Propagation of Voidage Waves In A 2-dimensional Liquid-fluidized Bed

Abstract

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 Rows. Our experimental results are discussed in the light of experimental results and theories found in literature.
