Abstract: We study the classical steady Stokes equations with homogeneous Dirichlet boundary conditions. We work in a 3-D domain which contains solid obstacles, two-periodically distributed with period $\E$ (respectively $\E^{2}$), where $\E$ is a small parameter. Our aim is to study the asymptotic behaviour, as $\E\arr 0$. We use the 3-scale convergence for getting the 3-scale limit problem. The problem obtained is a three-pressures system.
