Solitary waves on a vorticity layer

open access: yesJournal of Fluid Mechanics, 1994
Contour dynamics methods are used to determine the shapes and speeds of planar, steadily propagating, solitary waves on a two-dimensional layer of uniform vorticity adjacent to a free-slip plane wall in an, otherwise irrotational, unbounded incompressible fluid, as well as of axisymmetric solitary waves propagating on a tube of azimuthal vorticity ...

Multi-soliton energy transport in anharmonic lattices

open access: yes, 2000
We demonstrate the existence of dynamically stable multihump solitary waves in polaron-type models describing interaction of envelope and lattice excitations. In comparison with the earlier theory of multihump optical solitons [see Phys. Rev. Lett.

Research Progress on Mechanical Characteristics of Vertical Cylinders under Internal Solitary Waves

open access: yesRenmin Zhujiang, 2022
Internal solitary waves represent a common physical phenomenon in water bodies such as oceans,coasts,and estuaries.They are induced by external disturbances on a pycnocline in a stably stratified water body,and the shear flow excited during their ...

Anomalous width variation of rarefactive ion acoustic solitary waves in the context of auroral plasmas [PDF]

open access: yesNonlinear Processes in Geophysics, 2004
The presence of dynamic, large amplitude solitary waves in the auroral regions of space is well known. Since their velocities are of the order of the ion acoustic speed, they may well be considered as being generated from the nonlinear evolution of ion ...

New Types of Nonlinear Waves and Bifurcation Phenomena in Schamel-Korteweg-de Vries Equation

open access: yesAbstract and Applied Analysis, 2013
We study the nonlinear waves described by Schamel-Korteweg-de Vries equation ut+au1/2+buux+δuxxx=0. Two new types of nonlinear waves called compacton-like waves and kink-like waves are displayed.

Propagation of solitary waves through signicantly curved shallow water channels [PDF]

open access: yes, 1998
Propagation of solitary waves in curved shallow water channels of constant depth and width is investigated by carrying out numerical simulations based on the generalized weakly nonlinear and weakly dispersive Boussinesq model.

Construction of Lean Coal Molecular Structure Model Based on Spectroscopic Characterization

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The chemical structure of coal exerts a profound influence on its properties and utilization pathways. A comprehensive analysis of coal's molecular structure is crucial for mitigating environmental pollution arising from coal combustion and improving the efficiency of coal utilization.
