Abstract:Boussinesq类水波模型在港口、海岸以及海洋工程领域应用广泛,但以前对这类模型的变浅性能的研究不够充分.针对Madsen和Schaffer
提出的一组四阶Boussinesq方程,从理论和数值两个方面对这一问题进行了探讨.理论分析了其变浅性能,指出该文献中参数alpha_2和beta
_2的取值是不合理的,并重新确定其取值.在交错网格下建立了基于混合4阶Adams-Bashforth-Moulton格式的预报-校正数值模型.数
值模拟了两个典型算例:一是缓变平坡地形上波浪的传播变形,二是波浪在淹没梯形潜堤上的波浪演化过程.计算结果分别与解析结果、物理模型实验结果进行了比
较,发现变浅系数的取值对数值结果影响很大,新参数比原文参数模拟结果的吻合程度更高,这佐证了理论分析.
