| 内容記述 | A magic pipe is a flexible vinyl chloride pipe with bellows structure. The sound is generated by the air current running through the pipe, one of the generation reasons of which is taken as being related to cavity flow. So the characteristics have been examined of the sound generated from the magic pipe, which have been investigated from relation to cavity flow. In experiment the air has been issued from nozzle in atmosphere with blower, and the apparatus system has been made in which the sound is generated by setting up the magic pipe in the jet. It has been examined that the relation between the characteristics of the sound generated and the effects of the jet velocity, the pipe length or the pitch of bellows in the pipe. The results show that the generation reasons of the sound can be explained by the self-excited vibration phenomenon concerned with the cavity flow and the peak flequency of the sound spectrum is influenced by acoustic natural flequency of the pipe length. | |||||
