TRANSFER OF MODELING CONCEPTS FOR FLOW AND TRANSPORT PROCESSES IN POROUS MEDIA FROM SUBSURFACE SYSTEMS TO BIOLOGICAL TISSUES

Flow and transport phenomena in porous media are the governing processes in many natural and industrial systems. For the numerical description of these systems their multiscale behavior plays an important role. In one part of the system highly complex flow and transport processes may necessitate an examination of the processes on a fine spatial and temporal scale, while in other parts of the system, physically simpler processes may be examined on coarser scales. The heterogeneous structure of the porous medium itself also shows a high dependence on the spatial scale. Whereas different kinds of heterogeneities predominate on different scales. For these multiscale problems, many modeling concepts have been developed over the last decades. In this presentation, we aim to develop and to discuss the transfer of available modeling concepts for geological and industrial systems to biological tissues. In a comparison study, the similarities of both systems will be presented First simulation results will show the opportunities of the described model transfer. In this context, we will also point out the required assumptions and the difficulties resulting from such a modelin g concept transfer.
