Investigation on close-coupled gas atomization for Fe-based amorphous powder production via simulation and industrial trials: Part I. Melt breakup behaviors during primary atomization

open access: yesJournal of Materials Research and Technology, 2023
The primary atomization process is simulated by Volume of Fluid (VOF) model and dynamic adaptive mesh method. The influence of melt mass flow rate and atomization pressure on the breakup process is investigated, and the effect of hot gas atomization is ...

Direct numerical simulations of mass transfer in square microchannels for liquid-liquid slug flow [PDF]

open access: yes, 2008
Microreactors for the development of liquid-liquid processes are promising technologies since they are supposed to offer an enhancement of mass transfer compared to conventional devices due to the increase of the surface/volume ratio.

Hydrodynamics and mass transfer in bubble column: Influence of liquid phase surface tension [PDF]

open access: yes, 2007
According to literature, few experiments are performed in organic solvents which are mostly used in commercial gas–liquid reactors. However, it is commonly accepted that data obtained in aqueous solution allow to predict the surface tension effects, and ...

Numerical investigation of side arm gas volume fraction in two phase T-junction

open access: yesJournal of Mechanical Engineering and Sciences, 2016
T-junction is commonly installed at the offshore production header as a separator to tap produced gas for downstream process operation. A major issue in the T-junction is the liquid carryover, where excessive liquid flows into the downstream process ...

Mass or heat transfer inside a spherical gas bubble at low to moderate Reynolds number [PDF]

open access: yes, 2013
Mass (or heat) transfer inside a spherical gas bubble rising through a stationary liquid is investigated by direct numerical simulation. Simulations were carried out for bubble Reynolds number ranging from 0.1 to 100 and for Péclet numbers ranging from 1
