摘要
基于线性势流理论，推导了有限水深中圆柱形月池辐射问题的解析解。首先利用分离变量法，以包含未知系数和贝塞尔函数的无限序列的形式给出了流场中辐射速度势的表达式；然后通过边界条件建立方程组，进而求解未知系数。计算了圆柱形月池的附加质量、阻尼系数，发现了月池内部的共振现象。
Based on the linear potential theory, an analytical solution is presented to study the radiation problem of a cylindrical moon pool on the surface of water with finite depth, The method of separation variation is employed to obtain the radiation wave potential in the form of infinite series of the Bessel functions with the unknown coefficients which can be determined by solving a set of linear equations from the boundary conditions. The added mass and damping coefficients of the cylindrical moon pool are calculated and the resonant phenomena are investigated.
