Part A: 

Processes at fluid–solid interfaces fundamentally control mass transfer, reaction kinetics, and permeability evolution in geological materials.

This session focuses on the modeling and mathematical methods for pore-scale mechanisms including fluid-solid element exchange, moving boundary problems during dissolution and precipitation, and fluid liberation from hydrous minerals during metamorphic reactions. Particular attention is given to fluid flow in low-porosity systems and transport in confined geometries, where capillarity, surface energy, and reactive interface dynamics dominate.

Part B: 

Large-scale geodynamic behavior emerges from the interplay between deformation, rheology, and multiphase flow. This session addresses the modeling and mathematical methods with a focus on mechanical aspects of fluid-bearing rocks, including viscous, plastic, and brittle regimes of large scale deformations. This includes two-phase flow systems with dynamically evolving porosity-permeability relationships and feedbacks between compaction, dilation, and fluid pressure.
