Abstract

Particulate fluidization and sedimentation data were taken over the Reynolds number range of 0.005 to 1,800 by means of glass spheres in both water and ethylene glycol. Porosities for each series of measurements varied from about 0.50 to 0.91 and larger. The closely sized samples of spheres used were obtained by grinding between glass plates. The data for Reynolds numbers up to about 0.5 are in excellent agreement with the laminar theory of Ruth and the porosity function from Ruth's theory gave a satisfactory correlation of all the data, both laminar and turbulent.

## Abstract Agglomerate particulate fluidization (APF), consisting of uniform bubbleless fluidization of agglomerated fine particles, has been observed in some fluidized beds of fine and ultrafine powders. Experiments performed in centrifugal fluidized beds (CFB) and vibrofluidized beds (VFB) show
