PEPT and discrete particle simulation study of spout‐fluid bed regimes
AIChE Journal, 2008AbstractThe results of a combined experimental and simulation study on the flow regimes that can be encountered during spout‐fluid bed operation are reported. A regime map for a three‐dimensional (3D) spout‐fluid bed was composed, employing spectral analysis of pressure drop fluctuations and fast video recordings.

Solid circulation in a liquid spout-fluid bed with multi draft tubes
Journal of Chemical Technology & Biotechnology, 1998Considering the application of the technique of liquid spouting with multi draft tubes to heat exchangers, the solids circulation rate was studied both experimentally and theoretically. It was found that the solids circulation rate increased with the liquid velocity and with the amount of solids used.

Spouted bed and spout‐fluid bed behaviour in a column of diameter 0.91 m
The Canadian Journal of Chemical Engineering, 1992AbstractHydrodynamic measurements were obtained in a half‐column of diameter 0.91 m equipped with a conical base using particles of diameter 3.3 to 6.7mm with operation both as pure spouted beds and in the spout‐fluid bed mode. Comparison of the experimental results for minimum spouting velocity with equations in the literature generally gave ...

Hydrodynamic studies of spouted and spout-fluid beds
2009Hydrodynamic experiments were conducted in a three-dimensional spout-fluid bed with a specially designed conical distributor to supply the auxiliary air. The vessel used was a cylindrical column, 0.15 m in diameter and 1.05 m high fitted with an inlet orifice plate with a diameter of 19.1 mm.

A Comparative Study of Spouted and Spout-Fluid Beds for Tablet Coating
Drying Technology, 2005Abstract The performance of spouted, spouted with auxiliary air supply, and spout-fluid beds for the coating of tablets was investigated. The gas–solid regimes of the three systems were confirmed by their hydrodynamic characteristic curves, e.g., pressure drop versus air flow rate.

Separation and residence times of larger particles in a spout‐fluid bed
The Canadian Journal of Chemical Engineering, 1992AbstractOptimum conditions for the separation of added large particles from a spout‐fluid bed of Geldart Type B powder have been determined. A shallow bed, 100 mm in diameter, with porous conical distributor was used. Mean and distributions of residence time of the large particles depend on the two gas flow rates, especially that to the distributor ...

Spouted bed and spout-fluid bed hydrodynamics in a 0.91 m diameter vessel
2010Experiments were conducted in a 0.91 m diameter half-cylindrical spouted bed/spout-fiuid bed column equipped with a 60° conical base and semi-circular inlet orifice diameters of 76 to 140 mm. Three particulate solid materials were studied: 3.25 mm polystyrene, 4.72 mm brown beans and 6.71 mm green peas.
