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

A method to determine local mass flux measurements within the riser of a circulating fluidized bed using the rate of impingement of particles on the surface of a piezoelectric pressure transducer is described. Statistically designed experiments with various solids circulation rates and riser gas vel
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
Axial and radial segregation effects due to differences in particle sizes and solids densities were studied in a 0.2-m-dia. riser at gas velocities between 3.5 and 7 m/s and solids circulation rates between 8 and 40 kg/(m2.s). Two bed materials (a quartz sand/iron powder mixture and a quartz sand wi
