Experimental analysis of heat transfer in packed beds with air flow
(2004-07-21)
Heat-transfer studies were carried out in a packed bed of glass beads, cooled by the wall, through which air percolated. Tube-to-particle diameter ratios (D/dp) ranged from 1.8 to 55, while the air mass flux ranged from ...

Packed-Bed Photocatalytic Reactors. A Packing Structure Model and Its Experimental Validation with Computerized Tomography
(American Chemical Society, 2004-12)
A statistical model is proposed for the description of the spatial structure of a packed bed of spherical-like particles in terms of one- and two-bead distribution functions. This is the first step toward the full modeling ...
Evaluation of structural properties of cylindrical packed beds using numerical simulations and tomographic experiments
(De Gruyter, 2009-12-01)
This contribution is focused on the analysis of the structure of packed beds of spherical particles at relatively low aspect ratios (i.e., particle to tube diameter ratio) as those arising in multitubular fixed bed reactors. ...
Effect of biocatalyst swelling on the operation of packed-bed immobilized enzyme bioreactor
(Elsevier, 2008-10)
A general mathematical model was developed for predicting the performance and simulation of a packed-bed immobilized enzyme reactor performing a reaction that follows Michaelis–Menten kinetics with competitive product ...
An algorithm to simulate packing structure in cylindrical containers
(Elsevier Science, 2005-10)
The aim of this work is to propose an algorithm to simulate the packed bed structure of mono-sized spheres in cylindrical containers. The approach employed is called soft spheres algorithm, because it allows some degree ...
EXPERIMENTAL STUDY OF A ROTATING PACKED BED DISTILLATION COLUMN
(Brazilian Soc Chemical EngSao PauloBrasil, 2009)
Predicting the packed-bed reactor performance with immobilized microbial lactase
(Elsevier, 2006-12)
A mathematical model for several working conditions was numerically solved to study a fixed bed reactor with a biocatalyst. The effect of bed swelling, mass transfer limitations, axial dispersion, residence times and inlet ...
Structural properties of beds packed with agro-industrial solid by-products applicable for solid-state fermentation: Experimental data and effects on process performance
(Elsevier B.V., 2014-11-01)
The knowledge of structural properties of beds packed with particles from agro-industrial solid wastes is important for modeling and simulation of heat and mass transfer in solid-state fermentation (SSF) in packed-bed ...
