Solidification around Horizontal Cylinder in Porous Medium Saturated with Aqueous Solution
Abstract
In order to simulate a phenomenon such as a solidification of soil containing sea water 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 large enough 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 simulate well this solidification process. By the results of calculation under various conditions, the characteristic of the solidification process, especially influence of a size of grain of the porous medium on the solidification phenomenon, was clarified.
