EXPERIMENTAL STUDY AND A MATHEMATICAL MODEL OF THE PROCESSES IN FROZEN SOIL UNDER A RESERVOIR WITH A HOT HEAT-TRANSFER AGENT

On an experimental setup, the authors have measured temperature fi elds in frozen soil during the fi lling of a reservoir with hot heat-transfer agent (oil), and also the change in the shape and position of the front of ice melting (isotherms T = 0^o C) with time. The approximate solution of a two-dimensional Stefan problem on thawing of frozen soil has been given; it has been shown that satisfactory agreement with experimental results can only be obtained with account taken of the convective transfer of heat due to the water motion in the region of thawed soil
