A simple predictive model is presented here to describe the layer inversion behaviour of binary solidÈliquid Ñuidized beds. The model is based on the assumption that the concentrations of the two particle species in the binary bed when normalized with respect to their mono-component counterparts are

✦ Synopsis
The concept of complete segregation of a binary-solid particulate fluid&d bed is generalized to accommodate cases where the bottom zone contains an equilibrium mixture of the two solid components. The model is fully predictive and provides a complete explanation of the "inversion phenomenon" in close agreement with recently published experimental studies.

Predicting the stratification pattern of a binary or ternary solid-liquid fluidized bed requires not only the calculation of the volume fractions of particles in mixed and mono-component layers but also the specification of the order and the thickness of the layers in the bed. A model was developed
