Galloping motion has long been differentiated from other flow-induced motions like VIV and flutter based on the asymmetry of the flow present causing instability. Galloping instabilities can occur for circular cylinders due to proximity to a boundary or asymmetric cross-sections from strakes or other flow interference. The response of a bluff body due to galloping instabilities is still an active...
For many decades now, the idea of Vortex-Induced Vibrations (VIV) being modeled as a lock-in phenomenon of a mass-spring-dashpot system with an ideal added mass term has prevailed. In 2000, it was suggested by Vikestad et al. [1] that VIV may be modeled as a resonance phenomenon with variable natural frequency due to a variable added-mass term. In this paper, the variable added-mass approach is used...
