Collaborative Research Centers

Collaborative Research Centers (CRC) are, in addition to transregios of the German Research Foundation (DFG), among the flagships of the German scientific landscape.

Computer simulations allow us to answer questions about the properties of materials, causes of fracturing, machine process flows or biochemical processes. But, to understand the macro world, we first need to grasp it at the small and smallest scales. This is the principle to which the researchers of CRC 716 have dedicated themselves to investigate the smallest particles in nature and technology. With computers, they reconstruct the behavior of atoms and molecules in the quest for answers to current scientific problems.

To this end, we have teams from the natural and engineering sciences as well as computer science working closely together. They develop suitable models for describing the processes in realms that are invisible to the eye. In the process, they seek to make it possible to calculate a maximum of information, long time frames and complex problems on presently available computer architectures in order to create intelligible pictures of the particle world.

The Collaborative Research Center (CRC) 1313 has set itself the target of developing a fundamental understanding of how the interfaces – for example between two fluids or between the fluid and a solid material – influence flow, transport and deformation in porous media. On the one hand it should be quantified which influencing factors like pore geometry, the heterogeneity and cracks in the porous medium have on the dynamics of the flow processes. On the other hand mathematical and numerical models should be developed with which the impacts of processes that take place on very many small scales can be integrated into flow simulations.

How liquids or gases (fluids) spread in porous media, for example in rocks, and to which deformations this leads plays a role in very many fields of application. Examples of this are the optimisation of fuel cells, the storage of carbon dioxide or methane underground, the prediction of landslides after heavy rain or the transport of medicaments in human tissues.

The fundamental understanding of droplet dynamics is the critical prerequisite to the prediction of natural processes and the optimization of technical systems. Many of these processes happen under extreme ambient conditions - e.g. high pressure or extreme temperatures - and can already be found in technical applications, despite the absence of fundamental knowledge. This is exactly where the new Collaborative Research Center focuses on. The goal is to gain a profound physical understanding of the essential processes. This understanding is the basis for new ways of analytical and numerical descriptions. Thereby, an improved prediction of large systems in nature or in technical applications shall be possible.
