Mechanics of Fluid Flow through a Porous Medium
By a porous medium we mean a material consisting of a solid matrix with an interconnected void. We suppose that the solid matrix is either rigid (the usual situation) or it undergoes small deformation. The interconnectedness of the void (the pores) allows the flow of one or more fluids through the material. In the simplest situation (“single-phase flow”) the void is saturated by a single fluid. In “two-phase flow” a liquid and a gas share the void space.
