Experimental data are presented for two different methods of operating vertical moving fluidized systems of glass spheres and water: free countercurrent fluidization and bottom‐restrained nonfed, or batch, fluidization. Data for a lead‐shot‐and‐water system are also reported. A comparison is made of these data with a generalized theoretical analysis of ideal fluidized systems. The validity of a single characteristic holdup vs. slip‐velocity relationship is illustrated, and consideration is also given to the prediction of flooding in the free countercurrent systems.
