摘要：

Based on the analysis of the processes of full and partial fluidization of a mixture of particles of wide fractional composition, it is shown that the equivalent diameters of particles of a bubbling and fixed beds that form a partially fluidized disperse system constitute hydrodynamic quantities that depend on the velocity of gas percolation and are determined by the Lyashchenko number. An apparatus of the similarity theory of various modifications has been formulated for modeling transport processes in fully and partially fluidized polydisperse beds, including that restrained by a spherical packing.
