This article provides a review of the literature devoted to methods of modeling contact heat transfer, as well as the author’s method of numerical modeling and its verification on experimental data. Based on the analysis of the literature, we draw a conclusion about the determining effect of the roughness of the contacting surfaces on the heat exchange between them. We introduce the concept of a digital double of touching surfaces, that is, a model that takes into account their roughness and allows simulating joint mechanical and thermal interaction between contacting bodies. We propose a method of numerical simulation of contact heat transfer, the calculation results of which are in good agreement with experimental data.
Keywords: contact heat transfer, contact thermal resistance, roughness, thermal conductivity, heat flow, cryogenic temperatures, digital surface twin
