| 英文摘要 | Complex gas-solid fluidization systems with multiscale dynamic structures have been widely encountered in process industries. Understanding their hydrodynamic characteristics is essential for the proper design and scale-up of such reactors. The energy-minimization multi-scale (EMMS) method provides a general modeling idea for the quantitative characterization of gas-solid heterogeneous systems. In this paper, a concise introduction of the EMMS drag model for coarse-grid continuum simulation was first provided, with emphasis on our recent progress on the improvement and generalization of the drag model. The extension and application of the population balance model (PBM) in quantifying the dynamic evolution of bubbles or clusters in the fluidized beds were then discussed, followed by an overview of the integration of PBM and structure-dependent models. Finally, the application of EMMS theory in predicting the macroscopic steady-state dynamics of complex gas-solid reactors was also reviewed, together with the development of the steady-state EMMS models applicable for various regimes, the construction of generalized operating diagram and the realization of full-loop modeling of gas-solid circulating fluidized bed reactors. 漏 2022 Chemical Industry Press.
