| Research Abstract |
This project aims to systematize the occurrence condition of fluid resonance in narrow joint gaps of coastal and ocean structures for example caisson-type coastal structures and the amplification of wave height in the gaps under actual water wave condition. The occurrence such as resonant phenomena has been reported as unique phenomena in very narrow area compared with the typical structure's length. In this study, we develop our research works based on the knowledge about the characteristic on fluid resonance due to orthogonal regular incident wave. The effects of incident wave angle and irregularity of incident wave are shown experimentally, and the theoretical model is constructed to systematize the occurrence condition of fluid resonance and the amplification of wave height in the gaps.
