Gas-Liquid Two-Phase Flow in Pipelines
SPE Annual Technical Conference and Exhibition, 1990ABSTRACT A combined theoretical and experimental investigation to study the behaviour and characteristics of gas-liquid two-phase flow in horizontal pipelines is described in this paper. A simple theoretical model was developed to provide predictions of liquid hold-up in equilibrium stratified two-phase flow regimes and ...

Pipes Conveying Gas–Liquid Two-Phase Flow
2020In this chapter, the dynamic behavior of pipes conveying gas–liquid two-phase flow is analytically and numerically investigated on the basis of the generalized integral transform technique (GITT). The use of the GITT approach in the analysis of the transverse vibration equation leads to a coupled system of second-order differential equations in ...

Photography of Two-Phase Gas/Liquid Flow
The Journal of Photographic Science, 1964AbstractThis paper describes the ways in which photographic methods have been used in the Harwell studies of two-phose (gas/liquid) flow.

Gas/Liquid Two‐Phase Flow under Low Gravity Conditions
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2001AbstractA novel flow pattern map is developed based on five dimensionless parameters. The transition region from dispersed bubble to slug flow, from slug to frothy slug/annular flow and from frothy slug/annular to annular flow is presented and good agreement between theory and experimental data from the literature is obtained.

Two-phase gas–liquid flow in horizontal corrugated channels
International Journal of Multiphase Flow, 2000Abstract Experiments have been carried out for adiabatic concurrent gas–liquid flow of nitrogen and water through two corrugated test sections. This study examines flow patterns as the gas fluxes are increased. At low gas fluxes two main patterns have been observed: stratified flow for low liquid fluxes and bubble flow for greater ones. The mean wall

Chromatographic sample collection from two-phase (gas+liquid) flows
Journal of Chromatography A, 2011A particularly challenging sample presentation in analytical chemistry is a flowing stream that consists of both a gas and liquid phase, combined with the common situation in which a reliable analysis is needed for both phases, separately. In these cases, the vapor and liquid must be physically separated (without change to either), before the ...

1998
Flow and heat transfer enhancement due to an electromagnetic field (EMF) and pulses (EMP) on single and two phase fluid flow in a heat exchanging system has increased in importance as a result of recent developments in high power transformers and transmission line cable cooling systems (Chang and Watson 1994). In the boiling water and pressurized water

Gas-liquid contacting in vertical two-phase flow
Industrial & Engineering Chemistry Process Design and Development, 1985Deep shaft reactors (DSR's) employ vertical two-phase bubbleflow to effect mass transfer between gases and liquids. Mass transfer coefficients in these devices are high, and the large pressures at the base of the reactor serve to promote gas dissolution.

Drag Reduction in Two‐phase Gas‐Liquid flow
Developments in Chemical Engineering and Mineral Processing, 1996AbstractDrag reduction is reported for two phase air water liquid co‐current flow for three different pipe diameters (0.0454, 0.0508, 0.0935 m). The drag reduction was achieved without the addition of drag reducing agents such as surfactants. Drag reduction compared to single phase gas flow occurred in the stratified and the stratified plus ripple ...
