摘要：The gas velocity interval for initiating gas fluidization of binary mixtures of Geldart type B particles has been thoroughly investigated experimentally and theoretically by Formisani et al.[2–6] The same approach has now been applied in our laboratory to liquid fluidization of binary macro‐solids. Experimental results for water fluidization in a 190.5 mm diameter column of initially well mixed packed beds, consisting of different volumetric fractions of 1.91 mm and 4.54 mm glass spheres of density 2510 kg/m3, are well predicted by the methods of Formisani et al., whether the equations are based on random‐dense voidages as practiced by that group, or based on random‐loose voidages as commonly used for monocomponent solids.
