A Thermal Analysis for Structures on permafrost
A short review of the complexities in the specification of physical properties for the solution of thermal problems in freezing and thawing soils is presented. The differential equations governing the conduction of heat, in which latent heat is considered as a heat source, are stated. An equivalent...
