Abstract:
In this paper the authors focus to discuss the fluidelastic instability in tube arrays of heat exchangers.From the viewpoint of practical application,the tube-in-channel model ofLever and Weaver are utilized. However, the vibration of tube is considered as periodic damping(or divergent)motion and the fundamental equations are solved by means of complex method.According to the relation between reduced flow velocity and mass damping parameter, the stability map will be drawn out, which may be used to predict ...
