Propagation of voidage waves in a two-dimensional liquid-fluidized bed. (English) Zbl 1134.76642

Summary: Digital video recordings were used to obtain voidage distribution in a narrow fluidized bed with a small gap slightly larger than three particle diameters. From these recordings we determined auto-correlations and power spectra in spatial and temporal and joint spatial-temporal power spectra. Increases in the fluidization velocity lead to increasing disorganized non-periodic flows. Our experimental results are discussed in the light of experimental results and theories found in literature.
