• Unusual noise is sometimes caused by tube type heat exchangers employed to recover waste heat from a gas turbine. There are a few studies on Karman vortex-induced noise from bare tubes or bare tube bank placed in the air flow, but no study concerning Karman vortex-induced noise from fin tube bank. For the purpose of this investigation leading to reduce Karman vortex-induced noise from heat exchangers, various fin tube models were made, and Karman vortex-induced noise was compared between this model and fin tubes used in a heat exchanger. As it was confirmed that there was an acceptable parallelism between the model and the fin tubes, the effect of interference plates on Karman vortex-induced noise was determined after variations of the position and eccentricity of interference plates placed at the trailing end of the fin tube banks. As a result, unusual noise due to Karman vortex-induced noise was successfully prevented.
