Item Description: A general algorithmic framework is established for numerical simulations of three-dimensional fluid–particle interaction problems with a large number of moving particles in turbulent flows using a combined lattice Boltzmann method (LBM) and discrete element method (DEM). The main computational aspects comprise the LBM for fluid flows, the incorporation of a large eddy simulation-based turbulence model for turbulent flows, the moving boundary condition for hydrodynamic interactions between fluid and moving particles, and the discrete element modelling of particle-particle interactions. A laboratory model of vacuum dredging systems for mineral recovery is employed to assess the solution accuracy of the proposed methodology.
