Abstract

In this paper we apply the lattice Boltzmann method and an extension to particlesuspensions as introduced by Ladd et al to study transport phenomena and structuringeffects of particles suspended in a fluid near sheared solid walls. We find that a particle freeregion arises near walls, which has a width depending on the shear rate and the particleconcentration. The wall causes the formation of parallel particle layers at lowconcentrations, where the number of particles per layer decreases with increasing distancefrom the wall.
