The interaction of the solitary wave with an oil platform composed of four vertical circular cylinders is investigated for two attack angle of the solitary wave (square arrangement) and (diamond arrangement). The solitary wave is generated using an internal source line as proposed by Hafsia et al. (2009). This generation method is extended to three-dimensional wave flow and is integrated into the PHOENICS code. The volume of fluid approach is used to capture the free surface evolution. The present model is validated in the case of a solitary wave propagating on a flat bottom for where is the wave height and is the water depth. Compared to the analytical solution, the pseudowavelength and the wave crest are well reproduced. For a solitary wave interacting with square and diamond cylinders, the simulated results show that the maximum run-ups are well reproduced. For the diamond arrangements, the diffraction process seems to not affect the maximum run-ups, which approached the isolated cylinder. For the square arrangement, the shielding effect leads to a maximum wave force more pronounced for the upstream cylinder array.

方形和菱形排列的海上石油平台的三维模拟

针对孤波的两个迎角，研究了孤波与由四个垂直圆柱组成的油平台的相互作用。 （方形排列）和 （钻石排列）。孤波是使用Hafsia等人提出的内部源线生成的。（2009）。这种生成方法扩展到了三维波流，并集成到了PHOENICS代码中。流体量法用于捕获自由表面演化。本模型在孤波在平板底部传播的情况下得到验证。浪高在哪里，水深在哪里。与解析解相比，伪波长和波峰都能很好地再现。对于与方形和菱形圆柱相互作用的孤立波，模拟结果表明可以很好地再现最大的上升。对于菱形排列，衍射过程似乎不会影响接近隔离圆柱体的最大加速时间。对于正方形布置，屏蔽效果导致对于上游圆柱阵列更明显的最大波浪力。
