Multiscale Modelling of Convective Mixing in Confined Porous Media
Offered By: PoreLab via YouTube
Course Description
Overview
Explore the multiscale modelling of convective mixing in confined porous media through this 45-minute lecture by Dr. Marco De Paoli from the University of Twente and TU Wien. Delve into the relevance of mixing in porous media for various geophysical subsurface flows, including water contamination, petroleum migration, sea ice formation, and geological carbon dioxide sequestration. Examine how dispersed solutes induce density differences, leading to convective motions that drive fluid flow. Understand the multiscale nature of these systems, where diffusion controls solute mixing at the pore scale while large-scale convective structures enhance overall mixing. Discover recent findings and modelling strategies for convective porous media flows, including pore-scale, Darcy-scale, and gravity current simulations, as well as Hele-Shaw and bead pack experiments. Gain insights into simple physical models explaining these phenomena and discuss the limitations of proposed approaches in this comprehensive exploration of confined porous media dynamics.
