含入射波时任意三维浮体之全非线性流场模拟

应用DELTA方法之数值模型于仿真分析船舶在有入射波海域航行时的流场，并对该运动所产生的波形加以分析。DELTA方法的特点是将所有奇点布置于计算区域之外，相对于传统做法而言，程式的复杂度减低，运算过程所需的时间亦减少。文中使用造波器来仿真真实海面之波浪情形，来仿真海面的波浪。当三维入射波被导人计算区域之中后，即可以此数值模型仿真船舶航行于类真实海面的情形；最后将船体的波形与相关文献进行比较，其结果是令人满意的。

Simulations of fully nonlinear flow with incident waves for arbitrary 3-D floating bodies

The DELTA method is applied to simulate the waves generated by ships. The DELTA Method reduces the complexitics of the program and shortens the computation time because all the singularities are placed outside of the computational domain and Cauchy intcgral is then avoided. A wedge-shape wave maker is used to generate incoming waves to simulate the real sea conditions. When 3-D incoming waves are introduced into the computational domain, the fluid fleld of a ship sailing in real seas is simulated. The numerical results are then compared with the published results. The comparisons show that the DELTA method is stable and reliable.
