Bernhard Cosic, Auteur ; Thoralf G. Reichel, Auteur ; Christian Oliver Paschereit, Auteur |Helmholtz resonators are often used in the gas turbine industry for the damping of thermoacoustic instabilities. To prevent thermal destruction, these devices are usually cooled by a purging flow. Since the acoustic velocity inside the neck of t[...]

Sebastian Schimek, Auteur ; Jonas P. Moeck, Auteur ; Christian Oliver Paschereit, Auteur |Due to stringent emission restrictions, modern gas turbines mostly rely on lean premixed combustion. Since this combustion mode is susceptible to thermoacoustic instabilities, there is a need for modeling tools with predictive capabilities. Line[...]

Holger J. Konle, Auteur ; Christian Oliver Paschereit, Auteur ; Ingo Röhle, Auteur |A high temperature resistant fiber-optical microphone (FOM) was developed and successfully applied in a combustion chamber at a thermal power of 8.4 kW to measure thermo-acoustic oscillations at a frequency of 85 Hz and a sound pressure level of[...]

Mirko R. Bothien, Auteur ; Jonas P. Moeck, Auteur ; Christian Oliver Paschereit, Auteur |Linear stability analysis by means of low-order network models is widely spread in industry and academia to predict the thermoacoustic characteristics of combustion systems. Even though a vast amount of publications on this topic exist, much les[...]

Steffen Terhaar, Auteur ; Bernhard C. Bobusch, Auteur ; Christian Oliver Paschereit, Auteur |During the design and testing process of swirl-stabilized combustors, it is often impractical to maintain identical outlet boundary conditions. Furthermore, it is a common practice to intentionally change the acoustic boundary conditions of the [...]

Arnaud Lacarelle, Auteur ; Christian Oliver Paschereit, Auteur |Jets in crossflow are widely used in the industry for homogenization or cooling tasks. Recently, pulsating jets have been investigated as a mean to increase the scalar mixing efficiency of such configurations, whether for a single jet or for an [...]

Mirko R. Bothien, Auteur ; Christian Oliver Paschereit, Auteur |In the design process, new burners are generally tested in combustion test rigs. With these experiments, as well as with computational fluid dynamics, finite element calculations, and low-order network models, the burner's performance in the ful[...]
