A new approach for estimating the system properties of polydispersed liquid‐solid fluidized bed systems, based on the concept of departure from monodispersed systems, is discussed. The proposed generalized correlation based on experimental data on particulate fluidization can predict minimum fluidization velocity, minimum elutriation velocity, onset of semifluidization velocity, and free‐settling velocity with an accuracy of ±25.7%. The correlation is valid for heterogeneous systems comprising solids of various sizes and/or densities.
