Optimisation of the Hydrodynamic Performance of a wave energy converter in an Integrated Cylindrical WEC-Type Breakwater System
Wave energy converters (WECs) are built to extract wave energy. However, this kind of device is still expensive for commercial utilisation. To cut down the cost of WECs by sharing the construction cost with breakwaters, an integrated cylindrical WEC-type breakwater system that includes a cylindrical WEC array in front of a very long breakwater is proposed to extract wave energy and attenuate incident waves. This paper aims to optimise the performance of the integrated cylindrical WEC-type breakwater system. A computational fluid dynamics tool, OpenFOAM®, and a potential flow theory-based solver, HAMS®, are utilised. OpenFOAM® provides viscosity corrections to a modified version of HAMS® in order to accurately and efficiently predict the integrated system's performance. Parametric studies are conducted to optimise the integrated system, and a novel setup with an extra arc structure is found to significantly improve the performance of the integrated system.
期刊介绍：
The Journal of Offshore Mechanics and Arctic Engineering is an international resource for original peer-reviewed research that advances the state of knowledge on all aspects of analysis, design, and technology development in ocean, offshore, arctic, and related fields. Its main goals are to provide a forum for timely and in-depth exchanges of scientific and technical information among researchers and engineers. It emphasizes fundamental research and development studies as well as review articles that offer either retrospective perspectives on well-established topics or exposures to innovative or novel developments. Case histories are not encouraged. The journal also documents significant developments in related fields and major accomplishments of renowned scientists by programming themed issues to record such events.
