Bubble size distribution of foam [PDF]
AUTEX research journal, 2002 A procedure based upon image analysis has been adopted to study the influence of several physical parameters on bubble size in foam. A procedure has been described to account for the distribution of bubble size. Foam was generated in a rotor-stator mixer.

Towards the design of energy-efficient bubble clusters and operation strategies for process control in sonochemical reactors [PDF]
Ultrasonics SonochemistryEnergy efficiency and process control are critical challenges in scaling sonochemical applications. To address this, we introduce a numerical optimisation framework focused on designing pre-seeded bubble clusters driven by impulse ultrasound to minimise ...

Size Distribution and Mean Diameter of Microbubbles in Different Types of Ejector Bubble Generators [PDF]
Journal of Applied Fluid MechanicsThis 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,

Determination of bubble size distributions in bubble columns using LDA
AIChE Journal, 2004 A new method is developed for the determination of bubble size distributions from experimental laser Doppler anemometry (LDA) data through simultaneous measurement of only two orthogonal velocity components and the intermittent time gaps arising out of ...

Mechanism of Microbubbles and Cavitation Effect on Bubble Breakage in a Venturi Bubble Generator [PDF]
Journal of Applied Fluid Mechanics, 2023 Venturi bubble generators have been extensively studied because of having a simple structure and high foaming efficiency, while producing a uniform bubble size.
