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
transfer from bubbles to the dense phase in a fluidized bed is described as a combination of diffusional and convective processes. In the convective process the cloud formation is important as is the adsorption of the gas at the solid interface. The resulting differential equations are worked out nu
