PARTICLES IN CIRCULATING FLUIDIZED BEDS

The boundary conditions for the boundary-value problems 
of longitudinal mixing of particles are substantiated within the framework 
of circulation and diffusion models. These conditions account for 
the influence of the bottom fluidized bed on the process of mixing.
