Numerical simulation of two-phase immiscible incompressible flows in heterogeneous porous media with capillary barriers
We present a new version of the sequential discontinuous Galerkin method introduced in [25] for two-phase immiscible incompressible flows in heterogeneous porous media with a discontinuous capillary field. Here, a new implementation of the extended interface condition, that does not use the threshold saturation value at the interface and permits treatment of different residual saturations in di...
متن کاملParallel simulation of two-phase incompressible and immiscible flows in porous media using a finite volume formulation and a modified IMPES approach
In this paper a finite volume method with a “Modified Implicit Pressure, Explicit Saturation” (MIMPES) approach is used to model the 3-D incompressible and immiscible twophase flow of water and oil in heterogeneous and anisotropic porous media. A vertex centered finite volume method with an edge-based data structure is adopted to discretize both the elliptic pressure and the hyperbolic saturati...
متن کاملThe gradient flow structure for incompressible immiscible two-phase flows in porous media
We show that the widely used model governing the motion of two incompressible immiscible fluids in a possibly heterogeneous porous medium has a formal gradient flow structure. More precisely, the fluid composition is governed by the gradient flow of some non-smooth energy. Starting from this energy together with a dissipation potential, we recover the celebrated DarcyMuskat law and the capillar...
متن کاملLattice Boltzmann model for incompressible flows through porous media.
In this paper a lattice Boltzmann model is proposed for isothermal incompressible flow in porous media. The key point is to include the porosity into the equilibrium distribution, and add a force term to the evolution equation to account for the linear and nonlinear drag forces of the medium (the Darcy's term and the Forcheimer's term). Through the Chapman-Enskog procedure, the generalized Navi...
متن کاملNumerical Simulation of Three-Phase Flow in Heterogeneous Porous Media
We describe an efficient numerical simulator, based on an operator splitting technique, for three-phase flow in heterogeneous porous media that takes into account capillary forces, general relations for the relative permeability functions and variable porosity and permeability fields. Our numerical procedure combines a non-oscillatory, second order, conservative central difference scheme for th...
