Calculating soil thermal properties for the purpose of numerical simulation of heat transfer in multi-layered ground profile

Kozłowski T., Kolankowska M., Walaszczyk Ł.

2015

Vol. 7, no. 2

87--94

An example of simulation made by use of a program based on a one-dimensional heat transfer model is presented. Some detailed values and solutions related to soil thermal properties are given, among them, particularly, the freezing point Tf and the unfrozen water content function u(T) are discussed. The results of computation done for multilayered ground profile suggest the occurrence of the “real” depth of frost, as opposed to “conventional” depth of frost, identified with the depth of the zero isotherm.
