A01: Molecular detail in ﬂuid simulations: Density Functional Theory within component and momentum balances(Universität Stuttgart) Mar 17, 2021 Most porous materials involve non-uniform solid surfaces. This project applies and further develops classical density functional theory (DFT) to study how chemical and structural heterogeneities of the porous material alter adsorption isotherms, wetting behaviour, surface tension...
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,...
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...
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...
B02: Fracturing porous solids with pore content(Universität Stuttgart) Feb 3, 2021 We describe fracturing porous solids with arbitrary pore content by two basic ingredients, the macroscopic Theory of Porous Media and the phase-field approach to fracturing. Initially, the solid is treated as a brittle elastic material that is permeable for arbitrary fluids in th...
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...
B04: Hybrid discrete-continuum models for fractured porous media: model choice and random field/network generation(Universität Stuttgart) $B04: Hybrid discrete-continuum models for fractured porous media: model choice and random field/network generation logo$ Apr 22, 2020 Fractured porous media are geometrically very complex. There are many competing model concepts to represent their structure in flow simulations; these models differ drastically in their level of geo¬metric detail and in their level of simplification and abstraction. Systematicall...
