Reflections on the role of chemical osmosis mechanisms on the long-term behavior of a collapsed salt cavity
Published 2022-10-01“…Recent work on chemical osmosis in clay media, motivated by research on the geological storage of nuclear waste in a clay layer, raises questions about the role of this mechanism on the long-term behavior of the system.Based on a bibliographical approach, the article presents a brisk synthesis of the theory of chemical osmosis and discusses its application to the case of clayey rocks which can constitute imperfect membranes capable of generating osmotic pressures.First, the article presents the equations representing the flow of the fluid and the solute transport according to a simplified formulation adapted to the geometry of the system. …”
