O článku:
A three-dimensional numerical simulation of particle motion in a pipe with a rough bed is presented. The
simulation based on the Lattice Boltzmann Method (LBM) employs the hybrid diffuse bounce-back approach to model
moving boundaries. The bed of the pipe is formed by stationary spherical particles of the same size as the moving
particles. Particle movements are induced by gravitational and hydrodynamic forces. To evaluate the hydrodynamic
forces, the Momentum Exchange Algorithm is used. The LBM unified computational frame makes it possible to simulate
both the particle motion and the fluid flow and to study mutual interactions of the carrier liquid flow and particles and the
particle–bed and particle–particle collisions. The trajectories of simulated and experimental particles are compared. The
Particle Tracking method is used to track particle motion. The correctness of the applied approach is assessed.
