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

Landslide-generated waves (LGWs) are among natural hazards that have stimulated
attentions and concerns of engineers and researchers during the past decades. At the same …

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 …

Numerical simulations of viscoplastic fluid flows have provided a better understanding of
fundamental properties of yield stress fluids in many applications relevant to natural and …

In light of the successes of the Navier–Stokes equations in the study of fluid flows, similar
continuum treatment of granular materials is a long-standing ambition. This is due to their …

The so-called coarse-grained discrete element method (DEM) is used here for efficient
simulations of large-scale particle systems as its effectiveness has been successfully verified …

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 …

Environmental fluid mechanics underlies a wealth of natural, industrial, and, by extension,
societal challenges. In the coming decades, as we strive towards a more sustainable planet …

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 …

Continuum modelling of granular flow has been plagued with the issue of ill-posed dynamic
equations for a long time. Equations for incompressible, two-dimensional flow based on the …
