... of the acoustic resonances at a range of operating conditions. The main resonant frequencies are to be found around 605 Hz (associated with the plenum) and around 461 Hz and 823 Hz (associated with the combustion chamber), as well as one at around 22 Hz (a bulk mode associated with the system as a whole...

... measurement acoustic resonance Many large industrial gas turbines operating on pre-mixed natural gas suffer from high levels of dynamic pressure or “humming” in the combustion chambers that can sometimes prevent them from reaching full load and can lead to serious damage to internal components...
