  • 1506 The method of reduction for the resonance of a circular pipe generated by an impinging jet

抄録

Self-sustained oscillation of a shear layer occurs in the jet-pipe system when a pipe is placed coaxially with around jet axis. The velocity fluctuation in this phenomenon is accompanied by a pure tone radiating from the leading edge of the pipe. Though the level of this tone is generally very small, a high sound level is produced by produced by the coupling of the acoustic resonance of the pipe to the periodic oscillation of the flow in the jet. In this paper several methods are proposed in order to attenuate the acoustic resonance produced by this coupling, and the effect of attenuation is investigated experimentally.
