基于波能守恒方程对平直斜坡上近岸波浪场以及近岸波浪斜向入射破碎后所产生的沿岸流场进行数值模拟.鉴于平直斜坡地形较简单,便于简单计算,利用基于波能守恒方程建立的波浪场数学模型计算得到波高的变化,从而利用Longuet-Higgins计算辐射应力.在此基础上,利用近岸波流场数学模型对实验波况下的波流场进行模拟,并将数值模拟结果与实验结果进行比较.结果表明,该模型可以很好地模拟近岸波流场.
Based on the wave energy conservation equation, the numerical simulation of coastal flow field generated by the steep slope near-shore wave field and the nearshore wave obliquely incident broken is given. Because the straight slope topography is relatively simple and easy to calculate, Equation was used to calculate the wave height, and the Longuet-Higgins method was used to calculate the radiation stress. Based on this, the wave field in the experimental wave field was simulated by the mathematical model of nearshore wave field, and the numerical value The simulation results are compared with the experimental results. The results show that the model can simulate the nearshore wave field well.
