Modeling of particle size segregation: calibration using the discrete particle method
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 …

Underlying asymmetry within particle size segregation
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 armouring as a granular segregation phenomenon
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 …

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

Theory for shear-induced segregation of dense granular mixtures
It is well known that a mixture of different sized particles will segregate in a gravitational field.
However, it has only recently been shown that a gradient of shear rate alone can drive …
