规则波在岛礁浅海区传播的数值模拟

Numerical Simulation for Regular Wave Propagation along Shallow Sea of Reef

针对岛礁浅海区的复杂地形和波浪环境,通过求解Boussinesq方程,结合区域源造波法,对规则波的传播和演化进行数值模拟,数值计算结果与已有模型试验对比表明,监测点波高计算值与模型试验值总体吻合较好。采用数学插值方法,建立岛礁实际复杂地形的数学模型,对岛礁实际波浪环境进行预报,能够为岛礁浮式平台设计提供波浪环境输入。

For the complication submarine topography and wave condition,the numerical simulation for regular wave propagation along shallow sea of reef was carried out by solving Boussinesq＇s equation with numerical wave generation. The comparison between numerical simulation results and test results indicated that the wave height in the most of monitoring points closely matched. The mathematical model of the real complicated topography was established by interpolation method,and the wave condition was predicted. The numerical simulation method can provide wave condition for offshore floating structure.
