“…Similarly, coal has different densities due to its different mineral compositions [47][48][49][50][51]. Coincidentally, the densities between long flame coal [47] and biomass [52] (e.g., sugarcane bagasse, maize stalk, etc.) are similar.…”

“…[37,53]. In addition, the DEM time step was set to 1 × 10 − 5 s to ensure the stability of the numerical simulation, which was equivalent to 15% of the Rayleigh time [37,52]. The total number of spherical and cylindrical particles is 22,000, where the details of model validation and simulation parameters are given in Appendix B and Table 1, respectively.…”

“…The solid particle motion, namely, the velocity, position, angular velocity and angle, could be updated using time integration schemes (Fraige and Langston, 2004;Danby et al, 2013;Kruggel-Emden et al, 2008). A semi-implicit finite volume method that uses a staggered grid was used to discretize the incompressible fluid flow.…”

In this paper, we describe an industrial application of the discrete element method (DEM). The DEM has been applied to various powder systems thus far and therefore appears to be an established approach. However, it cannot be applied to many industrial systems because of several critical problems such as modeling of large-scale simulations, complexly shaped wall boundaries and free surface fluid flow. To solve these problems, novel models were developed by our group. A coarse-grain DEM model was developed for large-scale simulations, a signed distance function-based wall boundary model was developed for complexly shaped walls and a DEM-moving particle semi-implicit method was developed for solid-liquid flow involving a free surface. The adequacy of these models was demonstrated through verification and validation tests. Our approach shows promise in industrial applications.
