Abstract:
We consider the homogenization of some viscous incompressible non-Newtonian flows in perforated domains. With certain general assumptions on the nonlinear stress tensor, we show the limit system is the Darcy`s law for the case of `small holes`, and system remain unchanged for the case of `large holes`. Quantitative convergence rates are also given for both the velocity field and the pressure.
