RISDiscontinuities in the Orkiszewski Correlation for Predicting Pressure Gradients in Wells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Orkiszewski correlation is used extensively in the petroleum industry for predicting pressure gradients when gas and liquid flow simultaneously in wells. Unfortunately, the correlation contains ...
Pressure Drop Correlations for Inclined Two-Phase Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure drop behavior in two-phase inclined flow was studied. For bubble and slug flow, a no-slip friction factor calculated from the Moody diagram was found adequate for friction head loss ...
Two-Phase Flow in Piping Components
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-phase and single-phase pressure drop data were obtained for flow in horizontal 5.08-cm-dia pipe and piping components that included: a 9.14-m straight section of pipe; a gate valve; an ...
Predicting Compositional Two-Phase Flow Behavior in Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computational algorithm for predicting pressure and temperature profiles for compositional two-phase flow in pipelines has been developed. The algorithm is based on the coupling of the momentum ...
Prediction of Annulus Pressure Gradients in Pumping Wells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental data on pressure gradients were obtained for gas bubbling through static liquids in various concentric annulus configurations with eight different liquids. Although a definite liquid ...
Upward Vertical Two-Phase Flow Through an Annulus—Part II: Modeling Bubble, Slug, and Annular Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mechanistic models have been developed for each of the existing two-phase flow patterns in an annulus, namely bubble flow, dispersed bubble flow, slug flow, and annular flow. These models are ...
Experimental Study of Two-Phase Normal Slug Flow in a Pipeline-Riser Pipe System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Slug flow was studied with air-kerosene flow in a 2-in. pipeline-riser pipe system consisting of a 100-ft pipeline and a 50-ft vertical riser. Pipeline inclinations of ± 5 deg, −2 deg, ...
Experimental Study of Oil-Water Flow in Inclined Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure loss and water holdup data were measured for oil-water flow in 1.5-in-dia inclined pipe with inclination angles from ± 30 deg to ± 90 deg from horizontal. Pressure losses ...
Upward Vertical Two-Phase Flow Through an Annulus—Part I: Single-Phase Friction Factor, Taylor Bubble Rise Velocity, and Flow Pattern Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Upward gas-liquid flow through vertical concentric and fully eccentric annuli was studied both experimentally and theoretically. A flow system was designed and constructed for this study. The ...
Simulation of Transient Two-Phase Flow in Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The laws of conservation of mass and linear momentum were applied to a two-phase mixture to formulate a mathematical model which simulates isothermal, transient two-phase flow of gas and liquid ...
