“…However, recently a number of studies have begun to incorporate EMCSs into CNWT experiments to allow a more realistic evaluation of the EMCS performance. In [170,189,190] modify the CNWT setup outlined in [126], to implement and evaluate different control strategies. Giorgi and Ringwood [170] describe the implementation of latching control in a CNWT, which is used to evaluate optimal latching duration for a heaving PA in regular waves.…”

“…Giorgi and Ringwood [170] describe the implementation of latching control in a CNWT, which is used to evaluate optimal latching duration for a heaving PA in regular waves. Davidson et al [189] implement proportional-integral (PI) control, where the PI parameters are selected using SI techniques from [126,164]. Comparing the CNWT results against PF simulations shows that the PF simulations overestimate the WEC motion and power absorption.…”

For the research and development (R&D) of wave energy converters (WECs), numerical wave tanks (NWTs) provide an excellent numerical tool, enabling a cost-effective testbed for WEC experimentation, analysis and optimisation. Different methods for simulating the fluid dynamics and fluid structure interaction (FSI) within the NWT have been developed over the years, with increasing levels of fidelity, and associated computational expense. In the past, the high computational requirements largely precluded Computational Fluid Dynamics (CFD) from being applied to WEC analysis. However, the continual improvement and availability of high performance computing has led to the steady increase of CFD-based NWTs (CNWT) for WEC experiments. No attempt has yet been undertaken to comprehensively review CNWT approaches for WECs. This paper fills this gap and presents a thorough review of high-fidelity numerical modelling of WECs using CNWTs. In addition to collating the published literature, this review tries to make a step towards a best practice guideline for the applications of CFD in the field of wave energy.

To maximise the energy output of wave energy converters (WECs), large structural motions are desired. When simulating WEC performance in Computational Fluid Dynamics (CFD) based numerical wave tanks, these motions must be explicitly accommodated in the computational domain. Using well established mesh morphing (MM) methods, this explicit accommodation results in deformation of control volumes (CVs)/mesh. Thus, large amplitude WEC oscillations may lead to highly distorted CVs and push MM models beyond the limits of numerical stability. While advanced numerical mesh motion methods, such as overset grids, have been developed in commercial CFD codes to overcome these issues, little use of these methods can be found in WEC analysis. However, recently the overset grid method (OSG) has been made available to a wider user community through its release in the open source CFD environment OpenFOAM [1,2]. To evaluate the performance of the OSG, this paper will compare the classical MM method and the OSG against experimental tank test data of the WaveStar device [3].

“…Full details of the CNWT implementation can be found in [52]. The setup of the CNWT has first been verified comparing the performance of a WEC simulated in the CNWT against results of a BEM model [36,39,53], and then validated against physical experiments of a 1:10 scale WEC in [54].…”
