PIV를 이용한 파랑 중 고정 구조물 주위의 유동해석

Abstract

The purpose of this study is to provide a basic foundation to select a maximum wave force when the ocean structure is laid out, an experiment was conducted by using a cylinder model that was designed for a reduced scale.

First, the experiments were performed by changing maximum wave slopes in regular wave conditions. In addition, the further experiment by changing the cylinder's diameter was conducted.

Furthermore, the experiments were also conducted to select a maximum wave force directly after the wave breaking in irregular wave conditions. More importantly, the results of this experimental study were compared with the theoretical results from literature.

Further investigations will be needed to confirm the present results, regarding to the flow structure around the fixed body(cylinder) in breaking wave(irregular wave). For the future research, a comparative study will be recommended between results of the cylinder model and results of the regular wave model.
