Modelling, Upscaling and Simulation of Dissolution and Precipitation in a Porous Medium with an Evolving Pore-Scale Geometry

Explore the modeling and simulation of dissolution and precipitation processes in porous media with evolving pore-scale geometry in this SIAM Geosciences webinar. Delve into different modeling approaches, from pore-scale to Darcy-scale, using homogenization techniques. Examine the impact of changing pore geometries on medium properties like porosity and permeability. Learn about adaptive multi-scale iterative schemes and their applications. Gain insights into phase field models, direction diffusion equations, and numerical algorithms for simulating these complex geophysical phenomena. Understand the relevance of these processes to critical issues such as soil salinization and geothermal energy production.
