Longitudinal particle mixing in a screen-packed, gas-solid fluidized bed, 5 cm. I.D. × 100 cm. bed height, has been studied by employing a colorimetric concentration impulse technique. The packings were 1/2-in. × 1/2-in. open-end screen cylinders.
For the screen-packed bed the results were in good agreement with a diffusion model, while the results for the unpacked fluidized bed showed that the simple diffusion model could not be readily applied. A cell model was also developed and compared with the diffusion model. The experimental data were analysed in terms of these models.
