Wave Power Extraction From A U-Shaped Oscillating Water Column Consisting Of A Flexible Bottom-Standing Front Wall, Siming Zheng, Haojie Zheng, Simone Michele, Guixun Zhu, Yeaw Chu Lee, Deborah Greaves

School of Engineering, Computing and Mathematics

In this paper, the concept of a U-shaped oscillating water column (UOWC) device consisting of a flexible bottom-standing front wall is proposed. The deflection of the flexible wall could bring benefits for wave power absorption. To evaluate the hydrodynamic performance and predict the wave power absorption of the flexible UOWC, a theoretical model based on the linear potential flow theory and the Galerkin approximation method is developed. For some examined flexible UOWCs, three peaks of the frequency response of the maximum wave power capture efficiency are observed, in which two are related to the resonant frequencies of the oscillating water …

A New Cfd-Mbd Wave-Structure Interaction Model: Coupling Openfoam With Chrono, Haifei Chen, Tianyuan Wang, Deborah Greaves, Hongda Shi, Qingping Zou

School of Engineering, Computing and Mathematics

Interconnected multibody floating structures have gained popularity recently. The dynamic response of moored interconnected floating bodies to wave action, however, are complicated and challenging to model and analyze. To tackle the problem, a novel wave-structure-interaction (WSI) model is developed for the first time by coupling a finite volume CFD model, OpenFOAM, with Project Chrono, a multi-physics simulation engine for multibody dynamics (MBD) and finite element analysis, through linking pre-compiled dynamic libraries. This paper focuses on dynamic behavior of rigid structures restrained with a mooring system. To account for the floating body motion in the fluid solver, both mesh deformation and …

Scaled Physical Modelling Of Floating Offshore Wind Turbines Using A Neural Network-Based Surrogate Model For Aerodynamic Emulation, Emma C Edwards, Edward Barbour, Tom Tosdevin, Edward Ransley, Kieran Monk, Alastair Reynolds, Anna Holcombe, Scott Brown, Deborah Greaves, Martyn Hann

School of Engineering, Computing and Mathematics

Scaled physical modelling of floating offshore wind turbines is a crucial step in the continued development of floating offshore wind to reach Net-Zero goals. However, it is an inherently difficult task due to the incongruity between Reynolds scaling (important for wind effects) and Froude scaling (important for wave effects). One option to overcome this difficulty is to use a real-time hybrid testing approach, whereby a Froude-scaled model is tested in a wave basin with a thruster replacing the wind turbine. Typically, a low-fidelity numerical model is run in real time to determine the appropriate aerodynamic thrust applied by the thruster. …
