Flow-induced vibration of steam generator tubes. Final report
Technical Report
·
OSTI ID:5693812
This report presents results concerning flow-induced vibration in a square pitch tube bundle successively subjected to air-water flow of density ranging from 40 to 400 kg m/sup -3/. The most prominent vibration excitation mechanism observed was fluidelastic instability. Air-water and steam-water critical flow velocities are adequately predicted using the classical Connors' proportionality factor of 7. Turbulent excitation of the tube bundle was also investigated. 156 figs., 39 tabs.
