Numerical Analysis on the Effect of Heat Transfer Characteristics and Other Parameters on the Freezing Behavior of Soil in Groundwater Flow

Abstract

On the artificial soil freezing, estimated the completion time and solidification layer thickness are greatly affected by many parameters, such as diameter/pitch of the pipe (s), temperature of the circulating brine, temperature and thermal properties of the soil as well as velocity of groundwater flow. In this paper, we numerically and experimentally examined the effect of these parameters on the freezing of artificial soil. The numerical results were good agreement with experimental ones. It was also shown that the thickness of the solidification layer is considerably influenced by the existence of flow rather than the velocity of flow. But the profile of the layer is still dominated by the velocity and direction of the flow.
