In this study a prismatic spouted bed was characterized experimentally and modelled by
means of 3D CFD-DEM simulations. The main focus was on the investigation of the …

Spout deflection is a common instability phenomenon in spout fluidized beds. However,
spout deflection was not well characterized and quantified in the past. In this work, spout …

In this paper, a new flow regime is identified by applying an umbrella-like baffle in a
rectangular spout fluidized bed and studied by Computational Fluid Dynamics-Discrete …

Spouted beds operation quality and stability often suffer from spout deflection, which means
the spout channel shows a lateral movement instead of vertical spouting. A comprehensive …

In this work, a coupled computational fluid dynamics–discrete element method (CFD–DEM)
approach was employed to evaluate the spouting behavior of fine, cohesive powders in a …

Abstract Cycle Time Distribution (CTD) plays a critical role for determining uniformity of
particle coating in spray fluidized beds. However, the CTD is influenced by both geometrical …

The gas–solid contact in spouted beds is characterized by a hydrodynamics leading to high
heat and mass transfer rates. Several correlations have been proposed for estimating the …

In many processes, particles are coated or agglomerated. Thus, it is of considerable interest
how liquid affects the particle dynamics. The production of round, coated pellets is …

A study has been carried out on the hydrodynamic performance of a fountain confinement
device used in conical spouted beds for the treatment of Geldart A and B type particles …

The spout deflection problem limits the operating range and poses a threat to the normal
production of fluidized beds especially when the cohesive particles are practised, yet these …
