Analytical and numerical investigation of nonlinear internal gravity waves [PDF]

open access: yesNonlinear Processes in Geophysics, 2001
The propagation of long, weakly nonlinear internal waves in a stratified gas is studied. Hydrodynamic equations for an ideal fluid with the perfect gas law describe the atmospheric gas behaviour. If we neglect the term Ͽ dw/dt (product of the density

Nonlinear Interactions of Two Incident Internal Waves [PDF]

open access: yes, 2016
We present experiments and analysis of the nonlinear interactions of two incident internal gravity wave beams of comparable amplitude. By using a wave maker consisting of a flexible boundary to a tank, driven by an array of independent actuators, incident beams of large amplitude several wavelengths in width are generated.

Observations of coherent transverse wakes in shoaling nonlinear internal waves

open access: yesJournal of Physical Oceanography, 2022
Space- and time-continuous seafloor temperature observations captured the three-dimensional structure of shoaling nonlinear internal waves (NLIWs) off of La Jolla, California.

An Effect of Electrokinetics Phenomena on Nonlinear Wave Propagation in Bubbly Liquids

open access: yesInternational Journal of Applied Mechanics and Engineering, 2021
A study of nonlinear waves in liquid-gas mixtures with the consideration of internal effects is an important problem of both the fundamental and the applied fluid mechanics.

Observation of internal tides, nonlinear internal waves and mixing in the Lombok Strait, Indonesia

open access: yesContinental Shelf Research, 2021
Lombok Strait is one of the main exit passages of the Indonesian throughflow (ITF), connecting the interior Indonesian seas with the Indian Ocean. Satellite images have shown that this strait is also the most remarkable zone of the Indonesian seas for ...

Conventional Partial and Complete Solutions of the Fundamental Equations of Fluid Mechanics in the Problem of Periodic Internal Waves with Accompanying Ligaments Generation

open access: yesMathematics, 2021
The problem of generating beams of periodic internal waves in a viscous, exponentially stratified fluid by a band oscillating along an inclined plane is considered by the methods of the theory of singular perturbations in the linear and weakly nonlinear ...

Observations of enhanced nonlinear instability in the surface reflection of internal tides [PDF]

open access: yes, 2013
Enhanced vertically standing waves formed by the superposition of two upward and downward going near-diurnal (D1) waves are observed during one semidiurnal (D2) spring tide in an approximately 75day long velocity record from the northeastern South China ...

Nonlinear Fate of Internal Wave Attractors [PDF]

open access: yesPhysical Review Letters, 2013
We present a laboratory study on the instability of internal wave attractors in a trapezoidal fluid domain filled with uniformly stratified fluid. Energy is injected into the system via standing-wave-type motion of a vertical wall. Attractors are found to be destroyed by parametric subharmonic instability (PSI) via a triadic resonance which is shown to

Simulations and observation of nonlinear internal waves on the continental shelf: Korteweg–de Vries and extended Korteweg–de Vries solutions [PDF]

open access: yesOcean Science, 2017
Numerical solutions of the Korteweg–de Vries (KdV) and extended Korteweg–de Vries (eKdV) equations are used to model the transformation of a sinusoidal internal tide as it propagates across the continental shelf.

Observations of Enhanced Sediment Transport by Nonlinear Internal Waves

open access: yesGeophysical Research Letters, 2020
The mechanisms responsible for sediment resuspension and transport by nonlinear internal waves (NLIWs) remain poorly understood largely due to a dearth of detailed field measurements. We present novel observations of the turbulent benthic boundary‐layer (
