Abstract Fine-grid Euler–Lagrange simulations of gas-fluidization of uniformly sized particles
have been performed in three-dimensional periodic domains. Snapshots obtained from …

Euler-Lagrange simulations of gas-solid flows in unbounded domains have been performed
to study sub-grid modeling of the filtered drag force for non-cohesive and cohesive particles …

Abstract Although Euler-Lagrange simulations can be performed with millions of particles,
particle coarsening where particles are replaced by parcels is necessary for simulation of …

The ability to model granular systems at the level of individual particles has largely
conduced to the success of the discrete element method (DEM). At the same time, this …

Studies on powder mixing in industrial mixers are crucial for the improved criteria of mixing
equipment design and optimization within various mixing unit operations. In the present …

Wet fluidization occurs when small amounts of liquid are injected into a fluidized bed,
causing liquid bridges to form between particles. These liquid bridges create complex …
