Our SFB 1313 researchers Rainer Helmig, Holger Class, and Martin Schneider from the University of Stuttgart as well as our former SFB 1313 guest Costanza Aricò from the University Palermo (Italy) jointly organized a mini symposium during the Engineering Mechanics Institute International Conference 2023 (EMI IC 2023). The conference took place at the University of Palermo from 27 to 30 August 2023.

Abstract
Transport phenomena of coupled free flow and porous-medium flow occur in several environmental, industrial and biological applications. These include surface and groundwater flow, contaminant transport from lakes by groundwater, soil evaporation, fuel cells, oil filters, passive flow control devices, food drying, blood flow in vessels and tissue, or transport of therapeutic agents.
When modelling such applications, physical processes occur over several spatial and temporal scales. Typically, averaged continuum models, based on the representative elementary volume (REV) approach, are used for meso- and macro-scale simulations to overcome the high computational effort required by direct numerical simulations (DNS) when modelling these types of systems on the pore-scale. However, this leads to a loss of detailed pore-scale processes which might strongly affect the global system behavior. Pore network models represent an attractive tool for understanding and predicting meso-scale phenomena by abstracting pore geometries into pore bodies and pore throats, allowing to efficiently perform pore-scale simulations
This mini-symposium is mainly devoted to provide an insight into the physical, mathematical and numerical modelling of coupled free flow and porous-medium flow systems related to recent theoretical, numerical and experimental findings and challenges. Furthermore, recent numerical and mathematical developments related to the REV-scale description of averaged or upscaled pore-scale phenomena using effective REV models shall be addressed and discussed within this mini-symposium.
About the EMI 2023
The EMI international conference was organized and led by Massimo Midiri and Antonina Pirrotta from the University of Palermo.
The conference provided a forum for researchers and practitioners, where the fundamental and applied advances in engineering mechanics were on displayed. At the conference, the latest discoveries in the field of engineering mechanics were presented. The program included own contributions at topical sessions, distinguished plenary lecturers and discussions, panels and networking events to advance engineering mechanics education, research and practice. To support attending PhD students, the special junior sessions took place. These chairs were organised by young assistant professors and PhD student's speakers only.
