Conditions of ascending cocurrent flow in variable-diameter tubes

  • Published:
Chemical and Petroleum Engineering Aims and scope

The working tube of diameter 25.6 mm had terminal portions of smaller diameters (16.8 and 21.4 mm). When a steady film flow is realized in the terminal portions, only unsteady conditions (flooding or unsteady film) are possible in the main middle portion. A diagram of flow modes (falldown, pickup, fluctuating flow, unsteady film flow, steady film flow, etc.) is constructed in phase (water–air) flow rate coordinates. Entrainment boundary, incomplete wetting, and types of wave modes are noted.
