Numerical investigation on the role of discrete element method in combined LBM–IBM–DEM modeling.

Highlights: [•] A novel combined LBM–IBM–DEM scheme is presented. [•] The method combines the good features of the LBM and the IBM by using two meshes. [•] The collision rules enable particles to be specified by material properties. [•] The method eliminates the need for determination of artificial parameter. [•] The collision scheme is important in the particulate flow simulation. [ABSTRACT FROM AUTHOR]
