Interfacial area concentration in bubbly flow
Nuclear Engineering and Design, 1990Abstract Interfacial area concentration is one of the most important parameters in two-phase flow. It is related to mass, momentum and energy transfer at the interface. In bubbly flow, it has close relation to bubble diameter. Interfacial area concentration was measured with particular attention to bubble diameter at inlet.

Relating capillary pressure to interfacial areas
Water Resources Research, 2008Experiments were performed on transparent two‐dimensional microfluidic porous systems to investigate the relationships among capillary pressure and the interfacial areas per volume between two fluid phases and one solid phase. Capillary pressures were calculated from the observed interfacial curvature of the wetting‐nonwetting interface, and these ...

The interfacial transfer terms are strongly related to the interfacial area and to the local transfer mechanisms, such as the degree of turbulence near the interfaces and the driving potential. Basically, the interfacial transport of mass, momentum and energy is proportional to the interfacial area concentration and to a driving force.

Interfacial area in liquid‐liquid mixing
AIChE Journal, 1961AbstractIn predicting interfacial area in liquid‐liquid systems there are several published reports which give different results. Differences in methods of measurement of interfacial area and impeller design and location account for some of these discrepancies.For one pair of liquids, 40 parts by volume of ethylhexanol and 60 parts water, it was found ...

INTERFACIAL AREA PRODUCTION AT A TEE JUNCTION
Chemical Engineering Communications, 1992Abstract Kerosene was dispersed in water at a tee junction. The Sauter mean droplet size was determined as a function of flow parameters. It is shown that significant differences exist between this system and others which have been reported. Some of these differences can be attributed to the hypothesis that the system has not achieved dynamic ...

Measurement of large gasndashliquid interfacial areas
The Canadian Journal of Chemical Engineering, 1984AbstractThe light attenuation technique has been modified to expand the range of its applicability up to AL values of 460. This has been accomplished through the use of a laser as the source of monochromatic collimated light, and a very sensitive low‐bias picoammeter.The data obtained using the photographic technique were found to agree reasonably well

Effective interfacial area in a packed column
Chemical Engineering Science, 1968The theory of absorption accompanied by pseudo nth order reaction was used to evaluate values of effective interfacial area, a, as a function of the liquid flow rate in a laboratory packed column. Oxygen was absorbed in aqueous solutions of cuprous chloride and sodium dithionite. Isobutylene was absorbed in an aqueous solution of sulfuric acid.

Nuclear Engineering and Design, 2016
Abstract Wire mesh sensors (WMS) are state of the art devices that allow high resolution (in space and time) measurement of 2D void fraction distribution over a wide range of two-phase flow regimes, from bubbly to annular. Data using WMS have been recorded at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) (Lucas et al., 2010; Beyer et al., 2008 ...

Mass transfer with a change in interfacial area
Chemical Engineering Science, 1962Abstract In this paper the diffusional transport between a free surface and an adjoining medium is studied for cases where there is a flow towards the surface (expansion of the surface) or away from it (contraction0. A distinction is made between the non-steady surface (Section 2) and the steady surface (Section 3).

Interfacial area measurements and surface area quantification for spray absorption
Separation and Purification Technology, 2015Abstract Sprays are widely used in the chemical industry for absorption operations such as gas conditioning and flue gas desulphurization. Despite the wide usage, spray absorption is poorly understood. For absorption applications, the rate of transfer of solute gas into all of the liquid drops is a strong function of the surface area of drops and ...
