The coupling between fluid and granular materials is commonly encountered in nature and
engineering practice. Moreover, the shape of granular materials in practical applications is …

Sediment transport simulations face the challenge of accounting for vastly different scales in
space and time that cannot be tackled by a unifying approach. Instead, processes are …

When the unresolved CFD-DEM (Computational Fluid Dynamics and Discrete Element
Method) method is used to solve two-phase flow (composed of fracturing fluid and quartz …

The article proposes an algorithm to model the collision between arbitrary ellipsoids in
viscous fluid. It is composed of several steps, each improving upon the standard procedure …

Rock block removal is the prevalent physical mechanism for rock erosion and could affect
the stability of dam foundations and spillways. Despite this, understanding of block removal …

A three-dimensional Eulerian two-phase flow model for sediment transport in sheet flow
conditions is presented. To resolve turbulence and turbulence-sediment interactions, the …

Theoretical analysis and nowadays advanced numerical simulations for bedload particle
transport widely share a popular assumption: All sediments are spherical and can be …

Coastal sediment transport of graded spherical particles with the material properties of sand
was simulated and compared to transport of the uniform-sized spherical particles using a …

A clogging layer would be formed on surface of the prefabricated vertical drain (PVD) when
the dredged slurry is treated using the vacuum preloading method. The clogging layer …

Low effective stress in the fine fraction of internally unstable materials is the key mechanism
leading to the internal instability. In the present study, the effects of stress state and fine …
