AB - The present study is devoted to solving the problem of seismic and acoustic wave propagation in the porous media for composite domains. For simplicity, simple geometry was selected, where domain Ω in consideration consists of three different domains Ωk,k=1,2,3 with different physical and geometrical properties. The wave propagation in the solid skeleton Ω_s of Ω is governed by the Lame's equations. The fluid dynamics in the liquid domain Ωf= ⋃3k=1Ωf,k is governed by the Stokes equations. To model the geometry, we postulate that there are two small parameters: the dimensionless size of pores ε and the dimensionless size of fractures δ and ε≤δ, where ε=l/L is the dimensionless pore size, l is the average size of pores. Domains Ωf,1 and Ωf,3 have the ε-periodic structure and the domain Ωf,2 has the δ-periodic structure with ε=δr,0SN - 2576-9898
