摘要
双排圆筒防波堤是一种新型透空式防波结构,具有结构形式简单、利于水体交换、生态环境友好等优势,适用于软土地基海域的后方防护。双排圆筒防波堤利用前排桩、后排桩和后排挡浪板形成复杂的波浪掩护作用。为了研究该新型防波堤结构的消波性能,采用开源计算流体力学软件OpenFOAM,建立基于有限体积法和VOF模型的三维数值波浪水槽,开展了不同布置情况工况下的数值模拟。模拟结果表明,双排圆筒的消波性能受到前后排间距、前排圆筒间距等布置参数影响,模拟工况双排圆筒消波率在34%~50%。
The double-row cylindrical breakwater is a novel type permeable wave sheltering structure.It has simple structures and is favorable for water exchange and eco-environment.It is suitable for wave proofing in coastal areas with weak foundations.The double-row cylindrical breakwater forms wave hiding effect using the front cylinders,the rear cylinders and the rear wave baffles.In order to investigate the wave absorbing performance of the breakwater,open source CFD package OpenFOAM was utilized to establish the three-dimensional numerical wave tank with Finite Volume Method and VOF model.Numerical simulations were carried out for breakwaters with various configurations.Simulation results show that the wave damping performance is influenced by both the spacing between the front-row cylinders and the spacing between the front and the rear row cylinders.The damping ratio is from 34%to 50%for the simulation cases with double-row cylindrical breakwater.
