In this work, the effects of the grazing flow and its geometric dimensions on the aeroacoustics damping performance of a Helmholtz resonator are numerically evaluated. The grazing flow tangentially passing through the neck of the resonator is characterized by Mach number. And it is varied from 0 to...
