Abstract: The transport of particles in two-dimensional self-affine rough channels is investigated through numerical simulations. We show how the average transit time depends on the particle Stokes number as well as on the restitution coefficient controlling the collisions with the walls. More precisely, our results reveal that the particle motion in such irregular channels displays a complex behavior that is characterized by the existence of four distinct transit time regimes. Finally, we also show that this rich behavior is a direct consequence of the local competition between particle-structure (collisions) and particle-fluid (drag) interactions taking place in the system.
