Gas-solid fluidization technology has been commercialized in many industrial applications
since its implementation in the fluid catalytic cracking process in the early 1940s, however …

▪ Abstract This paper reviews recent advances in our understanding of the origin and
hierarchy of organized flow structures in fluidized beds, distinction between bubbling and …

Crossing single-walled carbon nanotubes can be joined by electron beam welding to form
molecular junctions. Stable junctions of various geometries are created in situ in a …

The Discrete Element Model (DEM) is a very promising modelling strategy for two-phase
granular systems. However, owing to a lack of experimental measurements, validation of …

Granular flow in a rotating tumbler is of theoretical and industrial significance. However, in
spite of its relative simplicity, little is known about the dynamics of the top flowing layer. Here …

This paper reports on a numerical study of fluidization behavior of Geldart A particles by use
of a 2D soft-sphere discrete particle model (DPM). Some typical features, including the …

Gas fluidised beds are widely employed in the chemical, petrochemical, metallurgical, and
pharmaceutical industries. Solids mixing in such devices plays a central role in controlling …

The Geldart classification reported in 1973 is widely acknowledged as one of the seminal
papers on fluidization. Today, it remains the most used classification for particle fluidization …

We report on 3D computer simulations based on the soft-sphere discrete particle model
(DPM) of Geldart A particles in a 3D gas-fluidized bed. The effects of particle and gas …
