Correct prediction of spontaneous bubble formation in freely bubbling gas–solid fluidized beds using Eulerian models, strongly depends on the description of the internal momentum transfer in the particulate phase. In this part, the comparison of the simple classical model, describing the solid phase pressure only as a function of a solid porosity by an

Local solid mixing in gas–solid fluidized beds
Powder Technology, 2001Abstract 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 pressure and the solids were 385 μm sand or 70 μm FCC particles.

Gas‐solid contact in fluidized beds
AIChE Journal, 1955AbstractAccording to the concept of two‐phase fluidization, a part of the gas in a fluidized reactor passes through the uniform dispersed solid‐gas phase in the form of bubbles, channels, and slugs. Material transport by mixing or diffusion takes place at the phase boundaries.

Fluidization of Biomass Particles in a Gas−Solid Fluidized Bed
Energy & Fuels, 2008Studies on the fluidization of biomass particles and binary mixtures of biomass particles with fluidization mediums were carried out. The biomass particles used were wood chip, mung beans, millet, corn stalk, and cotton stalk, and the fluidization mediums employed were silica sand, continental flood basalt (CFB) cinder, and aluminum oxide.

Filtration of nano-particles by a gas–solid fluidized bed
Journal of Hazardous Materials, 2007The filtration of 80 nm SiO2 and Al(2)O(3) particles in a gas stream using fluidized beds was studied. Silica sand and activated carbon (A.C.) were adopted as bed materials to filtrate 80 nm SiO2 and Al(2)O(3) particles. The collected particles were elutriated from the fluidized bed, so the filtration was a dynamic process and the variations of the ...

Characterization of dynamic gas–solid distribution in fluidized beds
Chemical Engineering Journal, 2000Abstract A probability distribution model of the local voidage was proposed to describe and simulate dynamic gas–solid distribution in the bubbling and turbulent fluidized bed reactors. Experiments were carried out in an air-fluidized bed. The bed materials were FCC particles (Geldart A) and irregular sand particles (Geldart B). A cross-optical fiber
