Tube vibrations in heat exchangers are being systematically studied in a series of tests performed with an industrial-size test exchanger. Results from flow tests of nine different tube bundles, in a basic 5-baffle, 6-crosspass configuration on a 30/sup 0/-triangular layout with a pitch-to-diameter ratio of 1.25, are reported. the test cases include a full tube bundle, no-tubes-in-window bundle, finned tube bundle, and several proposed field fixes. The testing focused on identification of the lowest critical flowrate to initiate fluidelastic instability (large amplitude tube motion) and the location within the bundle of the tubes which first experience instability. The threshold flowrates are determined from a combination of methods based on sensory observations, vibration amplitude data, and frequency response information. Pressure drop data are also generated and reported.
