Automated Symbolic Upscaling: 1. Model Generation for Extended Applicability Regimes

Abstract

Due to the vast spectra of spatiotemporal variations in subsurface processes and geological media, multiscale modeling has remained a cornerstone for analyzing flow and reactive transport beneath the surface Molins & Knabner, 2019;Scheibe et al., 2015). The technical approaches set forth by this paradigm focus on translating the physical dynamics at finer scales (e.g., the pore-scale) to much larger scales where nontrivial behaviors tend to occur. By providing accurate and computationally efficient predictions of such large-scale behaviors, these analysis methods enhance the understandings of phenomena observed in geological engineering and hydrology, such as acidification reactions in carbonate rocks and biogeochemical reactions (
