Résumé

Drying of porous media in the presence of salt is a very common phenomenon with many applications but it is not totally understood so far. Some experiments that recently appeared in the literature have shown that the kinetics of drying not only strongly depends upon the quantity of precipitated salt but also upon the form in which the salt precipitates. In this paper, a coupled multiphase model that is capable of describing the different drying kinetics taking into account the different efflorescence formations is presented. The model is then validated through two different experimental campaigns on drying in presence of NaCl solution. © 2017 Elsevier Ltd
