基于滤波纳维-斯托克斯方程和斯马戈林斯基湍流模型，开发了数值波水槽来研究不规则波浪越过光滑海堤的越顶过程。对海堤上的全非线性驻波和规则波的爬升进行了模拟，以验证带有波浪发生和吸收模块的数值水槽的实施。为了模拟平稳遍历随机过程，针对每个指定的不规则波谱计算具有不同随机种子的几种情况。结果表明，统计平均溢流流量与经验公式、其他数值结果和实验数据具有良好的一致性。
Based on the filtered Navier-Stokes equations and Smagorinsky turbulence model, a numerical wave flume is developed to investigate the overtopping process of irregular waves over smooth sea dikes. Simulations of fully nonlinear standing wave and regular wave’s run-up on a sea dike are carried out to validate the implementation of the numerical wave flume with wave generation and absorbing modules. To model stationary ergodic stochastic processes, several cases with different random seeds are computed for each specified irregular wave spectrum. It turns out that the statistical mean overtopping discharge shows good agreement with empirical formulas, other numerical results and experimental data.
