Transport of Interfacial Area Concentration in Two-Phase Flow [PDF]

open access: yes, 2012
The accurate prediction of thermal hydraulic behavior of gas-liquid two-phase flow is quite important for the improvement of performance and safety of a nuclear reactor. In order to analyze two-phase flow phenomena, various models such as homogeneous model, slip model, drift flux model and two-fluid model have been proposed. Among these models, the two-

Influence of material transition and interfacial area changes on flow and concentration in electro-osmotic flows [PDF]

open access: yesAnalytica Chimica Acta, 2013
This paper presents a numerical study to investigate the effect of geometrical and material transition on the flow and progression of a sample plug in electrokinetic flows. Three cases were investigated: (a) effect of sudden cross-sectional area change (geometrical transition or mismatch) at the interface, (b) effect of only material transition (i.e ...

Low-concentration tracer tests to measure air-water interfacial area in porous media

open access: yesChemosphere, 2020
The aqueous-based interfacial tracer method employing miscible-displacement tests is one method available for measuring air-water interfacial areas. One potential limitation to the method is the impact of tracer-induced drainage on the system. The objective of this study was to investigate the efficacy of a low-concentration tracer test method for ...
