| 摘 要： | 通过数值模拟分析了波浪谱形对不规则波浪数值模拟结果的影响.采用不同参数的JONSWAP谱模拟入射波要素,基于抛物型缓坡方程模拟不规则波浪的传播,分析了波浪谱形状对波浪数值模拟结果的影响.结果表明,采用抛物型缓坡方程模拟不规则波浪时,入射波浪谱形对模拟结果影响不明显;但由于模型中非线性项的影响,采用不规则波模拟的波高分布和采用规则波模拟的结果略有差别.

| Abstract: | The impact of the wave spectrum shape on the numerical simulation of irregu- lar waves is analyzed. The JONSWAP spectrum with different parameters is applied to simulate the distributions of irregular incident waves and the propagation of the irregular waves is modeled based on the parabolic mild slope equation. The numerical results show that the shape of incident wave spectrum has little influence on the simulation of irregular waves when the parabolic mild slope equation is used, but the distribution of wave height simulated with the irregular waves differs slightly from those simulated with regular waves due to the influence of non-linear terms in the model. |
