Intermittency: A State that Precedes Thermoacoustic Instability
2017Thermoacoustic instability is a plaguing problem in confined combustion systems, where self-sustained periodic oscillations of ruinous amplitudes that cause serious damage and performance loss to propulsive and power generating systems occur. In this chapter, we review the recent developments in understanding the transition route to thermoacoustic ...

Modeling, Analysis, and Control of Thermoacoustic Instabilities
2010Moderne Gasturbinen werden mit magerer Vormischverbrennung betrieben, um niedrige Emissionsstandards zu erfüllen. Diese Art der Verbrennung ist jedoch äußerst anfällig gegenüber Störungen der Flamme durch akustische Schwankungen. Hierdurch entstehen sogenannte thermoakustische Instabilitäten, die sich durch außerordentlich hohe Druckpulsationen ...

Low order modeling of thermoacoustic instabilities
2022Pollution and The Greenhouse Effect are a concern in our society. The high levels of CO2, NOx, ozone, and methane gasses are alarming and have pushed gas turbine industries to develop more environmentally friendly combustors. In the past years, Lean Premixed Combustors have been identified as a potential solution.
