Prediction of spout diameter in a spouted bed—A theoretical model
Powder Technology, 1972Abstract A theoretical equation for spout diameter has been derived from a force balance analysis which, in addition to the hydrodynamic forces, also takes into account solid stresses based on hopper flow of solids. The functional form of the equation is supported by a wide range of experimental data, the value of the multiplying coefficient showing ...

Hydrodynamics of spouted and spout‐fluidized beds at high temperature
The Canadian Journal of Chemical Engineering, 1992AbstractHydrodynamic parameters were investigated in a 0.15 m diameter half‐column spout‐fluidized bed at temperatures up to 880°C for ratios of auxiliary air flow to total air flow from 0 to 0.62 and four narrow size ranges of silica sand. Equations in the literature gave poor agreement with the minimum spouting velocity over the entire temperature ...

Low temperature drying of pomace in spout and spout-fluid beds
Journal of Food Engineering, 2007The solid residue that originates from virgin olive oil production has a consistency that falls between a paste and a particulate solid, consists of two phases: the crushed olive kernel and the fruit pulp. The kernel particles can be used as high quality solid fuel, while oil can be extracted from the pulp residue.

Numerical simulation of spouting of cylindroid particles in a spouted bed
The Canadian Journal of Chemical Engineering, 2013AbstractThe hydrodynamic behaviours of cylindroid particles in a spouted bed are studied by three‐dimensionally coupled computational fluid dynamic (CFD) and discrete element method (DEM) model. The cylindroid particles are constructed by multi‐sphere method. The drag coefficient model for non‐spherical particles is employed which shows higher accuracy

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.

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.
