ABSTRACT

The article describes the determination of the temperature field around every line of transit pipeline during transportation of natural gas. Method of elementary balances (counts temperatures in three directions) was used to solve the complex temperature field. On the basis of the analysis, it is possible to determine whether it will be influence and to what extent may be influence of individual gas-pipelines. Formulas for calculations used in these models are specified in this article. The results of each models and simulations are shown in the graphical dependencies. For the analyses were used: Autodesk Inventor Professional, Matlab, Autodesk Simulation Multiphysics.

Keywords: temperature field determination, transit pipeline, natural gas transportation
