Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Long-time behavior of Alfven waves in a flowing plasma
阿尔文波 流动 等离子体 长期行为
2023/4/28
In this talk, we consider the long-time behavior of the linearized MHD equations around a steady flowing plasma. We confirm the following physical phenomenon: there will be a generation of a magnetic ...
The International Workshop on Water Waves and Floating Bodies
The International Workshop Water Waves and Floating Bodies
2017/3/28
The International Workshop on Water Waves and Floating Bodies is an annual meeting of mathematicians and engineers with a particular interest in water waves and their effects on floating and submerged...
Liquefaction potential of coastal slopes induced by solitary waves
Coastal slopes Liquefaction Tsunami Wave–seabed interaction
2015/7/1
Tsunami runup and drawdown can cause liquefaction failure of coastal fine sand slopes due to the generation of high excess pore pressure and the reduction of the effective over burden pressure during ...

2015/6/30
Using direct numerical simulations (DNS), we investigate the structure and energetics of breaking internal waves on slopes. We employ a Navier–Stokes code in an idealized three-dimensional domain wher...

Solitary wave peaked crest progressive wave fully nonlinear
2012/4/24
In this paper, a new type of solitary surface waves in a finite water depth is found by analytically solving the fully nonlinear wave equations. Using a new type of base functions which decays exponen...

Modelling rogue waves exact dynamical lump soliton controlled ocean currents Fluid Dynamics
2012/4/26
The ocean rogue wave, one of the mysteries of nature, has not yet been understood or modelled satisfactorily, in spite of being in the intense lime-light in recent years and the concept spreadin fast ...
Energy spectra of gravity and capillary waves with narrow initial excitation
Energy spectra gravity capillary waves narrow initial excitation
2011/8/4
Abstract: In this Letter we present a general method for describing discrete modes' generation in a turbulent wave system with narrow initial excitation. The method is based on the mechanism of modula...

Numerical simulation two-dimensional Faraday waves phase-field modelling
2011/8/3
Abstract: Fully nonlinear numerical simulation of two dimensional Faraday waves between two incompressible and immiscible fluids is performed by adopting the phase-field method with the Cahn-Hilliard ...
Numerical simulations of fully nonlinear equations of motion for long-crested waves at deep water demonstrate that in elongate wave groups the formation of extreme waves occurs most intensively if in ...
Doubly periodic patterns of modulated hydrodynamic waves: exact solutions of the Davey--Stewartson system
Free surface waves Periodic patterns Davey–Stewartson equations
2012/2/29
Exact doubly periodic standing wave patterns of the Davey--Stewartson (DS) equations are derived in terms of rational expressions of elliptic functions. In fluid mechanics, DS equations govern the evo...
