Interfacial area transport of vertical upward bubbly two-phase flow in an annulus [PDF]

International Journal of Heat and Mass Transfer, 2003
In relation to the development of the interfacial area transport equation in a subcooled boiling flow, the one-dimensional interfacial area transport equation was evaluated by the data taken in the hydrodynamic separate effect tests without phase change,

Constitutive Modeling of Interfacial Area Transport

2006
The two-fluid model is widely used in the current two-phase flow analysis codes, such as nuclear reactor safety analysis codes RELAP5, TRAC, and CATHARE. In the conventional model, the interfacial area concentration is given by empirical correlations.

Interfacial structures and interfacial area transport in downward two-phase bubbly flow

International Journal of Multiphase Flow, 2004
Abstract An adiabatic, air–water, co-current, vertically downward bubbly flow was studied to gain a better understanding of interfacial structures and flow characteristics. The experimental test sections were round pipes with internal diameters of 25.4 and 50.8 mm.

Distillation tray efficiency and interfacial area

Chemical Engineering Science, 1965
Three pure liquids, viz. water, ethanol and toluene were evaporated in air on a 10 cm dia. sieve plate to ascertain the effect of liquid properties on the mass transfer in the gas phase. It was found that two extreme forms of dispersion exist on the tray, viz.

Development of Research on Interfacial Area Transport

Journal of Nuclear Science and Technology, 2010
Interfacial area concentration and its transport model are quite important in two-fluid model analysis of gas-liquid two-phase flow, which is widely used for the thermal hydraulic analysis of nuclear reactors. Recent developments and the present status of research on interfacial area transport model were reviewed.

Effective interfacial area in irrigated packed columns

Chemical Engineering Science, 1974
Abstract A generalized correlation is proposed for the values of effective interfacial area duing Vaporization, Absorption with and without Chemical Reaction and the values of wetted surface area in terms of dimensionless numbers. The values of effective interfacial area are analysed based on the concept of static and dynamic area, which appears to ...

Measuring Air−Water Interfacial Areas with X-ray Microtomography and Interfacial Partitioning Tracer Tests

Environmental Science & Technology, 2007
Air-water interfacial areas as a function of water saturation were measured for a sandy, natural porous medium using two methods, aqueous-phase interfacial partitioning tracer tests and synchrotron X-ray microtomography. In addition, interfacial areas measured in a prior study with the gas-phase interfacial partitioning tracer-test method for the same ...

Interfacial surface area in dispersions and porous media

Journal of Colloid and Interface Science, 1984
Abstract The structure of a dispersion of interpenetrating spheres (particles or pores), of uniform or of varying sizes, is characterized by its n -particle correlation functions. Such correlations are used to derive the general expression for the interfacial area.
