Abstract
Gas–liquid flow patterns were mathematically modeled in the annular space between two coaxial cylinders, the inner cylinder of which rotates about its axis at a constant speed and the outer cylinder is at rest. The mathematical model was based on the fundamental laws of conservation of mass and momentum. The position of the mobile liquid–gas interface was tracked with the volume-of-fluid method. Two different flow patterns were detected: a stratified flow and a flow in which the gas phase is localized along a helix near the surface of the inner cylinder. The dependences of the dimensional torque on the axial and azimuthal Reynolds numbers were presented.
