Abstraet--A new approach to the modelling of gross gas-solids flow through the riser in a circulating fluidized-bed system is proposed in this paper. This approach differs from the previous ones, which are found to be theoretically incorrect based on a fundamental analysis of the riser process hydro
Radial solids velocity profiles were computed on seven axial levels in the riser of a high-flux circulating fluidized bed (HFCFB) using a twophase 3-D computational fluid dynamics model. The computed solids velocities were compared with experimental data on a riser with an internal diameter of 76 mm
Results of detailed experimental measurements of solids mass flux profiles in circulating tfuidized-bed risers of internal diameter 0.152 and 0.305 m are described. The ranges of superficial gas velocity and mean solids mass flux used were 3-5 m s-1 and 2-111 kg m ' s I, respectively, and the solids
