Clusters and strands of fine particles as well as voids of elongated and distorted shapes move rapidly in a zigzag manner through the bed. The solids hold-up is quite high (25-35 % by volume) and at the indistinct bed surface, aggregates of particles are continuously ejected into the freeboard. Turbulent fluidization is often employed in industrial fluidized-bed reactors because of efficient gas-solid contact, rapid heat and mass transfer and limited axial mixing of gas. Although it accounts for most commercial applications of gas-solid fluidization, the turbulent fluidization has received far less attention than the adjacent flow regimes of bubbling (or slugging) and fast fluidization. A number of empirical correlations are presented for prediction of the range of turbulent fluidization. Turbulent beds exhibit non-uniform distributions of voidage/solids holdup in both axial and radial directions"@en . "CZ - \u010Cesk\u00E1 republika" . "556;562" . "Svoboda, Karel" .
