MOTION OF A GAS–LIQUID MIXTURE IN THE BED–PIPELINE SYSTEM SUBJECT TO HEAT TRANSFER

A model of nonstationary motion of a gas–liquid mixture in a bed–pipeline system, with a new source included in the main line has been constructed taking into account heat transfer between a gas–liquid mixture fl ow in a rising pipe and the medium around the fl ow, and solutions to boundary-value problems are given. In the fi rst approximation, the infl uence of a change in the rheological properties of the gas–liquid mixture with temperature on the dynamics of its motion is determined. Analytical formulas have been obtained making it possible to determine the dynamics of pressure at the bottom of the well and the productivity of the bed depending on the parameters of the system. Numerical calculations are carried out at practical values of the system parameters.
