Record #113342:

Thermal properties and the nature of freezing soils / Peter J. Williams.

Title: Thermal properties and the nature of freezing soils / Peter J. Williams.
Author(s): Williams, Peter J.
Date: [1991]
Publisher: Fairbanks, AK: University of Alaska Fairbanks
In: Proceedings of the Third International Symposium on Cold Regions Heat Transfer 1991. ([1991]),
Abstract: Invited paper. Temperature changes alter proportions of ice and unfrozen water in frozen soils, and associated latent heat exchange modifies heat capacity greatly. Thermal conductivity is also modified although to lesser degree. Presence of water in frozen soil is ascribable to mineral surface forces and capillarity. Water is mobile and has temperature-dependent potential such that it will tend to move where there are temperature gradients, further modifying thermal behaviour. Recent studies with experimental gas pipeline illustrate these effects and demonstrate unusual nature of thermal properties.
