Internal solitary wave bottom boundary layer dissipation

Physical Review Fluids, 2021
Bottom boundary layer instability enhances energy dissipation beneath shoaling internal solitary waves, leading to dissipation length scales of ~100 wavelengths.

Numerical study of internal solitary wave loads on a submerged slender body with multi-parameter coupling

The Physics of Fluids
This study investigates the destabilizing loads exerted on submarines by large-amplitude internal solitary waves (ISWs), which significantly increase the risk of a phenomenon known as “falling deep.” Using numerical simulations and theoretical analysis ...

Are Solitary Internal Waves Solitons?

Studies in Applied Mathematics, 1998
Results of fully nonlinear numerical simulations of the interaction of two mode‐1 solitary internal waves, both propagating in the same direction, are presented. After the interaction, two solitary internal waves emerge. The large wave is slightly larger than the initial large solitary wave, while the small one is slightly smaller than the initial ...

Coupled perturbed modes and internal solitary waves

The Journal of the Acoustical Society of America, 2003
Coupled perturbed mode theory combines conventional coupled modes and perturbation theory. The theory is used to directly calculate mode coupling in a range-dependent shallow water problem involving propagation through continental shelf internal solitary waves.

Atmospheric Internal Solitary Waves

2006
The solitary waves that have been observed in the atmosphere fall broadly into two classes: those that propagate in a fairly shallow stratified layer near the ground and those that occupy the entire troposphere. We present a survey of the observations of both types of solitary waves. The generation mechanisms differ substantially for these two types of

Nonlinear Wave Equations for Oceanic Internal Solitary Waves

Studies in Applied Mathematics, 2015
In the coastal ocean, the interaction of barotropic tidal currents with topographic features such as the continental shelf, sills in narrow straits, and bottom ridges are often observed to generate large amplitude, horizontally propagating internal solitary waves.

Internal solitary waves with subsurface cores

Journal of Fluid Mechanics, 2019
Large internal solitary waves with subsurface cores have recently been observed in the South China Sea. Here fully nonlinear solutions of the Dubreil–Jacotin–Long equation are used to study the conditions under which such cores exist. We find that the location of the cores, either at the surface or below the surface, is largely determined by the sign ...

Solitary internal waves in deep water

Journal of Fluid Mechanics, 1967
A new type of solitary wave motion in incompressible fluids of non-uniform density has been investigated experimentally and theoretically. If a fluid is stratified in such a manner that there are two layers of different density joined by a thin region in which the density varies continuously, this type of wave propagates along the density gradient ...

Internal Solitary Waves

1997
The basic theory of internal solitary waves is developed, with the main emphasis on environmental situations, such as the many occurrences of such waves in shallow coastal seas and in the atmospheric boundary layer. Commencing with the equations of motion for an inviscid, incompressible density-stratified fluid, we describe asymptotic reductions to ...

Breaking of shoaling internal solitary waves

Journal of Fluid Mechanics, 2010
The breaking of fully nonlinear internal solitary waves of depression shoaling upon a uniformly sloping boundary in a smoothed two-layer density field was investigated using high-resolution two-dimensional simulations. Our simulations were limited to narrow-crested waves, which are more common than broad-crested waves in geophysical flows.
