## Abstract A new wavelet‐threshold criterion was developed to distinguish the cluster and the void phases from the transient solids holdup/concentration fluctuation signals when measured in a 108 mm‐i.d. × 5.75 m‐high circulating fluidized bed with FCC particles (d~p~ = 78 μm, ρ~p~ = 1,880 kg/m^3^

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

The characteristics of heat transfer were studied in both a gas-solids concurrent downflow fluidized bed (downer) and a gassolids concurrent upflow fluidized bed (riser) with FCC particles. The radial and axial distribution profiles of the heat transfer coefficient between a suspended surface and th
