Gradient discretization of hybrid-dimensional Darcy flow in fractured porous media with discontinuous pressures at matrix-fracture interfaces
IMA Journal of Numerical Analysis(2017)
Abstract
We investigate the discretization of Darcy flow through fractured porous media on general polyhedral meshes. We consider a hybrid-dimensional model, invoking a complex network of planar fractures. The model accounts for matrix–fracture interactions and fractures acting either as drains or as barriers, i.e., we have to deal with pressure discontinuities at matrix–fracture interfaces. The numerical ...
