Abstract


A lattice Boltzmann method is presented which enables the direct numerical simulation of particle-laden flows. It applies a fluid-solid coupling technique based on the momentum exchange method to represent geometrically fully resolved particles of arbitrary shape. The test case of a single moving sphere allows an in-depth evaluation of the algorithm. The method is fully parallelizable and yields results with an accuracy comparable to classical CFD simulations. This forms the basis for simulations of complex systems involving several thousand particles like the sediment transport in river beds.A lattice Boltzmann method is presented which enables the direct numerical simulation of particle-laden flows.
