摘要: This two-part review article presents an overview of mechanics pipes conveying fluid and related problems such as the fluid-elastic instability under conditions turbulence in nuclear power plants. In first part, different types modeling, dynamic analysis, stability regimes restrained by elastic or inelastic barriers are described. The behaviors pinned-pinned, clamped-clamped, cantilevered together with curved articulated will be discussed. Other made viscoelastic materials active control severe pipe vibrations considered. part closed conclusions highlighting resolved nonresolved controversies reported literature. second address problem single- two-phase flows fretting wear process equipment heat exchangers steam generators. Connors critical velocity discussed a measure initiating instability. Vibro-impact exchanger tubes random excitation cross-flow can produce progressive damage at supports through fatigue. Antivibration bar used to limit An assessment analytical, numerical, experimental techniques given. topics this include remote impact analysis parameter identification, damage-induced pressure waves, response long pipes, marine risers aspirating fluid, carbon nanotubes fluid.
