Positron emission particle tracking (PEPT) is a technique which allows the high-resolution,
three-dimensional imaging of particulate and multiphase systems, including systems which …

Gas-solid fluidized-bed systems offer great advantages in terms of chemical reaction
efficiency and temperature control where other chemical reactor designs fall short. For this …

The influence of bed composition–that is, the relative proportions of different components–
on the mixing of fluidised beds containing mixtures of Geldart group B and D particles is of …

We computationally study the micromechanics of shear-induced size segregation and
propose distinct migration mechanisms for individual large and small particles. While small …

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 …

The paper investigates the effects of changing the particle–particle restitution and sliding
friction coefficients of grinding media within a vertical stirred mill using the discrete element …

Rock‐ice avalanches occurring in cold high‐mountain regions often cause catastrophic
damages due to their extremely high mobility. Rock and ice have different physical …

Abstract Positron Emission Particle Tracking (PEPT) is a Lagrangian particle tracking
technique useful for imaging flow in opaque granular media. The scientific and industrial …

Extremely useful techniques exist to observe the interior of deforming opaque materials, but
these methods either require that the sample is replaced with a model material or that the …

Discrete particle simulations provide a powerful tool for the advancement of our
understanding of granular media, and the development and refinement of the multitudinous …
