Abstract

The numerical investigations on the wave-screening characteristics of floating breakwaters are presented. The fluid motion is idealized as linearized, two dimensional potential flow. A finite element model is adopted to analyze the performance of floating breakwaters. Numerical experiments are carried out for two type floating breakwater. One is a conventional pontoon type breakwater with rectangular cross-section, and the other is a side float breakwater which consists of two rectangular shaped floats connected to each other by a frame. To improve the performance of the floating breakwaters, especially for long-period wave conditions, numerical experiments are carried out for the cases attaching the thin plates at the bottom of folats in the vertical direction.

본 논문은 2차원 유한요소모델을 이용한 부유식 방파제의 파랑차단특성에 대한 수치적 연구이다. 유체영역은 선형화된 2차원유동으로 가정하고, 부유식 방파제의 성능을 분석하기 위하여 유한요소법을 적용하였다. 상자형 부유식 방파제와 두 개의 상자가 일정한 간격으로 양측 방파제를 대상으로 파랑차단효과 대한 수치해석을 실시하였다. 긴 주기 파랑의 차단효과를 증대시키기 위한 방안 중의 하나로 연직판을 부체 하단에 양측에 부착한 경우에 대한 수치실험을 실시하였다.
