Abstract
본 연구에서는 3차원 유동해석 수치모형인 OpenFOAM의 waves2Foam을 사용하여 무공케이슨 방파제의 전면이 피복되지 않은 조건과 테트라포드(TTP)로 피복된 조건에서 직립 케이슨에 작용하는 파압을 수치모의하고 수 리실험 결과와 비교하였다. 파압 수치모의 결과는 수리실험 결과와 상당히 잘 일치하였다. 이를 통해 테트라포드로 피복된 영역을 다공성 매체로 구현할 수 있는 경험식의 최적 파라미터 조합을 제시하였다.
In this study, waves2Foam implemented in OpenFOAM is used to simulate numerically the wave pressure on a verical caisson under the condition of with and without the placement of Tetrapods in front of the caisson. The comparisons of the numerical results and the experimental data show fairly good agreement between them. Based on this, it is possible to suggest an optimal combination of coefficients for an empirical formula to represent the protective TTP layer as porous media.
