TL;DR: The behavior of solids fluidized by gases falls into four clearly recognizable groups, characterized by density difference (ϱs −ϱf) and mean particle size as discussed by the authors, and a numerical criterion which distinguishes between groups A and B has been devised and agrees well with published data.
TL;DR: In this article, the origin of Bubbles is discussed, and the theory of Granular Mixtures is presented, along with the application of Kinetic Theory in the field of Continuum Problems.

TL;DR: In this paper, a predictive two-phase flow model was derived starting with the Boltzman equation for velocity distribution of particles, which is a generalization of the Navier-Stokes equations of the type proposed by R. Jackson, except that the solids viscosities and stresses are computed by simultaneously solving a fluctuating energy equation for the particulate phase.
Abstract: Detailed knowledge of solids circulation, bubble motion, and frequencies of porosity oscillations is needed for a better understanding of tube erosion in fluidized bed combustors. A predictive two-phase flow model was derived starting with the Boltzman equation for velocity distribution of particles. The model is a generalization of the Navier-Stokes equations of the type proposed by R. Jackson, except that the solids viscosities and stresses are computed by simultaneously solving a fluctuating energy equation for the particulate phase. The model predictions agree with time-averaged and instantaneous porosities measured in two-dimensional fluidized beds. Observed flow patterns and bubbles were also predicted.
