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.

“…The influence of slope on the dike has been predictable through a lot of studies, like the research done by Evangelista 16 . Liu et al 17 studied the slope ratio by the numerical simulation method. They conclude that the overtopping discharge will be optimized when the slope ratio ranges from 1:1.5 to 1:2.…”

The geometrical model was built by the computer-aided design software and imported into STAR-CCMþ. Typical wave conditions in the East China Sea were used in computational fluid dynamics simulation. By observing overtopping process and recording water discharge, the relationship between wave conditions and overtopping process was obtained. Finally, the simulation was validated by comparing the theoretical and experimental results. Furthermore, an empirical model was developed to predict the water discharge.

This work presents a 2D numerical study of an Oscillating Water Column (OWC) converter considering physical constraints in its outlet chimney to represent the turbine pressure drop. Two strategies were adopted. The first considers different dimensions for a physical constraint similar to an orifice plate, being the analysis performed in a laboratory scale. After that, other physical restriction with geometry similar to a rotor turbine was investigated in a real scale by means a dimensional variation. The numerical results indicate the importance of consider the pressure drop caused by turbine in the analysis of the OWC behavior.
