波浪对三维浮体的二阶作用

Second Order Wave Action on Floating Bodies

本文通过求解二阶势的方法对波浪与任意形状三维物体的相互作用问题做了研究。波浪运动的二阶势应用高阶边界元方法进行计算。为了高阶边界元方法的应用，本文给出了一个无速度势二阶空间导致，无奇异积分的新的积分方程。

The paper used a higher order boundary element method to deal with the calculation of the second orderpotential of waves radiated and diffracted from a floating body. For the ably integration related with body resPOnse, this paperderived a new formulation in which the singular P8rts of the spacial derivatives of the Green's function can be removed.Numerical experiment is also made in this paper. The comparison with published resultS on axisymmetric booties shows that thepresent method is satisfactory.
