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

Hydrocarbon separations are crucial to the chemical industry for the production of valuable
feedstocks. However, their structural and chemical similarities have proven daunting …

This review focuses on how the modeling of dense granular media has advanced over the
last 15 years. The jumping-off point of our review is the μ (I) rheology for dry granular flow …

Debris flows are typically a saturated mixture of poorly sorted particles and interstitial fluid,
whose density and flow properties depend strongly on the presence of suspended fine …

Carbon capture and storage (CCS) technologies are the “knight in shining armor” that can
save humanity from burnout in the longer term, minimizing damage from CO2 emissions by …

Predicting segregation of granular materials composed of different-sized particles is a
challenging problem. In this paper, we develop and implement a theoretical model that …

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 …

We experimentally study particle scale dynamics during segregation of a bidisperse mixture
under oscillatory shear. Large and small particles show an underlying asymmetry that is …

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 …
