CFD-DEM is used to simulate solid–fluid systems. DEM models the motion of discrete
particles while CFD models the dynamics of the fluid phase. Coupling both necessitates the …

In this work, we assess the accuracy of the unresolved CFD-DEM method by confronting
simulated and experimental results of a pilot-scale cylindrical liquid–solid fluidized bed. We …

Experiments for the validation of unresolved CFD-DEM software for solid–liquid flows are
often expensive, time consuming and generally provide little insight into the local particles …

Immiscible two-phase flow in porous media is crucial in various industrial processes,
necessitating a robust numerical tool to capture this complex multiscale behavior. This paper …

Abstract The volume-averaged Navier-Stokes equations (VANSE) play a key role in
simulating multiphase flow and fluidization. However, the lack of effective models for VANSE …

We propose a novel method to calculate the local void fraction in solid–fluid Euler–Lagrange
models in an attempt to better predict the behavior of multiphase flows in complex …

Fluidised granular beds are used in a variety of industrial applications, such as heat
exchangers, chemical reactors and energy storage systems. Fluidisation increases the …

In this work, we assess the internal dynamics of particles in liquid-solid fluidized beds using
an unresolved CFD-DEM model. We use the Nearest Neighbors Method (NNM) and the …

This work is dedicated to the pressure-correction projection method for the volume-averaged
Navier–Stokes system for porous media. A set of parameters controlling the presence of …

Recently, we notice that a pressure-based lattice Boltzmann (LB) method was established to
recover the volume-averaged Navier-Stokes equations (VANSE), which serve as the …
