Outline of Final Research Achievements

We have proposed the new prediction method of acoustic resonance in tube banks of exhaust heat recovery boiler. The phase characteristics of vortex shedding were experimentally investigated in in-line tube banks. As a result, the following conclusions were obtained. The phase delay between pressure drop at measured tube and acoustic pressure on the side wall as a function of gap velocity during the occurrence of acoustic resonance. The phase decreased from about－0.5π to －π as the gap velocity increased. This value agreed well with the result of theoretical one. The acceleration feedback for the coupling condition between sound field and wake oscillator were effective. The effects of a tube vibration on Karman vortex shedding were similar to those of acoustic resonance on vortex shedding without tube vibration.
