Résumé
In this paper, we consider the Stokes equations in a perforated domain. When the number of holes increases while their radius tends to 0, it is proven in Desvillettes et al. [J. Stat. Phys. 131 (2008) 941{967], under suitable dilution assumptions, that the solution is well approximated asymptotically by solving a Stokes{Brinkman equation. We provide here quantitative estimates in L p -norms of this convergence.
