Granular materials composed of particles with differing grain sizes, densities, shapes, or
surface properties may experience unexpected segregation during flow. This review focuses …

Content uniformity (CU) of the active pharmaceutical ingredient is a critical quality attribute of
tablets as a dosage form, ensuring reproducible drug potency. Failure to meet the accepted …

We introduce the open-source package MercuryDPM, which we have been developing over
the last few years. MercuryDPM is a code for discrete particle simulations. It simulates the …

During the last fifteen years there has been a paradigm shift in the continuum modelling of
granular materials; most notably with the development of rheological models, such as the …

Understanding the physics of phase separation between solid and fluid phases as a mixture
mass moves down-slope is a long-standing challenge. Here, we propose an extension of a …

Heap formation occurs widely in industry when particulate materials are filled into vessels
such as hoppers, silos, bulk bags and bins. If the bulk materials are composed of particles …

Size segregation, which is a robust feature of sheared granular mixtures and geophysical
mass flow deposits, is found to diminish in the presence of a viscous fluid. We study this …

Modeling segregation of size disperse granular materials during hopper discharge is
important as hoppers are widely used in various industries. However, due to the complexity …

In this work, smoothed particle hydrodynamics (SPH) is employed to investigate the
segregation evolution in granular flows. We first provide the Lagrangian description-based …

Particle segregation is common in natural and industrial processes involving flowing
granular materials. Complex, and seemingly contradictory, segregation phenomena have …
