Abstract: Detailed observations were made for slug flow in an upward to downward pipeline configuration with 13 capacitance sensors. The results presented in this study are based on four typical tests, ...

Abstract: Gas-liquid downward flow is frequently encountered in hilly-terrain pipelines, downcomer pipes extending from offshore production platforms to sea floors, and steam injection wells in thermal ...

Abstract: Gas-liquid two-phase flow exists extensively in the transportation of hydrocarbon fluids. A more precise prediction of liquid holdup in near-horizontal, wet-gas pipelines is needed in order to ...

Abstract: The continuity and momentum equations for fully developed and spatially developing slug flows are established by considering the entire film zone as the control volume. They are used for the ...

Abstract: Hilly-terrain pipelines consist of interconnected horizontal, uphill and downhill sections. Slug flow experiences a transition from one state to another as the pipe inclination angle changes. ...
