摘要：

A rotating buoy wave energy capture device was proposed, and a series of physical model tests were carried out to study its hydrodynamic behavior under regular waves. The experimental results show that: (1) The angular velocity of rotational buoy decreases with the increase of the pitch of screw. (2) When the period of the incident wave is smaller than 2.4 s, the average angular velocity increases with the increase of wave period; When the period of the incident wave is higher than 2.4 s, the increasing amplitude of average angular velocity decreases with the increase of wave period, and even the average angular velocity decreases for a small proportion of scenarios. (3) The capture width ratio is basically positively correlated with the wave period. The capture width ratio increases with the decrease of the pitch of screw. When δ=0.02 and T=2.4 s, the capture width ratio reaches the maximum value of 22.65%. Finally, the dimensional analysis method was used to derive the average angular velocity equation, which is verified well by the experimental data. © 2022, Solar Energy Periodical Office Co., Ltd.
