| 摘 要： | 通过求解RANS方程计算船体周围粘性边界层，同时结合VOF方法处理自由表面，能够获得带自由表面的船体周围稳态粘性流场，但是难于比拟拖曳水池模型试验得到连续变化的流场，该文提出采用SPH流体仿真方法模拟船模阻力试验中自由表面及流场的生成与演化，并借助三维交互式图形显示技术实现试验过程的虚拟展现，最后以DTMB 5415船模试验加以例证。

| Abstract: | Steady viscous free-surface water flow around ship hull can be acquired by the combination of computing the viscous boundary layer around ship hull by solving the RANS equation and processing the free-surface with VOF method. But it is difficult to obtain continuous varying flow field as analogous to model test in towing tank. Simulating the generation and evolution of free-surface and flow field in ship model resistance test using SPH-based fluid simulation method and making a virtual presentation of the test procedure using three dimensional interactive graphics techniques are presented in this paper. Finally, DTMB 5415 ship model test is taken as an example. |
