Abstract
The theory of filtration heat transfer received the greatest development in connection with the development of geothermal resources. In the problems of mining thermal physics, as a rule, the real collector of the circulation system is replaced by a model. Each calculation scheme contains values characterizing intensity of heat transfer processes. An analysis of theoretical studies and experimental data on heat transfer coefficients and effective thermal conductivity is carried out. Some recommendations are made regarding the application of these coefficients in existing models of filtration heat transfer. Large scatter in the experimental data and lack of clear theoretical dependences indicate the necessity of reasonable choice of coefficients and making calculations for comparative analysis of different heat transfer models.
