| Abstract: | The conjugate problem on heat transfer in a system of subsurface channel one-duct heat pipeline-environment is solved by the finite element method. Thermal regimes of the heat pipeline are analyzed, depending on the temperature at the internal boundary of the system. Values of the main characteristics of the system are found and adequacy of the proposed model is validated. |
