Acoustic resonance by length of acoustic baffle at Finned Tube bank
핀-튜브군에서 배플 길이에 따른 음향공진
Abstract
This paper presents phenomena of vibration and noise due to acoustic resonance in tube bank of a HRSG. Acoustic resonance is may arise when the vortex shedding frequency coincides with the acoustic natural frequency. At this tube bank, dominant frequencies of vibration in this system were 43.5, 67.5㎐.
