“…Currently, many types of wave energy converters (WECs) have been developed, and each type of WEC has its own advantages and disadvantages. However, high power generation costs, low energy conversion efficiency, reliability and safety are still the fundamental reasons why these WECs are difficult to commercialize widely [7,8]. Considering several factors such as the power generation cost, total efficiency, reliability and safety, the oscillating buoy wave energy converter (OBWEC) has obvious advantages compared with other WECs.…”

The oscillating buoy wave energy converter (OBWEC) captures wave energy through the undulating movement of the buoy in the waves. In the process of capturing wave energy, the hydrodynamic performance of the buoy plays an important role. This paper designed the “Haida No. 1” OBWEC, in which the buoy adopts a form of swinging motion. In order to further improve the hydrodynamic performance of the buoy, a 2D numerical wave tank (NWT) model is established using ADINA software based on the working principle of the device. According to the motion equation of the buoy in the waves, the influence of the buoy shape, arm length, tilt angle, buoy draft, buoy width, wave height and Power Take-off (PTO) damping on the hydrodynamic performance of the buoy is studied. Finally, a series of physical experiments are performed on the device in a laboratory pool. The experimental results verify the consistency of the numerical results. The research results indicate that the energy conversion efficiency of the device can be improved by optimizing the hydrodynamic performance of the buoy. However, the absorption efficiency of a single buoy for wave energy is limited, so it is very difficult to achieve full absorption of wave energy.
