Axial solid velocity, solid volume fraction, and solid shear viscosity were computed in the riser of a circulating puidized-bed reactor using a two-phase 2-0 computational fluid dynamic model. The time-averaged model predictions agree well with the experimental data of Miller and Gidaspow (1992). Th

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
