New hybrid CPU-GPU solver for CFD-DEM simulation of fluidized bedsAbstract The algorithm and implementation details of a new parallel CFD-DEM solver that uses both CPU and GPU resources for computations are presented in this study. The new solver supports complex geometries, various shapes of mesh, converges at very high fluid…

Simulation of granular mixing in a static mixer by discrete element methodAbstract Mixing of solids in static mixers with different geometries was studied using discrete element method (DEM) simulations. The DEM code was validated by comparing the simulation results with experimental data for a static mixer with 180° Kenics elements.…

Simulation of pellet coating in Wurster coatersAbstract A combination of computational fluid dynamics (CFD), discrete element method (DEM), and discrete droplet method (DDM), i.e., a CFD-DEM-DDM model, was developed to simulate coating of pellets in a Wurster coater. The model equations were implemented in parallel using an approach that uses…
