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 ...

Characterization of Bubble Size Distributions within a Bubble Column [PDF]
Fluids, 2018 The current study experimentally examines bubble size distribution (BSD) within a bubble column and the associated characteristic length scales. Air was injected into a column of water via a single injection tube. The column diameter (63–102 mm), injection tube diameter (0.8–1.6 mm) and superficial gas velocity (1.4–55 mm/s) were varied. Large samples (

In situ measurements of void fractions and bubble size distributions in bubble curtains
Experiments in Fluids, 2023 AbstractWe report the development of a novel measurement system designed to measure bubble properties in bubble curtains (i.e. planar bubble plumes) in situ alongside acoustical measurements. Our approach is based on electrical, contact-based needle sensors in combination with an optical system.

Inversion of Volume Scattering Function for Estimation of Bubble Size Distribution in Ocean Waters
IEEE Access, 2021 Angular distribution of the intensity of light scattered by a spherical air bubble in the oceanic medium is distinctive near the critical scattering angle region, when light interacts with a bubble with a refractive index less than its surrounding medium.
