Modeling of heterogeneous materials and media is a problem of fundamental importance to
a wide class of phenomena and systems, ranging from condensed matter physics, soft …

In this paper we study the effect of rolling friction on the dynamics in a single spout fluidized
bed using Discrete Element Method (DEM) coupled to Computational Fluid Dynamics …

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 …

The combination of Computational Fluid Dynamics (CFD) and Discrete Element Model
(DEM) is a powerful tool for studying fluidized particulate systems and granular flows. In …

In the past few decades, multi-scale numerical methods have been developed to model
dense gas-solid flow in fluidized beds with different resolutions, accuracies, and efficiencies …

Piping, as one of the critical patterns of internal erosion, has been reported as a major cause
for failures of embankment dams and levees. The fundamental mechanism of piping was …

A comprehensive frictional-kinetic model for collisional and frictional gas–particle flows is
presented. The model treats gas and particles as a continuum. The kinetic-collisional …

This study develops filtered two-fluid model (fTFM) closures by coupling computational fluid
dynamics (CFD) and deep learning algorithm (DL) for enabling coarse-grid simulations at …

Multiphase flows in porous and granular media are widely encountered in many research
and engineering fields. Due to the complexity and limited accessibility of real facilities, it can …
