Several experiments have evidenced the occurrence of saturation overshoots for flows in homogeneous porous media. Such phenomena are ruled out by standard mathematical models, which are based on equilibrium assumptions. In this presentation we discuss nonequilibrium ...

Work carried out in the last decade or so suggests that the simulators for multiphase flow in porous media should include an additional term, namely a dynamic coefficient, as a measure of the dynamic effect associated with capillary pressure. In this work, ...

This paper examines two-phase flow in porous media with heterogeneous capillary pressure functions. This problem has received very little attention in the literature, and constitutes a challenge for numerical discretization, since saturation discontinuities ...

In this study, dynamic response of a circular tunnel embedded in a porousmedium and subjected to a moving axisymmetric ring load is investigated. To avoid treating Biot’s dynamic equations directly, two scalar potentials and two vector potentials are introduced ...

In this study, the frequency domain dynamic response of a pile embedded in a porous medium and subjected to SH seismic waves is investigated. The surrounding porous medium of the pile is described by Biot’s theory, while the pile embedded in the porous medium ...

<p>Assuming a geometrically linear description (small displacements and small deformation gradients) and linear constitutive equations (Hooke&rsquo;s law) the governing equations are derived for two poroelastic theories, Biot&rsquo;s theory (BT) and the Theory ...
