内容記述 | Self-sustained oscillation of a shear layer occurs in the jet-pipe system when a pipe is placed coaxially with a round jet axis. The velocity fluctuation in this phenomenon comes to have a periodical regularity, and then 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 the coupling of the acoustic resonance of the pipe to the peridic oscillation of the flow in the jet. In this paper several methods are proposed in order to attenuate the acoustic resonace produced by this coupling, and the effect of attenuation for various methods is investigated experimentally. | |||||
