抄録

Acoustic resonant vibration occurs in cavity with tube bundle when flow velocity reaches at a certain velocity. Mode of the vibration is usually transverse to flow direction and way of prevention is not very difficult. However, in recent years, vibration of parallel mode sometimes occurs. Cause of the vibration must be an increasing of flow velocity and complication of duct shape. There is no effective method to prevent the vibration so that it is very important to find out a method of judgment in design stage, whether the acoustic resonant vibration will occus or not. Vortex shedding is influenced by the acoustic vibration and the vibration is also influenced by the vortex shedding, so the acoustic vibration seems to have feed back loop. Mechanism of the vibration having a feed back circuit is discussed in thip paper.
