Abstract
The analogy between the states of a particle falling at its terminal velocity in a fluid and that of a particle in a bed, at incipient fluidization by the same fluid, suggests the possibility of a correlating minimum fluidizing and terminal velocities and of predicting the minimum fluidizing velocity. A semi‐theoretical curve has been obtained, relating (Ret/Remf) to Fn = gpF (rHS – rHF) d3/μ2 and it has been compared with new experimental data collected for this purpose in the range 103<Fn8. Analytical expressions for (Ret/Remf) are proposed.Keywords
