Suppressing acoustic pulsations is a critical task in modern premixed combustion-involved gas turbines. As a classical acoustic noise damper, Helmholtz resonator is generally applied in gas turbine combustors to reduce the transmission of acoustic perturbations. However, the neck configuration of a Helmholtz resonator may be designed in different ways. To obtain an optimum design and to compare the noise damping performances of these different configurations of the resonator necks, comparison study is conducted via developing a 2D linearized Na...
