摘要:
采用解析方法研究了线性入射波作用下两层流体中多个圆柱形淹没浮体的波浪力特性。首先基于多极子展开方法,建立了散射势函数的解析表达式,并进一步得到浮体散射波浪力的计算公式,然后利用边界元方法验证了本文的解析解,最后分析了不同参数的变化对双圆柱形浮体结构波浪力的特有影响。

Abstract:
An analytical method is used to analyze the wave force of a long array of cylinders in a two-layer fluid acted by linear waves. The analytic expressions for the scattering potential functions are obtained by using the multipole expansion method, and expressions for the wave force are defined. A boundary element method is used to verify the correctness of the present analytical method. Finally, the analytical results of the wave force on cylinders are studied for some different parameters.
