WebTools. In heat transfer, the thermal conductivity of a substance, k, is an intensive property that indicates its ability to conduct heat. For most materials, the amount of heat conducted varies (usually non-linearly) with temperature. [1] Thermal conductivity is often measured with laser flash analysis. Web13.1 Heat Transfer in Soil. In the soil, heat transfer occurs primarily by conduction, although convective heat transfer can be important in some cases. Heat conduction is governed by … WebFeb 16, 2024 · The moisture mass transfer in a state of vapour flow was considered during unidirectional freezing on the example of the conducted laboratory testing. The obtained results have improved understanding of the heat and mass transfer phenomenon during the unidirectional freezing of soils.
