In order to clarify phenomena such as the solidification of soil containing seawater in the ground freezing technique, a horizontal copper cylinder was set in a porous medium saturated with an aqueous solution, and the porous medium, whose size was sufficiently large compared with the cylinder, was solidified by cooling the cylinder. Such a solidification process with natural convection caused by the temperature and concentration gradients in the liquid and mushy regions was studied analytically and experimentally. From the comparison of the analytical results with the experimental ones, the present analysis was found to be useful to simulate this solidification process. By the analysis, the characteristic of the solidification process, especially, the influence of grain size of the porous medium on the solidification phenomenon, was clarified.
