Simulation of reactive Thermo-Fluid Systems
Welcome to the website of the Institute for Simulation of reactive Thermo-Fluid Systems. We focus on modeling and simulating (CFD = Computational Fluid Dynamics) thermo-fluid dynamic processes in mechanical and chemical process engineering. Typical technical applications include internal combustion engines, reactors in process engineering, gas turbines or catalysts.
The motivation for our research
The research group's work is characterized by close collaboration between basic and application-oriented research.
Fundamental research questions on relevant sub-processes often arise from technical applications. Some typical examples are turbulence-chemistry interaction, population balance dynamics, high-pressure sprays or fluid-wall interactions.
To this end, we develop mathematical models for applications involving the simulation of chemical engineering processes and the combustion of solid, liquid and gaseous fuels. This allows methods and results from fundamental research to be directly transferred to technical applications.
We are developing a suite of in-house software tools, but we also use packages such as OpenFOAM®, ANSYS® CFX® and ANSYS® Fluent®, extended by our methods and codes. Simulations are carried out on our own cluster and on large-scale computing facilities at national computing centers.
Prof. 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.

Oktober 04, 2021
Herr Dr.-Ing. Arne Scholtissek vom Fachgebiet Simulation reaktiver Thermo-Fluid Systeme (STFS) ist auf dem 30. Flammentag mit dem Warnatz-Preis geehrt worden. Der Flammentag ist eine Tagung, welche alle zwei Jahre im Auftrag der Deutschen Vereinigung für Verbrennungsforschung und der Deutschen Sektion des Combustion Instituts veranstaltet wird. An zwei Tagen wurden Themen rund um die Nutzung nachhaltiger Brennstoffe und die Energiewende adressiert.

Video: Retrofitting of exsiting power plants
June 15, 2021
One aspect of the transition to renewable energy production is now coming into focus: the climate-neutral retrofitting of existing infrastructures – power plants that will often be in operation for decades to come. The goal of Clean Circles is to make these plants CO2-free by retrofitting them with new technologies . Professor Christian Hasse is the project's spokesman and explains in the video how this can be achieved.
