Multiphase chemical reactors with characteristic multiscale structures are intrinsically
discrete at the elemental scale. However, due to the lack of multiscale models and the …

Computational modeling has played a key role in advancing the performance and durability
of polymer electrolyte membrane fuel cells (PEMFCs). In recent years there has been a …

Lattice Boltzmann method (LBM) is a relatively new simulation technique for the modeling of
complex fluid systems and has attracted interest from researchers in computational physics …

The flow direction is generally different from the gravity direction in geotechnical structures
or slopes, the effect of which during suffusion remains unclear. This paper presents a …

Abstract A semi-resolved CFD-DEM model is proposed to model the seepage-induced fine
particle migration within the gap-graded soils consisting of fine and coarse particles. In this …

The discrete element modelling of triaxial tests plays a critical role in unveiling fundamental
properties of particulate materials, but the numerical implementation of a flexible membrane …

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 …

This paper presents a serial computational framework that hydrodynamically couples the
lattice Boltzmann method (LBM) and the discrete element method (DEM) for the solution of …

In the present paper a coupling law between the Lattice Boltzmann Method (LBM) for fluids
and the Discrete Element Method (DEM) is introduced to study problems involving the …

The clogging of a stream bed has a significant impact on the exchange of water between a
river and groundwater, known as hyporheic exchange. Clogging issues in orifices …
