Our Projects & Cooperations

Research at STFS is funded and supported by multiple national and international projects, which currently involves two Collaborative Research Centres of the German Research Foundation.

Collaborative research

Iron as a reactive metal has enormous potential to boost the energy transition. The project Clean Circles teams up scientists from multiple disciplines to explore how the metal and its oxides can be used in a cycle as carbon-free chemical energy carrier to store wind and solar power Learn More

Development of Models and Methods to describe Solid Fuel Combustion in an Oxy Fuel Atmosphere

The safe supply of energy and electrical power will require operation of conventional power plants in the next decades until technical development enables the supply mainly by regenerative sources at minimum emissions of climate gases. Learn more

The Rolls-Royce University Technology Centre at TU Darmstadt was founded to investigate the aerodynamic and thermal interaction between combustion chamber and turbine. In a strategic partnership between science and industry, we develop new technologies for aircraft engines that will meet future economic and ecological goals.


  • HydrogEn combuSTion In Aero engines (HESTIA)
  • Hydrogen combustion technology for new generation drive systems (WotAn)
    • Investigation of turbulent mixing and flame structure in a hydrogen combustion chamber
  • Particle and emission reduction technology for efficient and environmentally friendly drive systems (PERseuS)
    • Development of methods for the detailed prediction of soot and NOx formation in the combustion chamber as well as virtual, cross component, modelling of interaction mechanisms between combustor and turbine.
  • Consortium for the AdVent of aero-Engine Demonstration and aircraft Integration Strategy with Hydrogen (CAVENDISH)
  • Cost- and performance-optimized combustion chamber turbine technologies for modern turbo generators electric aircraft engines (OptTuGen)
    • Modeling of thermoacoustic instabilities in H2 combustors using hybrid CFD/CAA.
  • Testability and testing of H2 drive systems and components (TeTeAnt-H2)
    • Flexible Fuel Nozzle – Modeling and Simulation of Turbulent Dual Fuel Combustion (H2 and Sustainable Aviation Fuels)

In this Priority Program SPP 2419 HyCAM, a new interdisciplinary approach is being pursued that combines the competencies of combustion research and additive manufacturing. The hypothesis of the SPP is that only a comprehensive understanding of combustion fundamentals as well as the integration of modern 3D manufacturing processes through simulation-based design can enable the simultaneous improvement of flexibility, efficiency and emissions in thermochemical energy conversion processes.

Internal combustion engines, in particular gasoline engines, operate with cyclic variations. Cyclic variability has been observed since the earliest scientific studies on internal combustion engines in terms of the changes in easily measurable operating parameters, such as the maximum cylinder pressure, from one cycle to another. In extreme cases, these variations can lead to misfires or knocking combustions, and in supercharged engines under certain conditions also to so-called mega-knock. Cyclic variations and the resulting unstable combustion are the major limitations for further efficiency improvements in highly optimized gasoline engines. Better understanding and modeling of the underlying physical-chemical processes offer the potential to achieve significant improvements in terms of stability, efficiency and emissions. Learn more

In NHR4CES (National High Performance Computing Center for Computational Engineering Science), TU Darmstadt and RWTH Aachen University join forces to combine their strengths in HPC applications, algorithms and methods, and the efficient use of HPC hardware. The goal is to create an ecosystem combining best practices of HPC and research data management to address questions that are of central importance for technical developments in economy and society.

INNO4SCALE is a European initiative, which was started to support the development of innovative algorithms for exascale supercomputers, so their efficient use can be fully exploited. Currently existing codes for high-performance computing will not be able to function efficiently on upcoming exascale systems in the future. Therefore, the project will identify and support the development of applications that have the potential to fully exploit the new upcoming EuroHPC exascale systems. The most successful application will be taken up by science and industry after the project.

National Research Data Infrastructure for Engineering Sciences

NFDI4Ing unites engineering research communities and promotes the management of their research data. The consortium represents researchers from every engineering field. It offers a unique method-orientated and user-centred approach to making research data FAIR – findable, accessible, interoperable and reusable.

The Task Area “Alex” (bespoke experiments) focuses on the challenges that engineers face when developing and performing a one-of-a-kind experiment to study a technical system. The experiment can be real or virtual and encompasses bespoke software and hardware solutions.
