Size Distribution and Mean Diameter of Microbubbles in Different Types of Ejector Bubble Generators [PDF]
This study investigates the influence of air discharge on bubble size distribution across various types of bubble generators. Air discharge rates were adjusted between 0.1 lpm and 1.0 lpm for ejector, ejector-barrier plate, and venturi bubble generators,

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

On the reliability of an optical fibre probe in bubble column under industrial relevant operating conditions [PDF]
When bubble columns are operated under industrial relevant conditions (high gas and liquid flow rates, large bubbles and vortices,. . .), local data, and especially bubble size values, are difficult to obtain.

Bubble growth in a two-dimensional viscoelastic foam [PDF]
The effects of viscoelasticity on the expansion of gas bubbles arranged in a hexagonal array in a polymeric fluid are investigated. The expansion is driven by the diffusion of a soluble gas from the liquid phase, and the rate of expansion is controlled ...

Hydrodynamics, acoustics and scaling of traveling bubble cavitation [PDF]
Recent observations of the geometries of growing and collapsing bubbles over axisymmetric headforms have revealed the complexity of the "microfluidmechanics" associated with these flows (Hamilton et al., 1982, Briancon Marjollet and Franc, 1990, Ceccio ...

Influence of liquid surface tension (surfactants) on bubble formation at rigid and flexible orifices [PDF]
The influence of liquid surface tension on the bubble formation from both rigid and flexible orifice has been investigated. The liquid phases under test are aqueous solutions with butanol or surfactants (cationic, non-ionic and anionic); static and ...
