The distribution of gas flow between bubbles and the dense phase in a fluidized bed is considered. By deriving general equations for gas and solids continuity in a freely-bubbling fluidized bed, the possible contributions to the invisible gas flow are formulated. It is shown that the gross assumptio

Experimental evidence for the two-phase theory of fluidization-that all the gas in excess of that required for incipient fluidization rises in the bubble phase-is discussed from two viewpoints. Fist, measurements of the volume flow-rate of bubbles in a two-dimensional fluidized bed are compared with
Hydrodynamic characteristics of a new mode of liquid-solid fluidization, termed as "inverse fluidization" in which low density floating particles are fluidized with downward flow of liquid, are experimentally investigated. The experiments are carried out with low density particles ( < 534 kg/m 3) wh
