Prediction of vortex-induced vibration response by employing controlled motion (2009, methodology): “For both Reynolds numbers, the controlled-vibration contours yield good agreement with the empirical formula, taking into account mass damping as well as the Reynolds number, deduced by Govardhan & Williamson (2006), A∗ = (1 − 1.2α + 0.30α2) log (0.41Re0.”
Dual resonance in vortex-induced vibrations at subcritical and supercritical Reynolds numbers (2010, methodology): “In the case of a freely vibrating cylinder in the subcritical-Reynolds-number regime, Govardhan & Williamson (2006) found that as the Reynolds number increased over their analysed range, the oscillation amplitude and lift forces acting on the cylinder were also found to increase.”
Experimental investigation of Reynolds number effect on vortex induced vibration of rigid circular cylinder on elastic supports (2011, methodology): “Recently, research groups at Caltech and Cornell have been trying to corroborate that the VIV amplitude of oscillation is a function of Reynolds number around Re¼4.5 103 (Govardhan and Williamson, 2006).”
Modelling of coupled cross-flow/in-line vortex-induced vibrations using double Duffing and van der Pol oscillators (2012, background): “…had a discussion on whether the combined massdamping, viz. the Skop–Griffin parameter SG=2ヾ3St2m*ξ (Williamson and Govardhan, 2004), could reasonably collapse different peak (typically cross-flow) amplitude data of different cylinders in the Griffin plots (Govardhan and Williamson, 2006).”
Mechanism of frequency lock-in in vortex-induced vibrations at low Reynolds numbers (2015, background): “The effects of the mass ratio (Prasanth, Premchandran & Mittal 2011), the structural damping coefficient (Nguyen et al. 2012) and the Reynolds number (Govardhan & Williamson 2006) on the lock-in regime have also been extensively studied.”
