For a nonuniformly stratified layer of fluid, internal gravity waves propagate at varying angles
depending on the local buoyancy and Coriolis (in geophysical applications) frequencies …

Reflecting internal gravity waves in a stratified fluid preserve their frequency and thus their
angle with the gravitational direction. At boundaries that are neither horizontal nor vertical …

Internal gravity waves are a key process linking the large-scale mechanical forcing of the
oceans to small-scale turbulence and mixing. In this review, we focus on internal waves …

Motivated by observations of turbulence in the strongly stratified ocean thermocline, we use
direct numerical simulations to investigate the interaction of a sinusoidal shear flow and a …

The comprehension of stratified flows is important for geophysical and astrophysical
applications. The weak wave turbulence theory aims to provide a statistical description of …

In this paper we solve two initial value problems for two-dimensional internal gravity waves.
The waves are contained in a uniformly stratified, square-shaped domain whose sidewalls …

Internal waves are ubiquitous in the ocean and play an essential role in the transport of
energy and mixing. Their peculiar reflection enables the concentration of energy on a limit …

Natural and externally-forced excitation of internal gravity waves in a uniformly stratified fluid
have been thoroughly investigated by means of highly resolved large eddy simulations. The …

Stratified and rotating fluids support obliquely propagating internal waves. A symmetry-
breaking shape of the fluid domain focuses them on a wave attractor. For a trapezoidal …

We present laboratory experiments on turbulence in a linearly stratified fluid driven by an
ensemble of internal gravity waves which approaches statistical homogeneity and …
