三维淹没水平板上的孤立波载荷:数值计算及与实验的比较

Solitary-wave loads on a three-dimensional submerged horizontal plate: Numerical computations and comparison with experiments

T. Geng, H. Liu, F. Dias

摘要:

在势流假设下,采用三维边界元法模拟了孤立波与三维水下平板的相互作用。数值设置密切遵循最近在上海交通大学进行的实验室实验的设置。数值计算结果与实验结果进行了比较。二维波高、作用在板上的水平力和垂直力以及纵摇力矩总体上一致。尽管存在一些差异,但比较表明,使用三维边界元法求解具有自由表面的完全非线性势流方程的模型可以令人满意地捕捉到非线性波与水下水平板之间相互作用的主要特征。

英文摘要:

A parallelized three-dimensional (3D) boundary element method is used to simulate the interaction between an incoming solitary wave and a 3D submerged horizontal plate under the assumption of potential flow. The numerical setup follows closely the setup of laboratory experiments recently performed at Shanghai Jiao Tong University. The numerical results are compared with the experimental results. An overall good agreement is found for the two-dimensional wave elevation, the horizontal force and the vertical force exerted on the plate, and the pitching moment. Even though there are some discrepancies, the comparison shows that a model solving the fully nonlinear potential flow equations with a free surface using a 3D boundary element method can satisfactorily capture the main features of the interaction between nonlinear waves and a submerged horizontal plate.
