Abstract:

A review is made of the effect of axial flow on cylindrical structures. Axial flow is related to fluidelastic instabilities at sufficiently high flow velocities. For the range of flow velocities and other parameters pertaining to most industrial systems, the effect of purely axial, uniform, steady flow is to damp free motions. Departures from such ideal flow conditions induce small amplitude vibration, termed sub-critical vibration. The underlying mechanism of this vibration is examined, and the various means available for predicting its amplitude are discussed. Modified author abstract
