| Abstract: | In this paper we are concerned with modeling single phase flow in a medium with known fractures. In particular we are interested
in the case in which the flow rate in the fractures is large enough to make it appropriate to use Forchheimer’s law for modeling
the flow in the fractures even though the flow in the surrounding domain is such that Darcy’s law is adequate. We describe
a model in which the fractures are treated as interfaces. We also consider the case of intersecting fractures and the case
of nonconforming meshes. |
