Efficiency and Accuracy of Micro‐Macro Models for Mineral Dissolution

S Gärttner, P Frolkovič, P Knabner… - Water Resources …, 2020 - Wiley Online Library
Micro‐macro models for dissolution processes are derived from detailed pore‐scale models
applying upscaling techniques. They consist of flow and transport equations at the scale of …

Numerical investigation of a fully coupled micro-macro model for mineral dissolution and precipitation

N Ray, J Oberlander, P Frolkovic - Computational Geosciences, 2019 - Springer
Mineral dissolution and precipitation alter a porous medium's structure and its bulk
properties. Due to the medium's heterogeneity and lack in dynamic pore-scale …

Strong solvability up to clogging of an effective diffusion–precipitation model in an evolving porous medium

R Schulz, N Ray, F Frank, HS Mahato… - European Journal of …, 2017 - cambridge.org
In the first part of this article, we extend the formal upscaling of a diffusion–precipitation
model through a two-scale asymptotic expansion in a level set framework to three …

Upscaling of a tri-phase phase-field model for precipitation in porous media

M Redeker, C Rohde, I Sorin Pop - IMA Journal of Applied …, 2016 - academic.oup.com
We consider a porous medium with a pore space that is completely filled by three different
phases: two immiscible fluids (say water and oil) and a solid phase. One fluid phase …

Unfolding operator method for thin domains with a locally periodic highly oscillatory boundary

JM Arrieta, M Villanueva-Pesqueira - SIAM Journal on Mathematical Analysis, 2016 - SIAM
We analyze the behavior of solutions of the Poisson equation with homogeneous Neumann
boundary conditions in a two-dimensional thin domain which presents locally periodic …

Derivation and analysis of an effective model for biofilm growth in evolving porous media
