## Modelling of coupled cross-flow and in-line vortex-induced vibrations of flexible cylindrical structures. Part I

### Model description and validation

This paper is first of the two papers dealing with the nonlinear modelling and investigation of coupled cross-flow and in-line vortex-induced vibrations (VIVs) of flexible cylindrical structures. As a continuation of the previous work (Qu and Metrikine in Ocean Eng 196:106732, ...

An experimental investigation on the coupled dynamics of an offshore tunnel-rig system from the element launching to its near-seabed immersion in irregular waves is conducted, where the motions of tunnel/rigs and the tensile forces of the suspension lines are evaluated in a sy ...

The authors regret that there are a few typological errors in Eqs. (9) and (13) and (15)–(17). For Eqs. (9), (13) and (17), the signs of the first terms are wrong and they should be corrected as follows: [Formula presented] [Formula presented] [Formula presented] A symbol L is ...

## Modelling of coupled cross-flow and in-line vortex-induced vibrations of flexible cylindrical structures

### Part II: on the importance of in-line coupling

To illustrate the influence of the in-line coupling on the prediction of vortex-induced vibration (VIV), the simulation results of the coupled cross-flow and in-line VIVs of flexible cylinders- obtained with three different wake oscillator models with and without the in-line c ...

In this paper, a new wake oscillator model with nonlinear coupling is proposed for the modelling of vortex-induced vibration. The purpose is to develop a model that is capable of reproducing both free and forced vibration experiments. To achieve this goal, an existing van der ...
