Numerical simulation of one-dimensional flows through porous media with shock waves

This work studies an unsaturated flow of a Newtonian fluid through a rigid porous matrix, using a mixture theory approach in its modelling. The mixtur e consists of three overlapping continuous constituents: a solid (porous me dium), a liquid (Newtonian fluid) and,an inert gas (to account for the mixt ure compressibility). A set of two nonlinear partial differential equations describes the problem, which is approximated by means of a Glimm's scheme, combined with an operator splitting technique.
