KEYNOTE: CFD-DEM Modeling of Gas-Solid Reacting Flow (rCFD-DEM): From New Approaches to Industry Applications

Computational fluid dynamics-discrete element method (CFD-DEM) has become a promising method to understand and optimize dense gas-solid reacting systems at the particle scale, yet the accuracy and efficiency still need to be improved for industry applications. In this work, a reactive CFD-DEM (rCFD-DEM) was developed, combining flow hydrodynamics, heat transfer, chemical reactions. A smooth method and a coarse-grained method were integrated to achieve high resolution and high efficiency, respectively. Two case studies are used for demonstrating that these new developments indeed advance the CFD-DEM modelling of fluid-solid reacting flows.
