Fragmentation of bubbles and droplets in turbulence produces a dispersed phase spanning
a broad range of scales, encompassing everything from droplets in nanoemulsions to …

Bubbly flows involve bubbles randomly distributed within a liquid. At large Reynolds
number, they experience an agitation that can combine shear-induced turbulence (SIT) …

High-speed imaging is in popular demand for a broad range of experiments in fluids. It
allows for a detailed visualization of the event under study by acquiring a series of image …

An accurate and fast simulation of large-scale gas/liquid contact apparatusses, such as
bubble columns, is essential for the optimization and further development of many (bio) …

This paper presents a robust image processing technique for bubbly flow measurement over
a wide range of void fractions. The proposed algorithm combines geometrical, optical and …

Budgets of the turbulent kinetic energy from direct numerical simulations (DNSs) of disperse
bubbly channel flows are used to develop a model for bubble-induced turbulence in the …

We report on an investigation of bubble-induced turbulence. Bubbles of a size larger than
the dissipative scale cannot be treated as pointwise inclusions, and generate important …

Abstract An approach for Eulerian–Lagrangian large-eddy simulation of bubble plume
dynamics is presented and its performance evaluated. The main numerical novelties consist …

A quantitative description of the interaction between the turbulence eddies and bubble
groups is crucial for the prediction of the bubble size distribution in bubble columns when …

This work reports an experimental characterisation of the flow properties in a homogeneous
bubble swarm rising at high Reynolds numbers within a homogeneous and isotropic …
