摘要
浮式防波堤具有成本低、安装方便、可移动性强的优势,越来越受到行业的关注。该文提出了一种倒π新型浮式防波堤。基于N-S方程,选用Standard k-ω紊流模型,应用商用计算流体软件STAR-CCM+,建立了波浪中浮式防波堤消波仿真的二维数值模拟方法,并与试验结果对比,验证了计算模型的可行性。利用建立的计算模型分析了倒π型浮式防波堤在不同波浪周期和两种水深环境下消浪效果,结果表明:该文提出的消波效果明显好于矩形防波堤。随着波浪周期和水深的减少,消波效果增强。当波浪周期不大于6 s时,倒π型防波堤的消浪效果大于50%。该文提出的新型浮式防波堤可作为海上消波堤的一种选择。
he floating breakwater has the advantages of low cost,easy installation and mobility,and is getting more and more attention from the industry.In this paper,a new floating breakwater of invertedπ-type is proposed.Based on the N-S equation,the Standard k-ωturbulent flow model is selected,and the commercial computational fluid software STAR-CCM+is applied to establish a two-dimensional numerical simulation method for wave dissipation simulation of floating breakwaters in waves,and the feasibility of the computational model is verified by comparing with the experimental results.The wave dissipation effect of the invertedπ-type floating breakwater under the conditions of different wave periods and two water depths is analyzed using the established computational model.The results show that the wave dissipation effect proposed in the paper is significantly better than that of the rectangular breakwater.With the reduction of wave period and water depth,the wave dissipation effect is enhanced.When the wave period is not more than 6s,the wave dissipation effect of invertedπ-type breakwater is greater than 50%.The new floating breakwater proposed in this paper can be used as an alternative for marine breakwaters.
