Nonlinear two phase fluid flow through a porous medium in presence of a well

摘要

We study a flow of fresh and salt water in a two dimensional axially symmetric coastal aquifer with a well on the central axis. The flow is governed by a nonlinear Darcy's law. We also show the behavior of the solution when the out flow of salt water at well goes to 0. (author) 33 refs, 3 figs
