SFB 1313, A02: Advanced modelling concepts for coupling free flow with porous-media flow

Department of Hydromechanics and Modelling of Hydrosystems

Research project A02 within the Collaborative Research Center (SFB) 1313 "Interface-Driven Multi-Field Processes in Porous Media – Flow, Transport and Deformation" funded by the German Research Fondation (DFG) - Project number 327154368

Description

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, multi-phase, multi-component flow and transport processes at a porous-medium free-flow interface and (iii) investigate the influence of these processes on both the porous medium and free-flow region for various application scales.
