Advances in Water Phase Transitions in Porous Media: Bridging Scales and Physics to Understand Hydrological Systems Evolution
Session ID#: 247957
Session Description:
Water in porous media can exist as vapor, liquid, or ice, undergoing complex phase transitions—including evaporation, condensation, freezing, thawing, deposition, and sublimation—within Earth's climate systems. These transitions not only regulate hydrological and mechanical behaviors of porous media but also facilitate heat and mass transfer between the land surface and phreatic zone at the large scale. This session aims to enhance our understanding of multiscale water phase changes in porous media to improve predictive models of large-scale hydrological processes. We welcome submissions spanning all scales, including molecular-scale phase transitions in confined environments; pore-scale freeze-thaw and evaporation-condensation cycles with associated hysteresis and mechanical responses; roles of local chemistry in phase transitions and impacts on species transport; multiphase flow modeling incorporating phase change-driven heat and mass transfer; and large-scale hydrological modeling. Applications may include but are not limited to vadose zone evapotranspiration, snow and firn hydrology, permafrost degradation, and contaminant and nutrient transport.
