RISThe Study of Dynamic Slug Flow Characteristics Using Digital Image Analysis—Part II: Modeling Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A definition is given for a Froude number in the liquid film ahead of the slug and it is seen that slug characteristics are strongly influenced by the Froude number. The mechanisms in the ...
The Study of Dynamic Slug Flow Characteristics Using Digital Image Analysis—Part I: Flow Visualization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports the application of novel, digital image analysis techniques in the study of slug flow characteristics, under dynamic conditions in two-phase gas-liquid mixtures. Water and an ...
The Flow of Slugs in Horizontal, Two-Phase Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow characteristics in horizontal slug flow are studied experimentally in the Harwell Laboratory 150-mm-dia pipeline. If a frame of reference is taken as moving with the translational ...
Liquid Holdup in Large-Diameter Horizontal Multiphase Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper studies the liquid holdup within the mixing zone of the slug. The results of the study show that the liquid holdup begins at the liquid holdup of the liquid film before the slug ...
Effect of Drag-Reducing Agent on Slug Characteristics in Multiphase Flow in Inclined Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of drag-reducing agent (DRA) on multiphase flow in upward and downward inclined pipes has been studied. The effect of DRA on pressure drop and slug characteristics such as slug ...
Oil-Water Two-Phase Flows in Large-Diameter Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-phase oil-water flows in a 10-cm-dia horizontal pipe have been experimentally investigated to study the effect of surfactant on oil-water distributions. Results show that at input water cut ...
Investigation of Flow Regime Transitions in Large-Diameter Inclined Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multiphase oil/water/gas flow regime transition studies are carried out in a 10-cm i.d., 18-m long pipe at inclinations of ±2 deg at system pressures between 0 to 0.79 MPa. The results ...
Studying Transient Multi-Phase Flow Using the Pipeline Analysis Code (PLAC)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Pipeline Analysis Code, PLAC, is utilized to study the flow generated from a shallow dip in a long pipeline. It shows that much longer and infrequent slugs are formed when liquid is ...
Effect of Drag-Reducing Agents in Multiphase Flow Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of drag-reducing agents (DRA) on pressure gradient and flow regime has been studied in horizontal and 2-deg upward inclined pipes. Experiments were conducted for different flow regimes ...
Mass Transfer Coefficient Measurement in Water/Oil/Gas Multiphase Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mass transfer studies in oil-containing multiphase flow provide fundamental knowledge towards the understanding of hydrodynamics and the subsequent effect on corrosion in pipelines. Mass transfer ...
