Description

The excitation of high amplitude vibrations in heat exchanger models has been investigated with the aim of finding rules which can be used to ensure that fluid-elastic vibrations can be avoided in power plants. It has been found that unstable pressure distribution around the tubes is the reason for the excitation of the vibrations. By changing the damping and natural frequency of the tubes, the influence of the tube material was detected. Theoretical considerations and experimental results yield a rule which enables engineers to find a criterion for the safe layout of full-size heat exchangers. (author)
