A research on gas flow parameters related to pressure drop in a pipeline is conducted. Temperature and pressure distributions along the pipeline are established in accordance with the equations of gas dynamics and the state equation of a real gas with known parameters of incoming gas. Dependence of the mass flow on the known outlet pressure is evaluated. Thermal interaction of the moving gas and the frozen soil is simulated in a conjugate form and thus the real physical process is described more accurately. By means of numerical modeling with the finite elements method various thermal insulation options are examined.
Keywords: gas pipeline, conjugate problem, permafrost, mathematical modeling.
