Sustainable and interdisciplinary

Collaborative Research Centers and Research Training Groups

Collaborative Research Centers (CRC) and CRC/Transregios (CRC-TRR) of the German Research Foundation (DFG) are the flagships of the German science landscape. The University of Stuttgart is the lead university for six of these multi-million Euro funded institutes and is a participant in others.

Collaborative Research Centers link researchers from the most varied speciality fields and disciplines. Pictured here is a bionic structure from CRC-TRR 141.

In the Collaborative Research Centers (CRC), sustained by DFG for up to twelve years, researchers collaborate on interdisciplinary, challenging, and costly research projects. CRCs that are permanently located in one university are differentiated from the so-called Transregios (CRC-TRR) that are spread over several university locations.

At present, three Collaborative Research Centers and three Transregional Collaborative Research Centers are housed at the University of Stuttgart. Besides, the University has projects in three additional CRC and three Transregios. Added to this University Stuttgart is speaker in four DFG Research Training Groups and we have two DFG Priority Programs as well as numerous Research Units.

The CRC 1244 "Adaptive envelopes and structures for the constructed environment of tomorrow" deals with the question of how to create more living space with less materials in the face of growing world population and shrinking resources. The use of  adaptive elements in load-bearing structures, envelope systems, and interior works makes it possible to precisely change the structural and building-physical characteristics of materials and construction elements so that they ideally adapt to various kinds of loads. This has many advantages: load-bearing structures can be produced with less material and energy usage. In the field of buliding envelopes the adaptive elements promote energy efficiency and improve the quality of stay inside the buildings - an important prerequisite for an improvement of the user's physical and mental well-being. Besides the static-constructive and building-physically relevant opportunities and effects, the integration of adaptive elements also enlarges the scope of drafting and design in architecture.

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.

Spokesperson: Prof. Bernhard Weigand, Institute of Aerospace Thermodynamics 

Droplets have a key role in many areas of nature and technology. Gaining a fundamental understanding of droplet dynamics processes is crucial for improving technical systems or predicting natural processes. Many of these processes take place under extreme environmental conditions and are already applied in technical systems despite a lack of fundamental knowledge. This is precisely where the Transregio “Droplet dynamics under extreme ambient conditions” picks up. The goal is first to gain a profound physical understanding of these processes, then show how to describe them analytically and numerically and find ways to implement them. This is expected to lead to improved prediction of larger natural systems or technical applications..

Following on the first funding phase of CRC-TRR 75 in which the focus was on fundamental processes of single droplets, the current second phase concentrates on small droplet groups and droplet clusters all oriented to the selected lead examples.

Spokesperson: Prof. Jan Knippers, Institute of Building Structures and Structural Design

Building the way nature does it: Transregio 141 opens a new avenue to design and construction in architecture. It links the competencies of the University of Stuttgart in the fields of lightweight construction and simulation techniques with the focus of partner Universities of Freiburg and Tuebingen in biology, physics, and the geosciences. The goal is to develop multi-functional, adaptable structures that are simultaneously ecologically efficient and also far exceed the limits of conventional structural design. An important characteristic of natural structures is their multi-layered, hierarchically structured and locally differentiated combination of a few basic molecular components. These lead to multiple networked functions. Recent developments in computer-based modeling, simulation, and production offer new options for more closely analyzing these principles and for transferring them to building construction and other technological areas. Our researchers aim not only to improve technical performance but also focus on the ecological characteristics of natural structures, particularly the effective use of limited resources and their closed materials cycles.

Spokesperson: Prof. Daniel Weiskopf, Visualization Research Center

Do images get the information they contain across to the observer? How much effort is required to extract it? What possibilities do new interaction techniques offer? CRC/Transregio 161 focuses on visual computing, that is, the computer-aided processing and presentation of pictorial information. The joint project is carried out by the Universities of Stuttgart and of Constance; the Max-Planck-Institute of Biological Cybernetics in Tuebingen is also a participant.

Subsumed in the “visual computing” title are numerous applications from research and industry as well as from individuals such as the visualization of measurement data or simulations, virtual maps and tours or computer-generated movie scenes. Information scientists from various disciplines collaborate with engineers and psychologists on new technologies for simplifying the representation and processing of the steadily growing masses of data and for further improving the quality of computer-generated images. The goal of the approx. 40 participating scientists is to make the quality and precision of existing as well as new visual computing methods measurable, determinable and adaptable to the needs of different applications and users.

CRC-TRR 40 has scientists at the Universities of Aachen, Braunschweig, Munich and Stuttgart focusing on those components of rocket-propelled space transportation systems that are exposed to extremely high loads and temperatures: the combustion chamber, the nozzle, and the aft body. Structure cooling and flow-structure correlation are also subjects of detailed research in order to improve currently deployed systems.

The projects housed at the University of Stuttgart specifically investigate direct numerical simulation of effusion cooling and new, innovative cooling methods for rocket combustion chambers. Also being investigated is turbulent spray combustion in rocket combustion chambers and droplet vaporization near the critical point and under supercritical conditions.

A decisive feature of current developments is that more and more of the abstract concepts of pure mathematics are made constructive, with interdisciplinary methods playing a significant role. The TRR 195 aims at taking a leading role in driving these developments: In the five core areas listed below, it will provide the computational open source infrastructure for years to come; it will create vast amounts of data important to the mathematical community; and it will exploit the infrastructure and data to solve fundamental mathematical problems.

Sub-projects of the University of Stuttgart:
Prof. Guido Schneider, Institute of Analysis, Dynamics and Modelling

The goals of this Collaborative Research Center include analytically understanding wave propagation under realistic conditions, modeling them numerically and also ultimately controlling them. The fundamental methodological approach is one of integrated mathematical analysis and numerics. The focus of Prof. Schneider’s contribution to this work is approximation using amplitude equations. It finds application in waterwaves or non-linear optics and is used in cases when direct numerical simulation is not feasible due to the multiscale character of the problems under consideration.

Sub-projects of the University of Stuttgart: Prof. Dr. Wolfgang Nowak, Institut of Modelling Hydraulic and Environmental Systems, Stochastic Simulation and Security Research for Hydro Systems

The CRC "CAMPOS – Cycle of matter in drainage areas: Metabolization of pollutants on the landscape scale“ examines the transport and turnover of pollutants in the spacious and long-term process chains that are predominant in nature. By using innovative monitoring systems as well as numerical landscape models the CRC wants to create a basis for more reliable predictions of future soil and water quality under the conditions of climate and land-use change. A special focus is laid on landscape elements such as rivers, subsections in the spring area of rivers, valley floors, fractured aquifiers and soil. The University of Stuttgart's contributions are in the areas of planning experiments and the assessment of uncertainties that are inevitable when modelling and simulating this kind of complex and not fully understood processes concerning pollutant transport.

Providing opportunities for young scientists: Research training groups

The focus of the Research Training Groups funded by the German Research Foundation is the qualification of doctoral researchers within the framework of a topically focused research program and a structured training concept. Research Training Groups with an interdisciplinary approach are most desired. The aim is to prepare doctoral researchers intensively for the complex “science” job market and at the same time foster their early scientific independence.

Technologies for droplet interactions (DROPIT)
Spokesperson: Prof. Bernhard Weigand, Institute for Aerospace Thermodynamics

Whether it concerns the spray cooling of food, the process of evaporation or combustion processes in engines: how droplets interact among each other and with surroundings plays a central role in many industrial uses. The technological progress in this field requires the development of adequate calculation approaches. Yet this is only possible if you analyze the hardly recognizable detail processes at the phase boundary as well as the micro structure of surfaces. This is the goal of the German-Italian graduate college at the University of Stuttgart which receives funding from the German Research Foundation DFG already in the second period.

„Soft Tissue Robotics" - Simulation methods for the development of control and automatization strategies for robots when interacting with soft tissues

Spokesperson: Prof. Oliver Röhrle, Professor for „Continuum Bio Mechanics and Mechano Biology“ in the Exzellence Cluster Simulation Technology and Institute for Modelling and Simulation of Biomechanical Systems

Whether you look at exoskeletons, fully automatic apple pickers or picking up parts in butchery: numerous challenging problems occur when ‘stiff’ robots have to deal with soft tissues. Finding solutions is the task of the new international graduate college (IKG) “Soft Tissue Robotics - Simulation methods for the development of control and automatization strategies for robots when interacting with soft tissues” at the University of Stuttgart. The IKG has the University of Auckland, New Zealand as a partner.

To improve basic knowledge the research concentrates its main focus on simulation technologies, automatization and control as well as the combination of technological and biological concepts. First of all, simulation techniques and sensors are to be further developed to enable an estimation of the deformation of materials after certain interactions. The second goal is the development of regulation and control technologies for robots interacting with soft tissues.

Intraoperative Multisensory Tissue Differentiation in Oncology
Spokesperson: Prof. Dr. Oliver Sawodny, Institute for System Dynamics

The GRK of the University of Stuttgart and the University of Tübingen will perform research in the field of medical technology to develop innovative sensor systems. These will enable cancer surgeons to differentiate at high resolution between malignant and healthy tissue during surgery, enabling them to better determine if tissue needs to be removed or preserved. In the long term, the aim of the GRK is to employ real-time data to improve patient safety and to shorten lengthy operations. Researchers from the University of Stuttgart will focus on sensor development and improvement, tissue modeling and classification of the data collected.

High-quality teams: DFG research units

A DFG research unit is a close-knit team of several outstanding scientists from a university who cooperate with researchers at other institutes on medium-term – generally up to six years – research projects that, in terms of thematic focus, duration and funding extend considerably beyond regular individual grant programs. Research units frequently contribute to establishing new research directions.

"Unsteady flow and interaction phenomena at high speed stall conditions" (Research Group 2895)

Aircraft should become more energy efficient and at the same time fly stable and quietly. To achieve this, it is necessary to gain a better understanding and prognosis of the flow-physics up to the borders of the flight envelope. This is precisely the aim of a new group of the German Research Foundation (DFG) entitled "Unsteady flow and interaction phenomena at high speed stall conditions". The speaker is Dr Thorsten Lutz from the Institute of Aerodynamics and Gas Dynamics at the University of Stuttgart. The Technical Universities of Munich and Braunschweig, the RWTH Aachen University and the German Aerospace Center (DLR) are also involved in the research group.
