Abstract:The scaled boundary finite element method (SBFEM) is a novel semi-analytical technique, combining the advantage of the finite element method (FEM) and the boundary element method (BEM) with unique properties of its own. In this paper, the SBFEM is used for computing wave passing a submerged breakwater, and the reflection coefficient and the transmission coefficient are given for the case of wave passing by a rectangular submerged breakwater and a rigid submerged barrier breakwater in a constant water depth. The results are compared with the analytical solution and experimental results. Good agreement is observed. Through compared with the results using the dual boundary element method (DBEM), it is found that the SBFEM could obtain the higher accuracy with fewer elements. Many submerged breakwaters with different demission are computed by the SBFEM, and the changing character of the reflection coefficient and the transmission coefficient are given in the current study.
