The intense acoustic resonance resulting from gas flow across a bank of heat exchanger tubes in a duct has been investigated experimentally and theoretically. At low gas velocities, the acoustic tone emanating from tube bundles increases in proportion to the flow velocity. When the frequency approaches a bound acoustic transverse mode of the tube bundle, intense sound can result. Sound levels as high as 173 db were measured within the bundle. During resonance, the sound correlates vortex shedding from the tubes and the pressure drop increases in some bundles.

For the purpose of thermal and hydraulic and aerodynamic testing of the heat exchanger tube bundles, various full-scale tube specimens with different finning ratio have been proposed. Formulas that allow to evaluate the effect of the ratio of heat exchanging tube finning on the heat exchanger efficiency are presented.

This is neither an original paper nor a review, but a comparative overview of two seemingly unrelated engineering fields. There are some similarities and strong dissimilarities between multipipe risers and tube arrays employed in heat exchangers. For example, square arrays are used in both, whereas “satellite” clusters cannot be found in heat exchangers. The extensive research on flow-induced vibrations in heat exchanger arrays reveals several mechanisms of excitation and sustenance of tube vibration. Some of the mechanisms identified for tube arrays may be relevant for marine risers. The main object of this comparative overview is to compile and discuss heat exchanger data which may be applicable to marine risers. Design guidelines are specified for satellite clusters.
