摘要

In this work the momentum and energy transfer in a non-saturated flow through a rigid porous matrix is studied. The porous medium is assumed to be homogeneous, rigid isotropic and at rest while the fluid is assumed to be perfect (nonviscous). The existence of gradients of concentration gives rise to a fluid flow which affects the heat transfer in both the solid and the fluid. The porous medium and the fluid will be regarded as continuous constituents of a mixture that will have also a third constituent, an inert gas, assumed with zero mass density and thermal conductivity. The problem to be simulated is mathematically described by a set of four nonlinear partial differential equations that will be solved with the help of a powerful numerical tool.
