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.

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.

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 ...

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.

Monitoring system of gas-liquid two-phase flow
Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat. No.04CH37510), 2004A new monitoring system of the flow states of gas-liquid two-phase flow has been developed by using a differential pressure transducer combined with wavelet analysis and fuzzy pattern recognition technique. The differential pressure signal of gas-liquid two-phase flow was obtained under the states of the different flow patterns, including bubble flow ...

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 ...
