Wave dissipation performance of tripod-shaped floating breakwater
To further improve the wave dissipation performance of rectangular floating breakwater,a tripod-shaped floating breakwater is designed.A two-dimensional numerical model is established based on STAR-CCM+software to analyze the influence of draught depth,arc wall height and arc wall angle on the wave dissipation performance of the structure.The results show that compared with the rectangular box floating breakwater,the tripod-shaped floating breakwater can effectively improve the wave dissipation performance,and the transmission coefficient decreases with the increase of draught depth,arc wall height and arc wall angle.The reflection coefficient increases with the increase of the draught depth and the height of the arc wall,while the influence of the arc wall angle on the reflection coefficient is not obvious,the reflection coefficient increases with the increase of relative width.Under the conditions of wave elements studied,when the structural parameters are set to draught depth 0.2 m,arc wall height 0.05 m and arc wall angle 54 °,the transmission coefficient and reflection coefficient reach 0.11 and 0.61 respectively,in this case,the optimal parameters are set,and the wave dissipation performance of floating breakwater is the best.
