Hydrodynamic Damping, Flow-Induced Oscillations, and Biharmonic Response

Abstract

A brief review of damping is followed by a comparison of three sets of lift-force data for circular cylinders, subjected only to transverse oscillation. Then the significance of two-dimensional or biharmonic oscillations (in both the in-line and transverse directions) is discussed in light of experiments undertaken for that purpose, to simulate more closely the true nature of flow-induced oscillations.
