Spouting behaviour of binary mixtures in square-based spouted beds
Particuology, 2019Abstract From experiments, the influence of the physical characteristics of different binary mixtures of solids on the spouting regime of a pyramidal square-based spouted bed reactor is assessed. The applied methodology permits a more precise evaluation of the effects of the tested variables (diameter, density, sphericity) on the response variables ...

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 ...

AbstractThe first commercial spouted bed driers have been installed in Canada and one has been used to dry three types of peas, lentils and flax. The data obtained from this drier have been compared and correlated with previous drying studies in various laboratory spouted bed driers.

Determination of Minimum Spouting Velocities in Conical Spouted Beds
The Canadian Journal of Chemical Engineering, 2004AbstractMinimum spouting velocities in conical spouted beds have been obtained from pressure drops versus the superficial gas velocity curves, based on both increasing and decreasing the superficial gas velocity. It has been shown that the minimum spouting velocity from decreasing the superficial gas velocity is lower than from increasing the ...

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 ...

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

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.

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.
