摘要:

为了形象地说明内波的传播模式，研究给出了内波水槽中由半板造波所形成的内波解。结合Vaisala频率N(z）＝const和简化Holmboe两种密度剖面模式讨论了内波场的传播图案。在内波水槽中成功地形成了上述两种密度剖面，相应的实验印证了本文分析的正确性。

Abstract:

In order to illustrate the propagation mode of internal wave, a solution of internal wave generated by a semi-plate wave maker in water channel is presented in this paper. The internal wave filed image for two density modes profile with Vaisala frequency N(z)=const and simplified Holmboe distribution is discussed. The particle path and pressure distribution of fluid are analyzed. Both of density modes profile above mentioned has been formed successfully in the internal wave water channel of the Physical Oceanography Laboratory of Ocean University of Qingdao. The relevant experiments clearly confirm the analyses in this paper. The photo of internal wave field generated by semi-plate wave maker shows the internal wave is out of phase along vertical direction, which different with that is in phase generated by the whole plate wave maker.

Key words: Stratified fluid, Internal wave, Wave maker
