New Dimensionless Correlations for the Evaluation of the Thermal Resistances of a District Heating Twin Pipe System [PDF]
Applied Sciences, 2021 The heat losses from pre-insulated double-pipe district heating (DH) systems buried in a homogeneous soil are studied numerically. The study is conducted using the diameter of the pipes and their distance, the size of the insulation, the thermal conductivity ratio between the insulation and the soil, as well as the burial depth of the double-pipe ...
