Abstract:

Recent models of partially saturated flow through porous media include dynamic effects in the capillary pressure curves. These lead to partial differential equations of pseudo-parabolic type with multiple nonlinearity and degeneracy. We describe properties and numerical computation of solutions of appropriate initial-boundary-value problems and the upscaling from various types of heterogeneous media. This is joint work with Malgo Peszynska and Son-Young Yi.
