초록

본 연구에서는 OpenFOAM 기반의 부유식 연직판의 파랑 저감 성능 평가 수치해석 모델링을 수행하였다. Waves2FOAM 라이브러리를 기반으로 내부조파에 의한 파랑 생성 및 스폰지층에 의한 소파 기능을 추가로 적용하였다. 이렇게 추가된 조파 및 소파 기능을 먼저 간단한 2차원 해석으로 검증한 후, Briggs et al.(2001)의 규칙파 실험자료 2가지에 대한 수치모델링을 수행하였다. 모델링 결과는 실험자료와 대체로 잘 일치하였으며, Briggs et al.(2001)에 수록된 WAMIT 수치해석 결과보다 더 좋은 결과를 나타내었다.

This study performed an OpenFOAM-based numerical modeling for simulating performance of wave reduction by a floating vertical plate. Based on the Waves2FOAM library, an internal wave generation and energy dissipation with sponge layers schemes were further implemented. The performance of wave generation and dissipation was first tested with a simple two-dimensional analysis. Then, numerical simulation was carried out with the experimental data of Briggs et al. (2001) for the two regular wave cases. In general, the modeling results agreed well with the experimental data, showing better agreement than the numerical analysis by WAMIT that is included in Briggs et al. (2001).
