Outline
A double-buoy floating breakwater and an oscillating buoy wave energy power converter were coupled into an integrated device. Based on the CFD technology, a numerical water tank was established to calculate and explore the energy capture efficiency and wave-dissipating performance of the integrated device. The results show that the floater motion in the cavity has strong nonlinearity. When the incident wave period is near the natural period of the cavity, the floater has the best energy capture efficiency, and the power generation and energy absorption efficiency can reach 2.4 times that of a single floater. In addition, the wave-dissipating performance of the integrated device is related to the wave steepness and the natural period of the structure. When the incident period is less than the natural period of the structure, the floating breakwater has a better wave dissipating effect on large steep waves; beyond the natural period, the floating breakwater will lose its excellent wave dissipation ability.
