Homogenization of a non-Newtonian flow through a porous medium
Abstract:
We consider the stationary incompressible viscous non-Newtonian flow through a porous medium. We assume that viscosity is a nonlinear function of the symmetric velocity gradient, i.e. this nonlinear function is a generalization of the power-law case. We provide a mathematical derivation of the law governing a polymer flow through a porous medium using homogenization. The crucial mathematical tool that we use is two-scale convergence, here adopted for Orlicz setting.
