A Study on Hydrodynamic Characteristics of Floating Wave-Breakers in finite Depth
Abstract
본 연구는 유한수심 영역에서 안정성과 소파성능이 우수한 쌍동형 부유식 소파구조물을 계획하기 위하여 단면형상의 변화, 부체간의 간격 변화 및 부가판 취부에 따른 유체역학적 특성을 쌍동형 모형선을 택하여 검토하였다.

본 연구결과 부체의 폭(a)에 대한 부체간의 간격(b)이 3, 즉 b/a=3일 때 보다 간격이 넓은 4일 때의 소파성능이 전반적으로 우수하게 나타났으며 부체의 형상변화에 대해 단면형상이 사다리꼴 모양으로 바깥쪽을 경사지게 한 경우가 소파성능이 우수하였다. 또한 수평부가판이 설치된 구조물의 소파성능이 전반적으로 좋아졌음을 알 수 있었다.
Recently Floating breakwaters have been used for wave control because it have advantages of sea water exchange function and so on. But we haven's had a exact solution about its performances yet, we also have a negative part of it - floating breakwaters must allow partial transmission of wave.

In this paper, three dimensional source distribution method to be applied in finite depth was developed and also experiments were carried out in order to know the performance of floating breakwaters.

Measured and computed studies were made in order to investigate the performance of breakwaters to various waves and several parameters, spacing of pintoons, geometry of structure, appendage plate.

It is found that transmission coefficients of floating breakwaters depend on the spacing f the pontoons, geometry of structure and appendage plate.
