This paper describes computational models for particle-laden flows based on a fully resolved fluid-structure interaction. The flow simulation uses the Lattice Boltzmann method, while the particles are handled by a rigid body dynamics algorithm. The particles can have individual non-spherical shapes, creating the need for a non-trivial collision detection and special contact models. An explicit coupling algorithm transfers momenta from the fluid to the particles in each time step, while the… CONTINUE READING
