SFB 1313, C04: Pore-scale and REV-scale approaches to biological and chemical pore-space alteration in porous media

Department of Hydromechanics and Modelling of Hydrosystems

Research project C04 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


Porosity and permeability are two major hydraulic properties that govern flow through porous media. Different kinds of processes can lead to alterations of the pore space which eventually change the hydraulic properties. This project focuses primarily on fluid-solid interfaces that are prone to change as a result of microbial activity. The alterations need to be measured experimentally and interpreted on the scales of interest by means of numerical simulations. It is also required to improve the efficiency of corresponding complex numerical simulation methods.
