Abstract: Tube banks located in flow channels and exposed to crossflow have a low resistance to acoustic resonance and vibration in general. Such resistance can be increased substantially by placing ...

Abstract: Flow channels of heat exchangers or steam generators containing tube arrays can be subject to acoustic vibration excited by flow of air, gas, or steam tranversely across the tubes. Such vibration ...

Abstract: Criteria are formulated for the development of acoustic vibration in transverse acoustic modes in steam generator tube banks, based on flow and acoustic parameters. Theoretical predictions are ...

Abstract: Tube banks of operating steam generators were evaluated for resonant acoustic vibration in the transverse acoustic mode, using a number of published vibration criteria and a range of Strouhal ...

Abstract: Acoustic vibration in two stack liners located inside a stack downstream of two induced draft fans occurred at high loads. Measurements confirmed that an acoustic wave developed in the fundamental ...
