Packed bed structure: Evaluation of radial particle distribution
(John Wiley & Sons Inc, 2002-04)
A model describing the radial distribution of monosized spheres in randomly packed beds up to distances of about two particle diameters from the vessel wall is presented here. The model is based on the existence of a highly ...
Computing radial packing properties from the distribution of particle centers
(Pergamon-Elsevier Science Ltd, 2001-10)
The relationship between the distribution of particle centers in random beds of uniformly sized spheres and radial properties, in particular radial voidage profiles, is undertaken in this work. To this end, closed expressions ...
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 ...
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 ...

Estudo fluidodinâmico e térmico no transportador pneumático com alimentador tipo jorro
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2009-08-05)
The pneumatic conveyor using a spouted bed as a particle feeding method has been studied in the past years in the Centro de Secagem/DEQ/UFSCar. In the literature there are some studies related to the fluid dynamics behavior ...
