This paper investigates the evolution of the solid component of a protoplanetary disk in which the gas flows in a non-axisymmetric way due to persistent large-scale structures such as giant vortices or spiral patterns. The dynamics of the particles, submitted to the gravity of the central star and to the gas drag, is studied through numerical integrations of the motion equations. Particles, following their size, are found to be radially confined by the flow patterns. This dynamical behavior, which differs significantly from the standard radial decay in the axisymmetric case, could make easier the formation of the planetesimals.
