with different mean diameters were each packed in a rectangular cell. These packed beads were saturated with NaCl-solution and used as porous media. The solidification process where the porous medium was solidified from one vertical wall of the cell, was investigated experimentally and analytically. In the analysis, the permeability in a mushy region, which was considered to be one of the main factors governing the above solidification process, was experessed as the n-th power function of the volume fraction of the liquid phase in the mushy region. By discussing the results of the distributions of temperature, concentration and the volume fraction of the liquid phase and the results of streamline contours, the influences of the initial concentration of the solution and the mean diameter of beads on the present solidification process were clarified.
