网衣对波浪传播影响的三维数值模拟

Three dimensional numerical simulation of the net effect on wave propagation

为研究网衣对波浪传播的影响,采用多孔介质模型模拟网衣,建立了模拟网衣与波浪相互作用的三维数值波浪水槽模型。基于该数值模型研究了波浪经过网衣作用后波高衰减的变化规律,并与物理模型试验结果进行比较。通过对比数值模拟和物理模型试验的结果,证明了该三维数值模型模拟网衣对波浪传播影响的可行性。

In order to study the net effects on wave propagation, a three-dimensional numerical wave tank was established, using a porous media model to simulate the nets. With the three-dimensional numerical model, the decrease of wave height through net panel was simulated, and the results of the numerical simulation were compared with the results in physical experiment. The comparison shows that wave transmission coefficient in numerical simulation agrees well with the data in physical experiment.
