Mineral grains serve as the basic units of rocks. Understanding rock materials at the grain-
scale level allows us to unveil the underlying fundamental mechanisms, thereby facilitating …

It is challenging to model granular particles with arbitrary shapes and related complications
to fluid–particle interactions for granular flows which are widely encountered in nature and …

Suffusion involves fine particles migration within the matrix of coarse fraction under seepage
flow, which usually occurs in the gap‐graded material of dams and levees. Key factors …

In this paper, we develop a numerical model for simulating the solid-liquid-gas three-phase
flow in unconsolidated particle layers. Based on the discrete element method (DEM) and the …

The goal of seeking advanced solutions to the descriptions of particle shape, packing and
tomographic measurement were key areas promoted by Professor Reg Davies. In this paper …

It remains a challenge for discrete element method to simulate large-scale systems with
arbitrarily shaped particles. This paper presents a novel approach called Ray Tracing …

The stability and mobility of proppant packs in hydraulic fractures during hydrocarbon
production are numerically investigated by the lattice Boltzmann-discrete element coupling …

The investigation of fish swimming is prevalent in the fields of biomimetic hydrodynamics
and is important for research on the temporal–spatial evolvement of vortex structures around …

Transient dynamics of fracturing media has received significant attention in recent years,
and a number of simulation approaches have been developed. One of these is the …

Suffusion refers to a special form of internal erosion characterized by the selective erosion of
the finest particles of a soil under the action of an internal fluid flow. In this work, the …
