Abstract

The traditional rectangular floating breakwater has simple structure and convenient installation, but its effect on long wave attenuation is limited; In order to effectively improve the wave attenuation performance of this kind of floating breakwater, a new type of floating breakwater structure with triangular wing plate is proposed in this paper. Firstly, based on the viscous incompressible fluid dynamics theory, the fluid-structure interaction numerical model of floating breakwater was established, and its applicability and feasibility were verified by comparing with the published results; Then, the wave attenuation performance of the new breakwater was numerically analyzed under different wave conditions. The calculation results showed that the wave attenuation performance reached the optimal value when the wing angle is 22.5 °; On this basis, the influence of different box draught on the wave attenuation effect was further analyzed. The analysis results of the vorticity field and velocity field showed that the wave attenuation performance of the floating breakwater with triangular wing plates is significantly better than that of the traditional rectangular floating breakwater because it not only reduces the transmitted waves through the reflection of the wing plates, but also effectively dissipates the incident wave energy through the formation of eddy. The new breakwater structure proposed in this paper can provide some reference for the application of wave attenuation in practical engineering.
