| Zusammenfassung |
| When a fluid infiltrates into an unsaturated soil or when a wet porous medium dries, the different driving forces of the infiltration or drying processes can lead to an unstable growth of the water-gas interface or to self-stabilizing behavior. The free flow - porous media interface processes have a strong influence on the above mentioned flow and transport mechanisms.
Up to now, the coupling of free flow with porous media flow has been often considered only for single-phase systems. We extend this classical concept to two-component non-isothermal flow with two phases inside the porous medium and a single phase in the free flow region. With this, our model also takes evaporation and condensation processes into account.
We will discuss the influence of the free flow - porous media interface on evaporation and water distribution and present comparisons of our concept with classical concepts. |
