摘要: Abstract The continuum approach of the Eulerian finite element method (FEM) is used to investigate complex granular flow and mixing in a cylindrical bladed mixer (CBM). verified by comparing various features solids reproduced FEM, such as formation heaps, recirculating around blades spatial distributions velocities, with those from DEM. A convective model based on FEM proposed describe evolution pattern well index. It shown that results can agree However, due lack physical law particle diffusion random walk percolation, simulated index only qualitative implication at present. While much work will be needed future, allows investigation general behaviours large-scale mixers serve sound basis for ultimately establishing predictive capability mixing.
