Simulation of Reactive Thermo-Fluid Systems
At the Institute for the Simulation of Reactive Thermo-Fluid Systems (STFS), we develop models and conduct simulations of sustainable energy systems.
Our mission
To power a sustainable world, our research focuses on chemical energy carriers and exploits the potential of renewable fuels such as hydrogen, ammonia, methanol, iron and aluminum. We develop advanced modeling approaches and simulation techniques for chemically reactive laminar and turbulent multicomponent and multiphase flows. We use these simulation techniques to investigate combustion processes on all scales: from the smallest structures of the reaction zone and the formation of nanoparticles in solid fuel flames to the largest scales of of technically relevant combustion chambers.
The work of our research group is characterized by a close connection between fundamental and application-oriented research. Our aim is to understand the physical principles of combustion through direct numerical simulations (DNS) and to combine this knowledge in advanced mathematical models. By coupling these models with scale-resolving large-eddy simulations (LES), we can investigate even very complex practical applications such as aircraft engines, industrial furnaces and chemical reactors.
To achieve our goals, we work closely with colleagues, especially experimentalists, from science and industry.
Prof. Dr.-Ing. Christian Hasse,
Head of STFS
In our research, we investigate clean energy conversion processes. With simulations on high-performance computers, we gain detailed insights into reactive flows that were unthinkable just a few years ago. In doing so, we bridge the gap between basic research and technical applications.

New colleagues at STFS
Over the coming months, several PhD candidates (Philipp Koob, Bich-Diep Nguyen, Driss Kaddar, Tim Jeremy Patrick Karpowski, Jannis Reusch) will complete their theses, while new researchers have joined Simulation of Reactive Thermo-Fluid Systems (STFS), TU Darmstadt. What makes me especially happy is that each of them joined through long-standing, trusted collaborations — each following a unique path.
