A review on flow-induced vibration of offshore circular cylinders

Abstract

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 decades. Apart from its scientific significance in rich physics, VIVs are paid great attentions by offshore engineers, as they are encountered in many ocean engineering applications. Recently, with the development of research and application, wake-induced vibration (WIV) for multiple cylinders and galloping for VIV suppression attachments are attracting a growing research interest. All these phenomena are connected with the flow-induced vibration (FIV). In this paper, we review and give some discussions on the FIV of offshore circular cylinders, including the research progress on the basic VIV mechanism of an isolated rigid or flexible cylinder, interference of multiple cylinders concerning WIV of multiple cylinders, practical VIV suppression and unwanted galloping for cylinder of attachments. Finally, we draw concluding remarks, give some comments and propose future research prospects, especially on the major challenges as well as potentials in the offline/online modelling and prediction of real-scale offshore structures with high-fidelity CFD methods, new experimental facilities and applications of artificial intelligence tools.

Spring-Arrangement Effect on Flow-Induced Vibration of a Circular Cylinder

“…In the present experimental setup, the radius of the cylinder's rotation was kept constant (Table 1). Previous studies on FIV have reported the significance of two-dimensionality of the motion comprising the cross-flow and in-line components (e.g., [19,20]). The rotational motion generally involves both components; therefore, a radius of the cylinder's rotation that gives rise to a two-dimensional FIV to the maximum extent, may enable an increase in the available energy.…”

A review of experiments on stationary bluff body wakes

“…This research area has received much attention in recent decades. [6][7][8][9][10][11] Furthermore, studies dedicated to the flow around 3D geometries arising from spanwise inhomogeneity, truncated cylinders and presence of wall have formed another realm of research.…”

Fluid forces and vortex patterns of an oscillating cylinder pair in still water with both side-by-side and tandem configurations

“…Compared to the fluid-structure interaction (FSI) problem of cylinders open to the uniform flow [1] that has been widely investigated, cylinders relative to oscillatory flow has attracted less attention. However, its significance cannot be undermined for its rich physics as well as its existence in all kinds of engineering projects, especially in the ocean engineering field.…”
