摘要
应用源汇分布法通过理论分析与数值计算确定在波浪中航行的海洋结构物运动和遭遇设计荷载,对Green函数积分核中的奇点及其在特定计算域的高频震荡与增幅问题进行了数学处理;计算实例同有关试验结果的比较表明本计算结果达到工程应用精度.
Analytical and numerical investigation is made of the source potential for floating structure with forward speed in waves. A particular form is selected for numerical applications, where the double integral of Green function is transformed into single one and the oscillation characteristics for integrands in the certain computation domain is changed into smoothly and rapidly decreasing. Comparison of calculated examples with published data is given and it is shown that the numerical simulation is satisfactory with the engineering accuracy.
