  ongoing joint project with R. Höfer and C. Zeppieri. We study the homoge
 nization of nonlinear Stokes-type problems for incompressible fluids on ra
 ndomly perforated domains. We assume minimal hypotheses on the obstacles d
 istribution\, allowing for clustering and overlapping of perforations. By 
 means of a Γ-convergence result\, we show that\, similarly to the case of
  nonlinear Laplace problems\, there is a critical scale of the obstacles f
 or which an extra term appears in the limiting energy. This extra term may
  be interpreted as an effective drag term due to the homogenized presence 
 of perforations.\n
