Propagation Evolution Characteristics of Weakly Nonlinear Internal Solitary Waves on Slopes
Shanghai Jiaotong Daxue xuebao, 2021 The propagation equation of variable-coefficient internal solitary waves was used to describe the propagation and evolution of weakly nonlinear internal solitary waves (ISWs)on slopes with different slopes.

Rotation-induced nonlinear wavepackets in internal waves [PDF]
Physics of Fluids, 2014 The long time effect of weak rotation on an internal solitary wave is the decay into inertia-gravity waves and the eventual formation of a localised wavepacket. Here this initial value problem is considered within the context of the Ostrovsky, or the rotation-modified Korteweg-de Vries (KdV), equation and a numerical method for obtaining accurate ...

Kelvin-Helmholtz instability of relativistic jets - the transition from linear to nonlinear regime [PDF]
, 1997 The observed wiggles and knots in astrophysical jets as well as the curvilinear motion of radio emitting features are frequently interpreted as signatures of the Kelvin-Helmholtz (KH) instability (eg. Hardee 1987).

Amplification and suppression of internal waves by tides over variable bottom topography [PDF]
, 2006 The energy exchange between internal waves and barotropic currents over inclined bottom topography is studied theoretically and in the framework of the numerical model. The energy balance equation derived for a continuously stratified fluid predicts that

Advanced Functional Materials, EarlyView.This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Internal gravity waves: Analysis using the periodic, inverse scattering transform [PDF]
Nonlinear Processes in Geophysics, 1999 The discrete periodic inverse scattering transform (DPIST) has been shown to provide the salient features of nonlinear Fourier analysis for surface shallow water waves whose dynamics are governed by the Korteweg-de Vries (KdV) equation - (1) linear ...

Sound Field Fluctuations in Shallow Water in the Presence of Moving Nonlinear Internal Waves
Journal of Marine Science and Engineering, 2022 Fluctuations of sound intensity in the presence of moving nonlinear internal waves (NIWs) are studied. Prior works revealed the existence of peaks in the spectrum of these fluctuations due to mode coupling.

Nonlinear internal waves from the Luzon Strait [PDF]
Eos, Transactions American Geophysical Union, 2006 In the northeastern South China Sea, fast westward moving nonlinear internal waves (NLIWs) emanate nearly daily from the Luzon Strait during spring tide. Their propagation speed of about 2.9 meters per second is faster than NLIWs previously observed in the world's oceans.
