The mathematical models of a multicomponent gas mixture transmission on the shelf of the Northern Seas in different regimes are presented. Behavior regularities of the pressure, velocity and temperature along the pipeline route in the hyper-pressure range are investigated. The resulting conclusions are illustrated by the diagrams of these value distributions, which were constructed from calculations using presented model. Influence of inlet temperature on the acceptable pressure value is investigated. The factors influencing the efficiency of the sea gas-pipeline are discussed. Refs 4. Figs 4.
Keywords: gas-pipelines, hyper-pressure, mathematical models, the behavioral characteristics of velocity, of temperature and of density of thermodynamic model, the influence of heat exchange processes.
