Semi-resolved CFD–DEM for thermal particulate flows with applications to fluidized beds

, 2020
Particulate flows with heat transfer widely exist in industry including fluidized bed reactor and powder-based 3D printing, and are frequently modeled with CFD–DEM coupled approaches. Recently, we developed a semi-resolved CFD–DEM approach, which bridges

A semi-resolved CFD-DEM approach for particulate flows with kernel based approximation and Hilbert curve based searching strategy

Journal of Computational Physics, 2019
Particulate flow has a wide range of industrial applications and is frequently modeled with coupled CFD–DEM approaches. Herein, we first identified a simulation gap between the resolved CFD–DEM and unresolved CFD–DEM through a size effect study.
