abstract:Based on the linear water wave theory, the scattering problem of obliquely incident water waves by submerged wavy plate is investigated in this paper. By applying the composite boundary element method (CBEM), the numerical results are presented to illustrate the effects of various wave incident angles, plate length, submerged depth of the plate, number of wavy shape, and the amplitude of wavy plate on the reflection and transmission coefficient. Computational solutions show that the two curves of the reflection and transmission coefficient incline to more oscillatory variation as the plate length increases. While the submerged depth of the plate decreases, the maximum peak of reflection coefficient and the minimum peak of transmission coefficient tend to smaller kh. Within the range of smaller kh, it is also found that the reflection coefficient increases as the amplitude or number of wavy shape of the plate increases. Finally, the submerged wavy plate could be the shoreline protection device as that of a submerged breakwater.
