动底兴波的线性理论

Linear theory of wave generation by a moving bottom

Denys Dutykh, Frédéric Dias, Youen Kervella

摘要:

长波在海洋中传播的计算显然依赖于初始条件。当波浪是由一个移动的底部,一个传统的方法包括在翻译的“冻结”的海床变形的自由表面和传播。本研究显示了经典的方法(被动生成)和主动生成之间的差异,其中包括底部运动。这里提出的解析解显示了被动发电的一些缺点。线性化的解决方案似乎是足够的考虑水波的生成由一个移动的底部。

英文摘要:

The computation of long wave propagation through the ocean obviously depends on the initial condition. When the waves are generated by a moving bottom, a traditional approach consists in translating the ``frozen'' sea bed deformation to the free surface and propagating it. The present study shows the differences between the classical approach (passive generation) and the active generation where the bottom motion is included. The analytical solutions presented here exhibit some of the drawbacks of passive generation. The linearized solutions seem to be sufficient to consider the generation of water waves by a moving bottom.
