Modelling of coupled cross-flow/in-line vortex-induced vibrations using double Duffing and van der Pol oscillators (2012, methodology): “By way of examples, experimental input data (Blevins and Coughran, 2009; Dahl et al., 2006; Jauvtis and Williamson, 2004; Stappenbelt et al., 2007) whose Reynolds numbers are within the sub-critical flow regime are considered.”
A review of recent studies on vortex-induced vibrations of long slender cylinders (2012, background): “It was slightly different from the phase angle given later by Dahl et al. (2007). They explained that the existence of the third harmonic may be attributed to the interaction of the motion trajectory of cylinder and vortices in its wake.”
Dual resonance in vortex-induced vibrations at subcritical and supercritical Reynolds numbers (2010, methodology): “Studies by Sarpkaya (1995), Jauvtis & Williamson (2004) and Dahl et al. (2007) have shown that when the cylinder is also free to oscillate in-line with the flow, the hydrodynamic forces can be much different than those observed for a cylinder oscillating only in the crossflow direction.
