Particle Mixing and Segregation in Gas-Solid Fluidized Beds Containing Binary Mixtures

A newly developed Digital Image Analysis (DIA) technique has been used to study the dynamics of axial segregation of binary mixtures in gas-solid fluidized beds. Experimental results have been compared with a soft-sphere Discrete Element Model (DEM) in which bed conditions were formulated to be in conformity with laboratory experiments.
