Experiments and modelling of a draft tube airlift reactor operated at high gas throughputs [PDF]

open access: yes, 2013
One-dimensional modelling of global hydrodynamics and mass transfer is developed for an annulus sparged draft tube airlift reactor operating at high gas throughputs.

Bubble Characteristics in Multi-Phase Flow Systems: Bubble Sizes and Size Distributions.

open access: yesJOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1997
The bubble characteristics for multi-phase flow systems were studied in a two-dimensional column by direct visual observation together with the image processing of photographs. The effects of operating conditions such as particle sizes, superficial gas and liquid velocities on bubble flow behavior were examined.

Size Distribution and Mean Diameter of Microbubbles in Different Types of Ejector Bubble Generators [PDF]

open access: yesJournal of Applied Fluid Mechanics
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,

Application of the double optic probe technique to distorted tumbling bubbles in aqueous or organic liquid [PDF]

open access: yes, 2005
The optic probe technique is widely used to investigate bubble reactors. To derive values of bubble local velocities and bubble local sizes, a specific signal treatment is usually applied under severe assumptions for bubble path and shape.

Bubble statistics and coarsening dynamics for quasi-two dimensional foams with increasing liquid content [PDF]

open access: yes, 2013
We report on the statistics of bubble size, topology, and shape and on their role in the coarsening dynamics for foams consisting of bubbles compressed between two parallel plates.

Analysis of the characteristic lengths in the bubble and slug flow regimes generated in a capillary T-junction [PDF]

open access: yes, 2016
We present an analysis of the geometry of the continuous and disperse phases in the bubble and slug flow regimes in air–water mixtures generated in a capillary T-junction of 1 mm internal diameter.

Preliminary numerical study of single bubble dynamics in swirl flow using volume of fluid method

open access: yesNuclear Engineering and Technology, 2021
Spacer grid with mixing vane had been widely used in nuclear reactor core. One of the main feather of spacer grid with mixing vane was that strong swirl flow was formed after the spacer grid.

Stages of steady diffusion growth of a gas bubble in strongly supersaturated gas-liquid solution

open access: yes, 2009
Gas bubble growth as a result of diffusion flux of dissolved gas molecules from the surrounding supersaturated solution to the bubble surface is studied. The condition of the flux steadiness is revealed.

Bubble Lift-off Size in Forced Convective Subcooled Boiling Flow [PDF]

open access: yes, 2005
Forced convective subcooled boiling flow experiments were conducted in a BWR-scaled vertical upward annular channel. Water was used as the testing fluid, and the tests were performed at atmospheric pressure.
