Abstract
This study used computational fluid dynamics (CFD) to analyze the performances of an air-blower wave power generation device with buoy wave energy converter, and simulated the process of waves acting on the double buoys to produce vertical kinetic energy and subsequently applying the energy to an ocean wave electricity generator set to generate electricity. Notably, we can compute the average power based on the movement and output force of buoy over a period of time. The parameters of buoys are the same with a diameter 2 m and height of 3 m in the vertical direction. Here the wave height is 0.6, 0.8 and 1 m, the wave period is 3 to 6 sec, and the range of gaps between the buoys is about 0.5 to 3 m. The power output of two buoys was calculated when various conditions of waves act on the buoys, and the numerical analysis of the front and back buoys was performed.
