DOI: 10.1016/j.jfluidstructs.2018.08.002
Abstract: Abstract Phenomenological wake–cylinder oscillators have been extensively implemented for vortex-induced vibration (VIV) predictions. Although such models capture fundamental VIV phenomena, the maximum response estimations and comparisons with different experimental data reveal some quantitative discrepancies due… read more here.
