2. Flow-Induced Vibration of Nuclear and Process Equipment: An Overview

Failures due to excessive vibration must be avoided in process equipment, preferably at the design stage. Thus, a comprehensive flow-induced vibration analysis is required before fabrication of process equipment, such as shell-and-tube heat exchangers. It must be shown that tube vibration levels are below allowable levels and that unacceptable resonances and fluidelastic instabilities are avoided.
