| Abstract: | The effectiveness of a submerged, bottom-mounted, flexible breakwater is investigated numerically. The structure is a horizontal, hemicylindrical shell filled with water. Potential flow is considered, and steady-state motions caused by monochromatic waves are studied. The three-dimensional response to normal and oblique waves is determined using the finite element method and a boundary integral method. Results are presented for a shell with a length of 150 m and a radius of 4 m, situated in water having a mean depth of 6 m. They indicate that the structure is effective in reducing the incident wave intensity over a wide range of frequencies. |
