RISSensitivity of Slug Flow Mechanistic Models on Slug Length
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Slug flow is one of the common flow patterns in gas and oil production and transportation. One of the closure relationships required by the multiphase flow mechanistic models is slug length ...
Unified Model for Gas-Liquid Pipe Flow via Slug Dynamics—Part 1: Model Development
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A unified hydrodynamic model is developed for predictions of flow pattern transitions, pressure gradient, liquid holdup and slug characteristics in gas-liquid pipe flow at all inclination angles ...
Unified Model for Gas-Liquid Pipe Flow via Slug Dynamics—Part 2: Model Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In Zhang et al. [1], a unified hydrodynamic model is developed for prediction of gas-liquid (co-current) pipe flow behavior based on slug dynamics. In this study, the new model is validated ...
Observations of Slug Dissipation in Downward Flow
Publisher: The American Society of Mechanical Engineers (ASME)
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, ...
Pressure Loss/Gain Boundary of Gas-Liquid Downward Flow in Inclined and Vertical Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Investigation of Paraffin Deposition During Multiphase Flow in Pipelines and Wellbores—Part 1: Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Results are presented from two-phase flow wax deposition tests using a state-of-the-art, high-pressure, multiphase flow test facility. Wax deposition was found to be flow pattern specific and ...
Experimental Study of Low Liquid Loading Gas-Liquid Flow in Near-Horizontal Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Slug Dynamics in Gas-Liquid Pipe Flow
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Investigation of Paraffin Deposition During Multiphase Flow in Pipelines and Wellbores—Part 2: Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A Joint Industry Project to investigate paraffin deposition in multiphase flowlines and wellbores was initiated at The University of Tulsa in May 1995. As part of this JIP, a computer program, ...
Modeling of Slug Dissipation and Generation in Gas-Liquid Hilly-Terrain Pipe Flow
Publisher: The American Society of Mechanical Engineers (ASME)
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. ...
