Abstract
A freezing of a porous medium saturated with an aqueous solution is such a complex phenomenon where the freezing progresses with interaction of effects of a permiability in a mushy region, mass diffusion and a double-diffusive convection. In this report, a simple transient measurement method of a permeability in a mushy region offered by authors to investigate physical parameters on which the permeability depends, and the measurement results are stated. Then, the results of experiments and analyses for two types of models of the freezing which have been done by authors are stated.
