ESDU 88028 complements ESDU 87019@ which provides prediction methods for vibration of heat exchanger bundles. After outlining the nature of acoustic resonance@ calculation methods are given for the acoustic frequency in both rectangular and cylindrical ducts. Procedures@ based on a correlation of all the available acoustic data (all data on periodic wake shedding derived from measurements in the flow field were discarded because of their inapplicability)@ are given for the prediction of resonance. Possible damage caused by acoustic resonance is considered@ and the means by which a design can be modified@ before or after fabrication@ are discussed. The methods apply to bundles in a rectangular cross-section duct@ to shell-and-tube heat exchangers and to helical coil arrangements.
