| Summary: | Abstract The paper presents a mathematical model and methodology for conducting thermotechnical calculations of buried multilayer pipelines. A section of the existing oil pipeline running under difficult geological conditions is considered. The methodology for calculating thermal processes and the main results for this section of the pipeline are described, and halos of thawing of permafrost are modeled on the basis of a mathematical model. Modeling was carried out using several options of insulating material with a constant internal diameter of the pipeline and pumping mode. Modeling was carried out in an all-purpose software system of finite element modeling - ANSYS and a TPS module developed by the authors for conducting thermotechnical calculations. |
