"An analysis method is developed and applied which employs spectra of the Fast Fourier Transform of measured pressure fluctuations within the fluidized bed. The procedure is based upon the spectral analysis of successive time series of pressure fluctuations reflecting the actual hydrodynamic state of the bed. Practical application of the method is illustrated for fluidization at ambient temperature and pressure of spherical particles (glass beads) as well as irregularly shaped particles (limestone, sulfated limestone, and dried sewage sludge), in an 8-cm \u2013 ID fluidized bed. Using air, experiments were conducted with different fractions of the materials spanning a very wide range of 0.28 \u2013 4.5 mm. The evolution was explored of bed behavior from the onset of fluidization to pneumatic transport (elutriation) of solids from the bed. The method recognizes alterations of the hydrodynamic state of the bed caused by minor changes in the bed mass and/or in the granularity of the bed material" . .
