Summary:This paper presents the theoretical method to evaluate the amplitude of flow-induced acoustic resonance of tube banks in the heat exchanger. This method, based on the forced oscillation model, employs the acoustic characteristics of the chamber containing tube banks and vortex-induced exciting forces with particular Strouhal number which changes with pitch to diameter ratio of tube array. Experimental results on acoustic resonance in transverse and flow direction agree well with the calculated results. Furthermore, the availability of the sound absorbing materials and the baffle plate with clearanceto reduce the acoustic resonance are discussed.
