摘要：

A predictive model based on the core-annulus flow structure has been developed to evaluate the axial voidage profile and internal flow structure along the risers of Circulating Fluidized Beds (CFBs). Through comparison with experimental data, the proposed model is shown to be able to qualitatively and quantitatively predict the effect of operating variables such as superficial gas velocity and solids mass flux on the axial voidage profile.
