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

Data from large‐scale debris‐flow experiments are combined with modeling of particle‐size
segregation to explain the formation of lateral levees enriched in coarse grains. The …

Over the last 25 years a lot of work has been undertaken on constructing continuum models
for segregation of particles of different sizes. We focus on one model that is designed to …

A general continuum theory for particle-size segregation and diffusive remixing in
polydisperse granular avalanches is formulated using mixture theory. Comparisons are …

We experimentally investigated how a binary granular mixture made up of spherical glass
beads (size ratio of 2) behaved when flowing down a chute. Initially, the mixture was …

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 …

Stratification patterns are formed when a bidisperse mixture of large rough grains and
smaller more mobile particles is poured between parallel plates to form a heap. At low flow …

Particle size segregation can have a significant feedback on the motion of many hazardous
geophysical mass flows such as debris flows, dense pyroclastic flows and snow avalanches …

We model bidisperse size segregation of granular material in quasi-two-dimensional circular
tumbler flow using the advection–diffusion transport equation with an additional term to …

Particle-size segregation can have a significant feedback on the bulk motion of granular
avalanches when the larger grains experience greater resistance to motion than the fine …
