| 摘 要： | 采用N-S方程作为波浪场和孔隙流域的控制方程,应用有限差分方法对控制方程进行离散求解,采用VOF方法跟踪自由表面,反复迭代求解得到整个流域的压力场和速度场,并分析堤后渗透波高随入射波高、入射波周期的变化规律。最后结合波浪水槽物理模型试验验证本文所建立的数学模型,验证结果表明,此文所建立的数学模型可较好的模拟波浪与可渗防波堤的相互作用。

| Abstract: | A modified N-S equation has been used as a control equation for wave field and porous flow field.The control equations are discretized and solved by the finite-difference scheme,the free surface is tracked by the VOF method,and the pressure field and velocity field of the whole flow area have been solved by the reiterative iteration method.Finally,by comparing the results with that of the physical model test in wave flume,the numerical model established in this study are validated. |
