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

We apply the Hilbert transform to the physics of internal waves in two-dimensional fluids.
Using this demodulation technique, we can discriminate internal waves propagating in …

Based on linear inviscid theory, a two-dimensional source oscillating with frequency,
however, the transient evolution of nearly vertical beams takes place on a slower time scale …

Internal gravity waves propagate away from a localized monochromatic disturbance inside
beams, which develop around a St Andrew's Cross in two dimensions and around a double …

We present the first laboratory evidence of internal gravity wave tunnelling through weakly
stratified fluid patches and we derive analytic theories for energy transmission by the waves …

We present experimental results of the generation of internal gravity waves by a turbulent
buoyant plume im**ing upon the interface between a uniform density layer of fluid and a …

The background oriented Schlieren (BOS) technique has been applied to determine the
density field in an oblique shock-separated turbulent boundary flow. Measurements were …

Internal gravity wavetrains in continuously stratified fluids are generally unstable as a result
of resonant triad interactions which, in the inviscid limit, amplify short-scale perturbations …

The properties of waves generated by a vertically oscillating sphere in a uniformly stratified
fluid are examined both theoretically and experimentally. Existing predictions for the wave …

Oscillatory tides flowing over rough topography on the ocean floor generate internal gravity
waves, which are a major source of ocean mixing. Linear inviscid theory can describe waves …
