... waves generated by a sphere towed in a stratified fluid were presented by Hopfinger (1991), Chomaz (1991) and Bonneton (1993). They analyzed the internal waves and turbulence waves using the fluorescent dye technique. Recently, some researchers used computational fluid dynamics (CFD) methodology...

... proportional to the square root of gravity, the amplitude of internal wave can be 20-30 times of water wave under the same energy condition (Li, 2015). This is the essential difference between internal waves and water waves. Internal solitary wave is a kind of non-linear large amplitude internal wave...

... are studied to assess the influences of the stratification. Results show that internal waves are generated by the presence of the sphere in stratified fluid, which results in an increase in resistance. The vertical motions and vortices are suppressed due to the stratification in vertical direction compared...

... ABSTRACT In order to study the interaction between the internal waves (IWs) and the surface waves (SWs) with different periods over a slope-shelf, laboratory experiments and numerical simulations by using plunger wave maker are conducted in the paper. Laboratory results reveal that the wave...

... parameters are analyzed and compared with the existing empirical relations. The energy dissipation during wave propagation is investigated. We find that the attenuation rate of amplitude and energy of ISWs decrease as η 0 increases, however, this trend tends to flatten as the internal wave amplitude...

... are derived from wave break. INTRODUCTION The internal wave is one of the complex environmental disasters threatening the safe of offshore structures. As a typical internal wave, the internal solitary waves can propagate over a long distance in oceans with the same waveform. This property of the internal...
