Absorption in a three-phase fluidized bed II: Mass transfer investigations [PDF]

Hemijska Industrija, 2003
The absorption of carbon dioxide in aqueous diethanolamine solutions was carried out in a three-phase fluidized bed with inert spherical packing. The rate of absorption was calculated on the basis of measuring the concentration change in the liquid phase

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

, 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]

Analytica 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 ...
