✦ Synopsis

A model for some liquid fluidized beds is examined. This model, suggested by experimental evidence, considers that clusters of solid particles have small oscillatory motions around some fixed points and that density perturbations (pockets) are propagating through the bed. In order to obtain information concerning the properties of these waves one uses Eulerian descriptions for the motions of the particles and of the fluid and looks for periodical solutions for the void fraction and the velocities. The wave velocity with which the density perturbation waves are propagating, represents the velocity of the pockets. Agreement between theory and experiment is obtained.

This paper focuses on scale-up of the dynamic behavior of gas-solids fluidized bubbling reactors. An empirical approach is followed that is based on the observation that the non-linear, hydrodynamic behavior of bubbling fluidized beds is of a chaotic nature. The degree of chaos is quantified by the
