Bubbly and buoyant particle–laden turbulent flows

V Mathai, D Lohse, C Sun - Annual Review of Condensed Matter …, 2020 - annualreviews.org
Fluid turbulence is commonly associated with stronger drag, greater heat transfer, and more
efficient mixing than in laminar flows. In many natural and industrial settings, turbulent liquid …

Bubble Formation and Motion in Liquids—A Review

D Kosior, A Wiertel-Pochopien, PB Kowalczuk… - Minerals, 2023 - mdpi.com
In flotation, a bubble acts as a carrier for attached particles. The properties of the gas–liquid
interface of the bubble are one of the main factors determining the bubble motion and …

Deep learning-based automated and universal bubble detection and mask extraction in complex two-phase flows

Y Kim, H Park - Scientific reports, 2021 - nature.com
While investigating multiphase flows experimentally, the spatiotemporal variation in the
interfacial shape between different phases must be measured to analyze the transport …

Analysis and modelling of Reynolds stresses in turbulent bubbly up-flows from direct numerical simulations

A Du Cluzeau, G Bois, A Toutant - Journal of Fluid Mechanics, 2019 - cambridge.org
Two-phase bubbly flows are found in many industrial applications. These flows involve
complex local phenomena that are still poorly understood. For instance, two-phase …

The interfacial modes and modal causality in a dispersed bubbly turbulent flow

Y Liu, W Wang, G Yang, H Nemati, X Chu - Physics of Fluids, 2023 - pubs.aip.org
While data-driven analysis has demonstrated significant success in single-phase flow
systems, its application to multi-phase flows has been relatively limited with fewer examples …

Thin disks falling in air

A Tinklenberg, M Guala, F Coletti - Journal of Fluid Mechanics, 2023 - cambridge.org
