Evaporation from a Porous Medium in the Presence of Salt Crystallization

Conference paper
Part of the NATO Science for Peace and Security Series C: Environmental Security book series (NAPSC)


The interplay between salt transport, crystallization and evaporation from a porous medium is a topic rich in interesting open problems. This is illustrated through the consideration of a few of them from experiments with model porous media. We notably discuss the factors controlling the localization of crystallization spots at the evaporative surface of a porous medium and the impact of surface crystallization on evaporation kinetics.
