A condensed review of recent advances accomplished in the development and the
applications of noninvasive tomographic and velocimetric measurement techniques to …

Quantities that need to be measured in gas fluidized-bed systems include solids volume
concentrations, solids velocities and solids mass flows, the vertical and horizontal …

Bubble columns are cylindrical vessels wherein gas is sparged, via a distributor, in the form
of bubbles, into liquid or liquidsolid suspension. Bubble columns serve as multiphase …

This brief review deals with the characterization of multiphase flows needed in reaction
engineering and describes the techniques and methods available to accomplish it. It …

Horizontal drum reactors are widely used in industry for the processing of granular material.
They are ideally suited for chemical processes that require high temperatures at near …

Diffusivity of the solid particles in a 152-mm ID gas–solid fluidized bed was determined at
different regimes of fluidization. The gas was air at room temperature and atmospheric …

Considerable amount of experimental work has been performed to elucidate the behavior of
granular flow inside a rotating drum and it has yet to be clearly understood. However, a …

This work assesses the accuracy of the discrete element method (DEM) for the simulation of
solids mixing using non‐intrusive Lagrangian radioactive particle tracking data, and …

In this study, bubbling fluidization of a sand fluidized bed with different biomass loadings are
investigated by means of the experiments and numerical simulation. The radioactive particle …

The mechanisms of segregation in solids mixing, even in simple rotating drums, are not
clearly understood. Although most past studies have focused on binary mixtures, this work …
