A 3-D model based on computational fluid dynamics was developed for studying the effects of inlet gas velocity on the
operation of multi-zone circulating reactors (MZCRs) from a hydrodynamic viewpoint. The system was modeled by the two
fluid model (TFM) based on the kinetic theory of granular flow (KTGF). The re-normalization group (RNG) k-ε model was
applied for implementing the turbulency. Effect of inlet gas velocity on overriding parameters, such as pressure drop and
solid volume fraction, was studied. The results showed a limitation in both increasing and decreasing the inlet gas velocity.
Therefore, operating at a proper range of inlet gas velocity is recommended for MZCRs.
