Evaporation in porous media is relevant for many engineering processes and for soil cultivation. These processes occur over several scales, where the evolving liquid-gas interface is important to describe the evaporation at the pore scale, while its effect is found on the REV scale. The main goal of this project is to provide a better mathematical description of REV-scale evaporation by accounting for pore-scale processes. The starting point is a pore-scale formulation of the relevant processes and upscaling to derive an effective model at REV scale is performed.
