摘要
通过在二维数值水槽内用边界元法直接求解Laplace方程,对规则波在缓坡上的变形及破碎进行了数值计算。分析了不同底坡及采用不同底摩阻系数时规则波的破碎特征,并对规则波破碎的极限坡度进行了研究。重点分析了规则波破碎时海底坡度、底摩阻系数及波形不对称性对破碎指标的影响。
Based on the resolution of Laplace Equation in numerical tank by BEM method, numerical simulation of regular wave deformation and breaking on gentle slope is conducted. The breaking wave characteristics on different slopes With various bottom friction coefficients are analyzod, and the critical slopes influenced by bottom friction coefficients and the effects of wave asymmetry on breaker indices are analyzed in detail.
