Sensors, 2021 We have built a Fizeau fiber interferometer to investigate the internal cylindrical defects in an aluminum plate based on laser ultrasonic techniques. The ultrasound is excited in the plate by a Q-switched Nd:YAG laser. When the ultrasonic waves interact

Examining Breaking Internal Waves on a Shelf Slope Using Numerical Simulations [PDF]
Oceanography, 2012 The subject of internal waves interacting with bottom topographic features in the ocean has received much attention in the past few decades. This heightened interest is mainly due to a conjecture that breaking internal waves at boundaries can be a ...

Large eddy simulation and laboratory experiments on the decay of grid wakes in strongly stratified flows [PDF]
, 2009 A detailed analysis of the flow structure resulting from the combination of turbulence and internal waves is carried out and visualized by means of the Schlieren method on waves in a strongly stratified fluid at the Laboratory of the IPM in Moscow. The

A Model Sensitivity Study of Ocean Surface Wave Modulation Induced by Internal Waves
Earth and Space Science, 2022 Nonlinear internal waves are an upper ocean phenomenon that drives horizontal surface current gradients, which in turn modulate ocean surface waves. Under certain conditions, this wave‐current interaction creates ocean surface roughness heterogeneity, in

An Introduction to the Special Issue on Internal Waves [PDF]
Oceanography, 2012 This special issue of Oceanography presents a survey of recent work on internal waves in the ocean. The undersea analogue to the surface waves we see breaking on beaches, internal waves play an important role in transferring heat, energy, and momentum in

Variability of Internal Wave Strain Over the Western Boundary Region in the North Atlantic
Frontiers in Earth Science, 2022 Based on the CTD profiles and mooring measurements of the Line W program in the North Atlantic about 35°N/70°W, we investigated the spatial variability of internal wave-induced strain variance along the Line W section and the associated reasons.

Angular Momentum Transport via Internal Gravity Waves in Evolving Stars [PDF]
, 2014 Recent asteroseismic advances have allowed for direct measurements of the internal rotation rates of many sub-giant and red giant stars. Unlike the nearly rigidly rotating Sun, these evolved stars contain radiative cores that spin faster than their ...

Internal Waves on the Washington Continental Shelf [PDF]
Oceanography, 2012 The low-frequency oceanography of the Washington continental shelf has been studied in great detail over the last several decades owing in part to its high productivity but relatively weak upwelling winds compared to other systems.

Noise of Internal Solitary Waves Measured by Mooring-Mounted Hydrophone Array in the South China Sea
Journal of Marine Science and Engineering, 2022 Internal solitary waves in the South China Sea have attracted attention because of their large amplitude and high rate of occurrence. Internal solitary waves have a substantial influence on underwater sound propagation and ambient noise.

Shear induced breaking of large internal solitary waves [PDF]
, 2009 The stability properties of 24 experimentally generated internal solitary waves (ISWs) of extremely large amplitude, all with minimum Richardson number less than 1/4, are investigated.
