Modeling of heterogeneous materials and media is a problem of fundamental importance to
a wide class of phenomena and systems, ranging from condensed matter physics, soft …

Self-assembly of various building blocks has been considered as a powerful approach to
generate novel materials with tailorable structures and optimal properties. Understanding …

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

This review article provides an overview of dry granular flows and particle fluid mixtures,
including experimental and numerical modeling at the laboratory scale, large scale …

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 …

River bed-load transport is a kind of dense granular flow, and such flows are known to
segregate grains. While gravel-river beds typically have an “armoured” layer of coarse …

Accurate continuum models of flow and segregation of dense granular flows are now
possible. This is the result of extensive comparisons, over the last several years, of computer …

When granular materials flow, the constituent particles segregate by size and align by
shape. The impacts of these changes in fabric on the flow itself are not well understood, and …

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

This paper presents image velocimetry measurements on turbulent flows adjacent to a
permeable bed made of randomly packed glass particles. For measuring flow velocities …
