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.
