The Zero Mass Flow Liner is able to convert a perforated liner with minimal damping qualities into a very effective sound absorber. The damping improvement results from an additional acoustic excitation within the Zero Mass Flow Liner. This paper stu

Perforated liners with bias flow are integrated in the wall of gas turbine combustors to suppress thermoacoustic instabilities. The suppression of these unstable pressure oscillations is a requirement for the safe and stable operation of a gas turbin

An optimization method for the calculation of the wall impedance of a perforate from measurements under grazing flow conditions is presented. It is in particular characterized by the simultaneous eduction of the parameter set defining the impedance a

Perforated liners, especially in combination with a bias flow, are very effective sound absorbers. Applied to gas turbine combustors they can suppress thermoacoustic instabilities and thus allow the application of new combustion concepts concerning h
