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

Positron emission particle tracking (PEPT) is a noninvasive technique capable of imaging
the three-dimensional dynamics of a wide variety of powders, particles, grains, and/or fluids …

Multiphase chemical reactors with characteristic multiscale structures are intrinsically
discrete at the elemental scale. However, due to the lack of multiscale models and the …

Positron emission particle tracking (PEPT) is a technique for tracking a single radioactively
labelled particle. Accurate 3D tracking is possible even when the particle is moving at high …

In this work we assess whether particle shape can induce radial segregation in a rotating
cylinder. To this end, mixtures of spheres and non-spherical particles of equal-volume were …

Physicochemical transformation of coffee during roasting depends on the applied time–
temperature profile (ie, rate of heat transfer), with heat transfer phenomena governed by …

The axial segregation of granular and particulate media is a well-known but little-understood
phenomenon with direct relevance to various natural and industrial processes. Over the past …

In this paper, we study the effects of the presence and shape of side walls and of the overall
length of rotating cylindrical drums on the mixing of particles with differing sizes by …

Considering a 3D sheared granular layer through a discrete element modeling, it is well
known the rolling resistance influences the macro friction coefficient. Even if the rolling …

The dynamic behaviour of granular flows is important in geo-mechanics and industrial
applications, yet poorly understood. We studied the effects of liquid viscosity and particle …
