... depth, the bias flow, and the plate perforation. At the oscillation frequency, the reflection coefficient’s magnitude could be reduced to 0.15–0.2, causing a pressure peak reduction of 10 dB in the combustion chamber. The concept of changing the acoustic boundary condition to render a system stable...

... engine is sought to be predicted. Especially, information about the thermoacoustic behavior and the emissions is very important. As the thermoacoustics strongly depend on the acoustic boundary conditions of the system, it is obvious that test rig conditions should match or be close to those of the full...
