Abstract: The development of a theoretical model for fluidelastic instability (FEI) in tube arrays is presented. Based on the simple model of Lever and Weaver, it considers a group of seven tubes which move in both the streamwise ...

Abstract: Flowinduced vibration is an important criterion for the design of heat exchangers in nuclear, fossil, and chemical plants. Of the several known vibration excitation mechanisms, fluidelastic instability (FEI) is the most ...

Abstract: This paper presents the results of an experimental model study of the transient loading of steam generator tubes during a postulated main steam line break (MSLB) accident in a nuclear power plant. The problem involves ...

Abstract: An experimental facility was designed and built to study the loading on steam generator tubes during a blowdown. The facility used refrigerant R134a and measurements were taken for static and dynamic pressures as well as ...
