Abstract

A hydrodynamic mathematical model is developed for particulate batch fluidization. Longitudinal dispersion in such systems is predicted analytically. It is governed by the particle wake: its size and shedding rate. The wake size is evaluated from photographs and the shedding rate is calculated from boundary layer flow. The predicted Peclet numbers compare very well with experimental data in the flow range of 40 < Re < 2300.
