Calculation of the Head Loss in a Kerosene–Air Flow Upon Change in the Two-Phase-Flow Structure on an Inclined Portion of a Pipeline

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

A procedure for calculating of the head loss in two-phase flow on an inclined portion of a pipeline has been described and substantiated. The developed procedure is applicable to two-phase flows characterized by a very low mass gas content (x ~ 10–4) butan appreciable flow-rate volume gas content (α ~ 0.1–0.5). A computational scheme for the coordinate of change of regimes has been proposed on the basis of the available experimental material. A relation for calculation of the change in the pressure on the pipeline′s inclined part has been presented that accounts for the friction loss and for the change in the kinetic energy of the flow in the process of change of regimes.
