Variables of hydrodynamics are equally important as those of surface chemistry in
determining the efficiency of froth flotation processes. In a mechanical flotation cell, macro …

While multiphase flows are abundant in both natural environments and engineering
applications, their analysis and quantification present challenges. In particular …

The aggregation attachment efficiency (α) is the fraction of particle–particle collisions
resulting in aggregation. Despite significant research, α predictions have not accounted for …

Positron emission particle tracking (PEPT) enables 3D localization and tracking of single
positron-emitting radiolabelled particles with high spatiotemporal resolution. The translation …

Positron Emission Particle Tracking (PEPT) is a technique which allows the three-
dimensional, internal dynamics of opaque systems to be imaged with high temporal and …

Impellers play a key role in flotation cells, as the turbulence generated through agitation aids
particle suspension, air dispersion and particle–bubble collision. Therefore, it is important to …

It is challenging to measure the hydrodynamics of stirred tank reactors when they contain
multiphase flows comprising liquid, gas bubbles and particles. Radioactive particle tracking …

The analysis of particle–bubble collisions in turbulent flow is a fundamental problem of high
technological relevance, eg, for the separation of valuable mineral particles by froth flotation …

Gas–solid cyclones are broadly employed in the industrial sector. Even though numerical
methods are currently a strong tool for predicting the characteristics of flow patterns inside …

Abstract Computational Fluid Dynamics (CFD) simulations of solid–liquid flows in stirred
tanks are feasible with appropriate closure models. However, no systematic assessment of …
