N2 - Voidage inhomogeneities in fluidized beds may rapidly decay or grow to result respectively in unambiguously stable (particulate) or unstable (aggregate) behaviour. Where growth or decay rates are small, disturbances may propagate through the bed at effectively constant amplitude. This phenomenon is examined in the light of a predictive model of the fluidized state; this provides a general criterion for indeterminate stability, in good agreement with both new and previously published observations, that leads to a global map for the quality of fluidization by ambient water.
