## Computation of Flow Patterns in Circulating Fluidized Beds Flow regimes of dense-phase vertical pneumatic transport of solids, referred to in the literature as circulating fluidized beds, have been computed using a generalization of the Navier-Stokes equations for two fluids. In the less dense
The intermittent flow in a circulating fluidized bed is shown to possess a multifractal character. The voidage signals at different solids concentrations and radial positions are characterized by defining an intermittency measure selected from a hierarchy of multifractal exponents. The intermittency
A predictive model baaed on the oow ulus flow atmctum has been developed to evaluate the axial voidage profile and internal flow stmctum along the risers of Circulating Fhaidixed Beds (CFBs). Through comparison with experimental data, the proposed model is shown to be able to qualitatively and quant
