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

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