Dynamic Response Analysis of Pressurized Air Chamber Breakwater Mounted Wave-Power Generation System Utilizing Oscillating Water Column

With the increasing demand for renewable energy in the world, research contributing to the improvement of the technology level of wave power generation is essential. The authors have been developed a wave power generation system using port facilities in inner bays with high energy-consuming cities. In this study, the relationship between the rotational characteristics of a Savonius water turbine and the water particle velocity was quantitatively evaluated under the calm conditions of the inner bay, such as wave motion, flow, and coexistence of wave and current. According to the experimental results, it is found that the relationship between the rotational circumferential speed and the water particle velocity of the water turbine installed in a wave field tends to be different from that in a flow field and is evaluated by different equations. In addition, the relationship between circumferential velocity and the water particle velocity has also been formulated when installed in a wave-current coexistence field.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/KX0XBFuao48

Effective Use

Abstract As industrialization, worldwide population growth, and improvements in the living standards in developing countries continue, demands for energy, food, and water, likewise surge. This in turn accelerates global warming, and its resultant extreme weather effects. Among the measures proposed to meet the growing energy demands, the use of renewable energy is gaining more and more attention. In particular, wave power generation is attracting a great deal of attention as an effective use of ocean energy. However, current wave generators are large and very expensive relative to their output. Furthermore, they cannot generate power efficiently with wave directivity, small amplitude waves and so on. For these reasons, widespread use is very limited. In order to solve these problems, this paper discusses the possibility of a recently developed wave power generator that uses a newly developed dielectric elastomer (DE) as a new way to harvest renewable energy. We also discuss the technical breakthrough of building a mega power generation system using DEs.
