Numerical approximations are considered for a mathematical model for miscible displacement influenced by mobile and immobile water. A mixed finite element method is adopted to give a direct approximation of the velocity, the concentration in mobile water is approximated by an alternating direction Galerkin finite element method combined with the method of characteristics and the concentration i...
Asymptotic Behavior of the Solutions of an Elliptic-parabolic System Arising in Flow in Porous Media
We study the asymptotic behavior, with respect to high Péclet numbers, of the solutions of the nonlinear elliptic-parabolic system governing the displacement of one incompressible fluid by another, completely miscible with the first, in a porous medium. Using compensated compactness techniques, we obtain the existence of a global weak solution to the nonlinear degenerate elliptic-parabolic syst...
The effect on the transport properties of fractures of a relative shear displacement ~u of rough walls with complementary self-affine surfaces has been studied experimentally and numerically. The shear displacement ~u induces an anisotropy of the aperture field with a correlation length scaling as u and significantly larger in the direction perpendicular to ~u. This reflects the appearance of l...
