This paper reviews the use of discrete particle models (DPMs) for the study of the flow
phenomena prevailing in fluidized beds. DPMs describe the gas-phase as a continuum, whereas …

Gas-solid fluidized beds are widely applied in many chemical processes involving physical
and/or chemical transformations, and for this reason they are the subject of intense research …

This paper reviews the use of direct numerical simulation (DNS) models for the study of mass,
momentum and heat transfer phenomena prevailing in dense gas–solid flows. In particular…

In this paper a three-dimensional (3D) volume of fluid (VOF) method is presented featuring (i)
an interface reconstruction technique based on piecewise linear interface representation, (ii…

In this work the use of large eddy simulations (LES) in numerical simulations of the gas–liquid
flow in bubble columns is studied. The Euler–Euler approach is used to describe the …

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 (CFD). …

Numerical simulations of the bubbly flow in two square cross-sectioned bubble columns
were conducted with the commercial CFD package CFX-4.4. The effect of the model constant …

Spout–fluid beds find a widespread application in the process industry for efficient contacting
of large particles with a gas. However, detailed understanding of the complex behavior of …

The discrete modelling and understanding of the particle dynamics in fluidized bed apparatuses,
mixers, mills and others are based on the knowledge about the physical properties of …

In this paper a novel simulation technique is presented to perform Direct Numerical Simulation
(DNS) of fluid flow and heat transfer in dense fluid–particle systems. The unique feature of …
