摘要：

A mathematical model is proposed to analysis low-velocity gas-powder flow in a packed bed. The model, as an extension of the two-fluid model, consider the interactions between gas, powder and packed particles, as well as the static and dynamic holdups of powder. What's more, the sticking rate and departing rate of powder, which are derived from the filtration mechanisms, are also included in the powder phase's continuity equation. The validation of the present model is performed by comparing the simulated results with the previous experimental. On this basis, the flow characteristics of low-velocity gas-powder flow in a packed bed with lateral inlet are analysed, and the effect of gas velocity and powder mass flux on static holdup of powder have also been investigated. © W.
