Digital Image Analysis Technique for Mixing Pattern Measurements in Bi-dispersed 2D Gas Fluidized Beds

none5This work concerns a new experimental technique based on Digital Image Analysis for the measurement of the mixing behaviour in a bi-dispersed 2D fluidized bed. Two different sets of particles are fluidized with the same density and different size. The technique is based on suitable color-field decomposition of the fluidized bed snapshots, where particles of different colors are employed. The technique here proposed can effectively measure the concentration field in the whole bed during operation and capture the mixing and segregation dynamics of powders. Notably, the technique here developed can be used for both gas- or liquid- fluidized beds.noneBusciglio A.; Vella G.; Mangano E.; Micale G.; Rizzuti L.;Busciglio A.; Vella G.; Mangano E.; Micale G.; Rizzuti L.
