Evaporation-driven density instabilities in saturated porous media(Universität Stuttgart) Jul 18, 2022A05: Pore scale formulations for evaporation, and upscaling to REV scale
Eigenvalue problem solver for evaporation-driven density instabilities in saturated porous media(Universität Stuttgart) Mar 29, 2022A05: Pore scale formulations for evaporation, and upscaling to REV scale
Code for effective heat conductivity in thin porous media(Universität Stuttgart) Jun 14, 2021A05: Pore scale formulations for evaporation, and upscaling to REV scale
A03: Development of interface concepts using averaging techniques(Universität Stuttgart) Mar 16, 2021 New, more general interface conditions are required to couple free-flow and porous-medium systems since traditional coupling concepts provide reliable results for simplified cases only. Averaging theory is a powerful mathematical tool that can be applied to derive such conditions...
D02: Parallel numerical coupling methods for interface problems(Universität Stuttgart) Mar 16, 2021 The aim of the project is to provide technical and numerical methods for the coupling of free flow and porous-media flow at the REV (representative elementary volume) scale. This involves the development of sophisticated methods in three basic coupling components: (i) iterative s...
C02: Upscaling of pore-scale processes involving microstructural evolution(Universität Stuttgart) Mar 8, 2021 Processes like multi-phase flow and reactive transport in porous media are encountered in many engineering applications. Such processes occur and interact on different scales and in complex domains. Particularly challenging is the case when evolving interfaces are encountered on...
Upscaled equations for two-phase flow in highly heterogeneous porous media: Varying permeability and porosity(Universität Stuttgart) Feb 23, 2021A05: Pore scale formulations for evaporation, and upscaling to REV scale
A05: Pore scale formulations for evaporation, and upscaling to REV scale(Universität Stuttgart) Feb 23, 2021 Drying and evaporation in porous media is relevant for many engineering processes and for soil cultivation. These processes occur over several scales, where the evolving liquid-gas interface is important to describe the evaporation at the pore scale, while its effect lies on the...
B03: Heterogeneous multi-scale methods for two-phase flow in dynamically fracturing porous media(Universität Stuttgart) $B03: Heterogeneous multi-scale methods for two-phase flow in dynamically fracturing porous media logo$ Jan 26, 2021 The propagation and bifurcation of fractures in fluid-filled porous media depends on the likewise inter-related flow in the pore space and on the mechanical displacement field in the solid matrix. Assuming that fractures cannot be homogenised but persist on a continuum-mechanical...
A02: Advanced modelling concepts for coupling free flow with porous-media flow(Universität Stuttgart) Jan 13, 2021 Exchange processes across a porous-medium free-flow interface occur in a wide range of environmental, technical and bio-mechanical systems. The primary objectives of this project are to (i) analyse and improve the theory, as well as (ii) offer solution methods for non-isothermal,...
