抄録

Tube arrays in cross flows sometimes excite the acoustic vibrations of sound fields in ducts. It is very important, for practical applications, to understand the conditions of acoustic resonances in ducts with tube bundles. Exciting forces due to tube arrays of pitch-to-diameter ratio of 1.57 were measured in a water model duct and the characteristics of acoustic resonance in ducts with tube arrays were revealed. The results of the experiments agree with the field test data very well.
