利用格林定理和移动脉动源建立了一个积分方程方法 ,并利用高阶方法对积分方程进行了离散和求解 ,用于计算波浪和水流在浅滩上发生的绕射现象 .作为算例 ,应用这一方法对波浪在回转抛物形浅滩周围和流场作用下的波高分布做了计算 ,得到了水流对波浪绕射的影响关系 ,其计算结果可作为其他流场中波浪绕射的简化数值模拟方法的比较基准 An integral equation method is established by using Green’s theorem and mobile pulsation source, and the integral equation is discretized and solved by a higher-order method to calculate the diffraction phenomenon of wave and water flow on the shoal. As an example, The wave height distribution of the wave around the parabolic shoal and the flow field is calculated and the influence of water flow on the diffraction of the wave is obtained. The calculated result can be used as a simplified numerical simulation method for wave diffraction in other flow fields Baseline
