As a step toward a unified treatment of particulately fluidized beds, a statistical‐thermodynamic approach has been investigated, with the smoothed potential cell theory of pure liquids used to establish an equation of state and a collisional‐viscosity relation. This treatment has correlated well with experimental data on liquid‐fluidized beds, and the same method gives reasonable predictions for gas‐fluidized beds. A parameter equivalent to thermodynamic temperature has been identified for fluidized beds, which depends solely upon fluid properties and includes the three‐halves power of superficial velocity. This approach should be of value for interpreting other liquidlike properties of fluidized systems.
