A model of wave propagation in homogenized Biot medium with dual porosity
Original language description
We describe a macroscopic model of waves propagating in fluid-saturated periodic media with dual porosity. At the mesoscopic level, the fluid motion in deforming elastic skeleton is governed by the Biot-Darcy model extended by inertia terms. In this paper we deal with upscaling the Biot-Darcy model from the mesoscopic level, where large contrasts in the permeability and the poroelastic coefficients are considered. The two-scale homogenization method is used to obtain a macroscopic model. This model is an extension of previously studied problems with either rigid skeleton part, or deformable Biot medium without large contrasts in material properties.
