Abstract

Experiments performed on pairs of dynamically similar gas-fluidised beds confirm the validity of scaling relationships, based on purely fluid-dynamic interactions, to bubbling regime behaviour over a wider range of conditions than hitherto reported: ranging from fine powder (Geldart group A), to large particle (Geldart group D) systems. The scaling relationships, however, fail to explain observed slugging regime characteristics, thereby supporting the view that slugging involves a degree of defluidisation, and hence direct frictional interaction between particles.
