摘要
This article presents a mathematical model of the shock-free unsteady nonisothermal turbulent flow of a viscous nonideal chemically inert multicomponent gas mix in the offshore circular cross-section gas pipeline with a rigid multilayer coating. The calculations of flow characteristics are given for the problem of the pipeline’s shift to the periodic condition under a periodic change of the consumption rate at the right end. © 2011, Pleiades Publishing, Ltd.
