Abstract

Experiments were performed on a gas-solid fluidized system investigating the response of the bed to harmonic oscillations. An alumina oxide/air fluidized bed was harmonically excited by externally shaking the bed. Resonances close to those for incompressible fluids were found, although the system was greatly overdamped. It was also found that for a weakly homogeneous system, forced excitations caused the mean surface level of the bed to drop in height. If sufficient amplitude of external forcing was present, the height of the bed was seen to rise prior to the onset of the most unstable sloshing mode. Conversely, if amplitudes were sufficiently small, no resonance was seen and bed height was observed to drop continuously.
