As a fundamental fluid-structure interaction (FSI) phenomenon, vortex-induced vibrations
(VIVs) of circular cylinders have been the center of the FSI research in the past several …

The mechanism of suppression for the vortex-induced vibration (VIV) of circular cylinder by
the helical wires is investigated using LES turbulence model. Numerical models for the free …

An experimental investigation was conducted on a flexible riser with and without various
strake arrangements. The aim of the present work was to further improve the understanding …

深海细长柔性立管的涡激振动与刚性圆柱的涡激振动问题相比, 既有联系又有区别.
当立管的长细比(L/D) 较大时, 会展现出一些刚性圆柱涡激振动没有的现象 …

The experiments on vortex-induced vibration (VIV) suppression for a circular cylinder with
helical strake by varying its heights, pitches, coverages and cross sections were carried out …

Experimental investigations were conducted on a flexible riser with and without helical
strakes. A uniform current was obtained by towing a riser model in a tank, and the vortex …

This study was done to investigate the effects of angle and spacing of Collar-rings
(innovative attachments for scour reduction over the circular piers) on the flow-induced …

Most flows of engineering relevance still remain unexplored in a global instability theory
context for two reasons. First, because of the difficulties associated with the analysis of …

Vortex-induced vibration (VIV) is very important to riser as VIV is closely related to fatigue
damage. Literature reviews demonstrate that very limited work has been done to address …

An experimental investigation was conducted on a flexible riser with and without various
helical strake coverages, with the aim of further improving the understanding of the response …
