部分浸没矩形结构波浪力的数值研究：平底上的长波
Numerical investigation of the wave force on a partially immersed rectangular structure: Long waves over a flat bottom
摘要：
本文介绍了从数值估计的长表面波上的固定和部分浸没的矩形结构所施加的力的结果。该主题与此类水工结构的设计、布置和操作决策的需要有关。在非线性势流模型的框架内模拟了波浪与结构物的相互作用。所获得的结果允许确定的水动力对一个单一的波的长度和振幅，长度和淹没的结构的依赖性。我们比较了不同初始波形下的结果，并考虑了作用在垂直墙和部分浸没结构上的力之间的差异。特别是，它表明，在相对较小的淹没的结构，较长的波影响它少，而在大的淹没和波墙相互作用的情况下，观察到相反的行为。
英文摘要：
This paper describes the results from a numerical estimation of the force exerted by long surface waves on a fixed and partially immersed rectangular structure. The topic is connected with the need of making decisions on the design, placement and operation of hydrotechnical structures of this kind. The wave-structure interaction is simulated in the framework of a nonlinear potential flow model. The results obtained allow to determine the dependence of the hydrodynamic force on the length and amplitude of a single wave, the length and submergence of the structure. We compare the results obtained for different initial wave shapes, and consider the differences between the forces acting on a vertical wall and a partially immersed structure. In particular, it is shown that at relatively small submergence of the structure, longer waves affect it less, while at large submergence and in the case of wave-wall interaction, the opposite behaviour is observed.
