“…While tube failure is often attributed to corrosion at the support locations, tube fretting wear due to flow-induced vibration has been recognized as a significant contributor. These destructive flow-induced vibrations are due to a number of different mechanisms, usually classified as fluid-elastic instability, vortex shedding and turbulence buffeting (Blevins 1979;Pettigrew 1981;Pa. ı ıdoussis 1982;Weaver & Fitzpatrick 1988).…”

“…In addition, during the several past decades, many researchers involved in FIV have conducted experimental and analytical studies, especially on cross flow conditions such as in steam generators. 1,4,5) Such extensive works reveal many aspects of vibration in the cross flow, but research activities related to axial flow induced vibration are rather rare since the problem is more severe in cross flow condition than in or axial flow condition. Although relatively small, the vibration in the axial flow may cause an impact, which may result in wear and fretting damage of the fuel rod 6) and change in local flow parameters, such as the void fraction profile, Sauter mean diameter, turbulence intensity at the near of surface, etc.…”

The CHF generally increases with vibration intensity, which is represented by vibrational Reynolds number (Re v ); the CHF enhancement is more dependent on amplitude than on frequency. CHF enhancement seems to come from the reinforced flow turbulent mixing effect by vibration in the vicinity of heat transfer surface. Based on the experimental results, an empirical correlation is proposed for the prediction of CHF enhancement by tube vibration. The correlation predicts the CHF enhancement ratio (En) with reasonable accuracy, with an average error rate of −2.18% and 27.75% for RMS.

“…Mechanical failures have occurred after several years of service, due to small-amplitude oscillations caused by turbulence, or after short periods of time due to large-amplitude, self-excited oscillations. Both excitation mechanisms have been the subject of extensive experimental and analytical research, leading to predictive models and design guidelines [see, for example, Pettigrew (1981), Paı¨doussis (1983), Chen (1984), Singh & Soler (1984) and Weaver & Fitzpatrick (1987)]. Researchers have also attempted to identify the interaction effect between turbulence and fluidelastic instability.…”
