Gas-Liquid Two-Phase Flow Regimes in Microchannels
Heat Transfer, Volume 7, 2002Recent experimental data dealing with gas-liquid two-phase flow regimes and their transitions in microchannels with circular and near-circular cross-sections are reviewed and compared. It is shown that, for microchannels with hydraulic diameters close to 1 mm, the available data are in good agreement.

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

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 ...

Two‐phase, gas‐liquid flows in static mixers
AIChE Journal, 1992This paper reports that static mixers are used for many gas-liquid two-phase operations. some of the typical applications are processing of natural gas to remove hydrogen sulfide or carbon dioxide, waste water treatment, dissolution of gases, hydrogenation, chlorination, and so on.

Two-phase flow characteristics in gas–liquid microreactors
International Journal of Multiphase Flow, 2006Abstract Multiphase chemical microreactors require a detailed knowledge of the flow conditions inside the reaction system. This paper reports flow visualization measurements of the two-phase gas–liquid flow pattern and the liquid velocity distribution inside liquid plugs of an intermittent flow.

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 ...

Two-phase gas-liquid flow in rectangular channels
Chemical Engineering Science, 1984Abstract The results of investigation of hydraulics in a two-phase gas—liquid flow in vertical and horizontal rectangular channels have been presented in the paper. Flow regime maps have been worked out and a method for calculating the pressure drop in a two-phase mixture flow has been proposed. The methods applied in a two-phase flow in pipes have

Optoelectronic Measurements In Two-Phase Gas-Liquid Flow
SPIE Proceedings, 1990An optoelectronic method for measuring the velocity of gas bubble flows in a liquid is presentd in the paper. The results of the investigations were used to verify the Zuber and Findlay model, which has founded a practical application in calculating the void fraction of phases in two-phase flow.© (1990) COPYRIGHT SPIE--The International Society for ...
