Establishment of a nonuniform mode of fluidization with a uniform distribution of the flow of the cooling medium

Using the principle of the mechanical stability of a system, a criterion for the disturbance of the uniformity of fluidization is obtained and the initial properties of the nonuniform fluidization state of a layer of fine particles close to a distributed grating (the porosity of the dense phase, and the concentration and dimensions of the drops which appear) are considered.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 36, No. 3, pp. 416–425, March, 1978.
