Evaluation of radial voidage profiles in packed beds of low-aspect ratios
(John Wiley & Sons Inc, 2000-12)
The relationship between the radial voidage profile, ϵ(r), and the radial distribution of centres of mono‐sized spherical particles, f(r), is revised. A close expression is given for the section S(r1, rc), the area of the ...
Biosorption of chromium(VI) using a Sargassum sp packed-bed column

Heat transfer in packed-beds of agricultural waste with low rates of air flow applicable to solid-state fermentation
(2018-10-12)
Heat transfer studies were carried out in packed-beds (PBs) heated by the wall and percolated by low air flow rates. Porous media were composed by particles of sugarcane bagasse (SCB) and by a mixture of particles of SCB, ...

Fluid dynamics of air in a packed bed: velocity profiles and the continuum model assumption
(Brazilian Society of Chemical Engineering, 1999-12-01)
Air flow through packed beds was analyzed experimentally under conditions ranging from those that reinforce the effect of the wall on the void fraction to those that minimize it. The packing was spherical particles, with ...

Effect of radial velocity profiles on axial dispersion in packed beds: asymptotic behaviour
(Brazilian Society of Chemical Engineering, 2021-09)
Axial dispersion of a solute in a flow through packed beds arises from molecular diffusion, velocity variations at the interstitial-pore scale and systematic radial velocity profiles. Currently, there is not a widely ...
Modeling of a TiO2-Coated Quartz Wool-Packed Bed Photocatalytic Reactor
(Elsevier Science, 2010-03)
A fixed-bed, photocatalytic laboratory reactor aimed to degrade pollutants from water streams was designed and built. Quartz wool coated with a thin film of TiO2 was employed as the reactor filling. The photocatalyst was ...
