Abstract

Mixed finite element methods are analyzed for the approximation of the solution of the system of equations that describes the flow of a single-phase fluid in a porous medium in ℝ^d, d ≤3, subject to Forchhheimer's law - a nonlinear form of Darcy's law. Existence and uniqueness of the approximation are proved, and optimal order error estimates in L ^∞(J; L²(Ω)) and in V(J; H(div; Ω)) are demonstrated for the pressure and momentum, respectively. Error estimates are also derived in L^∞J; L^∞(Ω)) for the pressure.
