The coexistence of large particles (such as biomass or coal particles) and fine particles in
gas-solid flow is common. In this study, an Eulerian-Lagrangian-Lagrangian method (EMMS …

Coal beneficiation technology using gas-solid fluidized bed is a hot topic in recent decade,
however its proper design and scale-up remain a great challenge due to the very complex …

Heat transfer is a key aspect in the performance of fluidized bed reactors. In particular, the
dense phase heat transfer coefficient, which determines the heat exchanged between the …

A semiempirical model for the mixing of fuel particles in a fluidized bed is presented and
validated against experimental data from the literature regarding lateral fuel mixing. The …

The motion and dynamics of large objects in bubbling gas–solid fluidized beds are complex,
especially for objects with densities similar to those of the bed. In this study, a method …

In the present work, novel numerical simulations using a hybrid model are carried out to
study the motion of objects, representing fuel particles, in a pseudo-2D fluidized bed. The …

Bubbling fluidization has been widely applied in process industries, such as power
generation from coal, renewable energy production, gasification and pyrolysis. In this study …

The effects of internals and gas distributors on the local dynamics of the bubbles in the
conventional gas–solid fluidized bed were studied. Mesh-type internals with different …

Solids mixing affects thermal and concentration gradients in fluidized bed reactors and is,
therefore, critical to their performance. Despite substantial effort over the past decades …

Bubbling fluidization has been widely applied in industrial processes as an effective means
for providing excellent mixing, good heat and mass transfer. Examples include granulation …
