Homogenization of Immiscible Compressible Two-Phase Flow in Porous Media: Application to Gas Migration in a Nuclear Waste Repository

Abstract: This paper is devoted to the homogenization of a coupled system of diffusionconvection equations in a domain with periodic microstructure, modeling the flow and transport of immiscible compressible, such as water-gas, fluids through porous media. The problem is formulated in terms of a nonlinear parabolic equation for the nonwetting phase pressure and a nonlinear degenerate parabolic diffusion-convection equation for the wetting saturation phase with rapidly oscillating porosity function and absolute permeabil… Show more

“…Using these estimates and applying Lemma from , we obtain the following compactness result. Proposition For any x 0 ∈Ω∖ A n , under our standing assumptions the families {}sm,x0εε>0,{}θm,x0εε>0 are compact sets in the space L q ( Y ×]0, T [) for all q ∈[1, ∞ [, where θm,x0ε=defϱg()pm,x0ε+Gg()sm,x0ε()1sm,x0ε.…”

“…Recently, in [7], an existence result has been shown in the case where the densities of each phase depend on the corresponding pressure. This approach is also used in [8,9] to treat a homogenization problem of immiscible compressible water-gas flow in porous media. For miscible and compressible flow, we refer to [10,11] for more details.…”
