Title: Discrete element simulation of dense gas-solid reacting flow
Abstract: Dense gas-solid reacting flow involves complex multiphase flow, heat and mass transfer, and chemical reactions. Computational fluid dynamics-discrete element method (CFD-DEM) simulation has become a promising method to understand and optimize the dense gas-solid reacting systems. Despite its recently rapid advancement and successful applications to a variety of chemical engineering processes, a comprehensive introduction of the theory and applications that underpin the CFD-DEM modelling of dense gas-solid reacting flow has not yet been conducted. In this work, we give the recent progress in the development of CFD-DEM models and their applications to dense gas-solid reacting systems. The sub-models for describing the flow dynamics and thermochemical conversion are firstly presented in terms of numerical algorithms and corresponding implementations from flow to heat and mass transfer and speed-up methods. Then, the recent advancements of CFD-DEM applications in dense gas-solid reacting systems are given, with a focus on chemical engineering processes, e.g., biomass gasification, char combustion, blast furnace ironmaking, and PV pyrolysis.
