Simulation of combustion processes

In the field of combustion we collaborate with internationally leading groups from the University of Utah, Chalmers University (Göteborg), CIEMAT (Madrid) and Sandia (Livermore). In detail the following topics are investigated.

Thermoacoustic instabilities

[Translate to Englisch:] Moderne stationäre Gas​tur​binen sind anfällig für thermoakustische Instabilitäten, welche starke Materialbelastungen verursachen können. Die Schwingungen entstehen durch eine subtile Interaktion von Schwankungen der Wärmefreisetzung und Druckwellen in der Turbine.
