RESUMO

This paper is concerned with the migration of particles in a dense slurry flow, which is a mixture, consisting of more or less spherical particles immersed in a Newtonian fluid. The particles are rough, and we study their interaction in the lubrication limit, both analytically and in a numerical simulation. The analytical results are replicated in the simulation: structures form in the low shear rate region when the particle interaction does not involve a substantial repulsive element, they disappear when a repulsive elastic interaction is implemented.
