摘要
基于深水时域格林函数的数值处理方法及开发的计算程序,采用三维时域数值模拟方法,在线性势流理论框架内对深海波浪中航行船舶的辐射问题和绕射问题进行了求解,研究探讨了航行船舶与波浪相互作用问题。研究中对不同航行速度的Wigley型船水动力系数和波浪力进行了数值计算,通过与试验及文献计算结果的比较,验证了三维时域数值计算程序的有效性。
A 3D time domain program based on time domain Green＇s function has been further developed to simulate the interaction between waves and ships with forward speed. The radiation and the diffraction problems of a Wigley-hull-form ship at different forward speed were discussed, and the hydrodynamic coefficients and wave torces were computed to verify the accuracy and reliability of the 3D time domain program. The numerical results agree well with the experimental and reference results.
