Porous media are everywhere. From the human body, via important technical applications – such as the fuel cell – to huge environmental systems. Porous media are fascinating, because many related topics still haven’t been explored. It is great that we can combine fundamental questions and applications in our research. Within SFB 1313 (Collaborative Research Center), we research flow, transport and deformation in porous media for a wide variety of problems. In my work, I’m trying to optimize the concept of fuel cells so as to make a contribution to sustainable mobility. We are interested in the fluid transport through the single porous layers. We are working on very small scales, that’s why we need to simplify the methods in order to put the whole thing on a scale where we can translate the data into feasible models. We are trying to generate a model that allows us to predict the propagation and hardening of bone cement in osteoporotic vertebrae. To record the pore structure, we use micro-CT images of osteoporotic vertebral bodies. These data are used in our modelling and simulations in order to make predictions. These predictions are particularly important when it comes to planning a surgical procedure where we want to reduce the risk of complications. What’s special is that these questions can only be answered and solved in an interdisciplinary and international team. And that is just what SFB 1313 provides. From our base in Stuttgart, we work together with our international partners – from doctoral and post-doctoral researchers to professors, from technicians to managers. Together, we are able to tackle and solve these complex processes in our team.
