In recent years the use of Computational Fluid Dynamics (CFD) is significantlyincreasing to simulate multi-phase flows. It is invariably emphasized that a necessary steptowards the development of reliable fully predictive CFD models is an extensiveexperimental validation of the simulation results.This work in particular focuses on the CFD simulation of a lab-scale 2D fluidized bed andthe relevant experiments, in order to validate the prediction capability of the used codesand models. It must be emphasized that both experimental and computational quantitativedata have been obtained by means of an original Digital Image Analysis Technique, thatallows coherent comparison of computational and experimental data.Due to the great importance of bubbles dynamic in affecting the fluidization quality, thiswork analyzes the capability of the CFD simulations in predicting the fluctuatingbehaviour of fluidized beds, by means of frequency analysis of bubbles relatedphenomena.
