초록

Freezing of the pure water saturating a packed bed of spheres in a rectangular cavity is performed experimentally to investigate the effect of bead diameter on the heat transfer rate and temperature vs. time history for the pure water freezing experiments were compared with the freezing of the binary solution(HO-NaCl). Spherical soda-lime glass beads of 2.85mm and 6mm in average diameter constitute the porous medium. The system is cooled through its bottom surface, and the top is maintained at a temperature above the liquids. There was small effect on the temperature distribution in the system of the porosity difference.
