| 英文摘要 | Counter-current gas-solid downer reactors can be used to prepare necessary high solids concentrations for high heat and/or mass transfer processes. However, the downward particle movement is much likely to be prevented by an upward gas flow, which can be named as so-called 'flooding' phenomenon. The energy-minimization multiscale (EMMS) theory has been shown to be capable of capturing multiscale heterogeneous structures in gas-solid systems, and hence is further utilized to simulate counter-current gas-solid downward flow in this article. The formulated model characterizes well the axial hydrodynamics and its parametric effects in counter-current gas-solid downers. Flooding gas velocity can be further determined from the calculation results, which is consistent with the empirical correlation qualitatively. |
