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
Theory is given to predict the value of k in the equation for a bubbling fluidised bed U=kUo+ QB/A; here U is the superficial fluidising velocity, U= U0 at incipient fluidisation, Qn is the observed bubble flow, and A the cross-sectional area of the bed. In the simple two-phase theory, k = 1 ; but t
