研究開始時の研究の概要 |
The goal of achieving carbon neutrality around 2050 has raised great challenges to the global community. To substitute conventional fuels, new renewable energy resources need to be explored. The proposed research aims to resolve several essential hydrodynamic problems arised in ocean energy plants.

研究実績の概要 |
Ocean wave energy can be harnessed by a group of wave energy converters deployed together to generate electricity from the kinetic energy of ocean waves. Such wave energy arrays are often located near the coast or offshore, consisting of multiple devices, such as floating buoys, and connected to the grid through power transmission. In the present work, the multiple scattering theory is employed to assess the array performance in multi-directional irregular waves. Based on the meteorological occurrence probability of each sea state and the power matrix of each converter, the annual power production at a localised site is evaluated quantitively. Moreover, the developed numerical method is used to select the most appropriate site for given arrays considering the varying sea states in a year.

2: おおむね順調に進展している
理由
The project has been smoothly carried out. An effective method is developed to evaluate the annual power production of wave energy arrays at an arbitrary localised site. A series of physical findings are discovered and published in the prestigious journal Physics of Fluids. Another subsequent work is being summarised and will be submitted to Renewable Energy.

今後の研究の推進方策 |
Hydrodynamic issues related to the floating wind energy will be studied in the next year.
