碩士 / 國立高雄海洋科技大學 / 海事資訊科技研究所 / 104 / This study used computational fluid dynamics to analyze the performance of an air-blower wave power generation device with buoy wave energy converter, and simulated the process of waves acting on the buoys to produce vertical kinetic energy and subsequently applying the energy to an ocean wave electricity generator set to generate electricity. The movement of buoy motion in the vertical direction can produce a stable output of power into the cylinder, then the pressurizer is intended to perform the output power of stabilization successfully and smoothly. This study used different sizes of composite buoys for simulation to determine the various size of and space between the front and back buoys. In the numerical simulation, the wave height was set to be 1 m, the wave period was 6 sec, and the various gaps between the buoys were used. This study analyzed and compared situations when waves with various conditions hit the buoys, and the power generated by the front buoy was more desirable than that generated by the back buoy. Future studies can design various forms of buoys for simulation and comparison to determine the most stable and efficient buoy for ocean wave electricity generation. Regarding the computation of the interaction between waves and buoys, the design of the buoy shape and the hydrodynamic calculation such as movement displacement and force can be analyzed and compared. The better buoy design contributed to efficient ocean wave electricity generation, and the numerical simulation performed in this study served as a satisfactory approach for designing buoy parameters. According to the simulation analysis, the average power can be calculated using the movement and force output of the buoys. This study integrated fluid mechanics and the hydrodynamic analysis of waves and can be a reference for future researchers to design composite ocean wave electricity generation equipment for commercial use.
After the results obtained of computation, the diameter of buoy equal to 3 meters for power output of the sea wave power generation is more efficiency comparing with other cases. The interactions of interference flow decrease with the gap ratio between the cylinders increase. The staggered and arrayed arrangements of 8 buoys and 9 buoys are similar for power output.
