Abstract:
We consider an initial-boundary value problem describing the process
of filtration of a weakly viscous fluid in two distinct porous media
with common boundary. We prove, at the microscopic level, the existence
and uniqueness of a generalized solution of the problem on the joint motion
of two incompressible elastic porous (poroelastic) bodies with distinct
Lamé constants and different microstructures, and of a viscous
incompressible porous fluid. Under various assumptions on the data
of the problem, we derive homogenized models of filtration of an incompressible
weakly viscous fluid in two distinct elastic or absolutely rigid porous media
with common boundary.
Keywords:
heterogeneous media, periodic structure, Lamé equations,
Stokes equations, homogenization, two-scale convergence.
