| Outline of Final Research Achievements |
This research aims to study the wave interaction phenomenon amongst arrays of wave energy converters (WECs) and the possibility of achieving synthetical optimization. For this purpose, by coupling a refined boundary element method and the interaction theory with newly proposed improvements, an effective numerical method was successfully developed and applied to WEC arrays in various layouts. It was found that by arranging the layout in a more randomized manner, the optimal conditions for maximized power output can be challenging to reach, but the maximum power output can be increased to a higher level.
