Abstract:  In this paper three regions found experimentally for the expansion of nonuniformly fluidized beds are characterized. A theoretical model of the nonuniformly fluidized bed in the system gas —particles is described and an equation is derived for the relative expansion of bed. The values of relative expansions calculated from this equation are compared with the experiment in the system air—particles and with the values calculated according to the equation put forward by Pyle and Harrison [1]. Our equation is in better agreement with experiment than the equation of Pyle and Harrison.
