✦ Synopsis

A predictive model baaed on the oow ulus flow atmctum has been developed to evaluate the axial voidage profile and internal flow stmctum along the risers of Circulating Fhaidixed 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 fhrx on the axial voidage profile.
