首先探讨了浅水风浪数值模型—SWAN模型应用于模拟内陆湖泊风浪生成和传播变形时的特点。该模型存在不能有效地模拟近固壁边界处风浪场的缺点,以能正确地模拟湖区的风浪场和节约计算时间为原则,确定了计算范围。对太湖进行了风场和风浪...

基于吸收入射边界上反射波的方法,并通过将统一边界条件表达式推广到适应不规则波的情况,改进了非线性波传播的数值模型。将利用模型的线性版本(略去非线性项)所计算得到的台阶地形上波浪的反射和透射系数与相应的解析解进行了定量比较...

针对直接给定波浪入射边界条件时数值模型不能有效计算反射波的弊端,提出吸收入射边界上反射波的方法.该方法首先在离入射边界约1/2波长的范围内,计算入射波的理论解;然后将数值解减去理论解,得到真正反射波或由于数值累计误差所产生的...
