Solitary waves travelling along an unsmooth boundary
Results in Physics, 2021 It is well-known that the boundary conditions will greatly affect the wave shape of a nonlinear wave equation. This paper reveals that the peak of a solitary wave is weakly affected by the unsmooth boundary.

Nonexistence of Subcritical Solitary Waves [PDF]
Archive for Rational Mechanics and Analysis, 2021 AbstractWe prove the nonexistence of two-dimensional solitary gravity water waves with subcritical wave speeds and an arbitrary distribution of vorticity. This is a longstanding open problem, and even in the irrotational case there are only partial results relying on sign conditions or smallness assumptions.

Numerical Simulation for the Evolution of Internal Solitary Waves Propagating over Slope Topography
Journal of Marine Science and Engineering, 2021 In this study, the propagation and evolution characteristics of internal solitary waves on slope topography in stratified fluids were investigated. A numerical model of internal solitary wave propagation based on the nonlinear potential flow theory using

Results in Physics, 2021 We find analytically an exact soliton-like solution of cubic-quintic nonlinear Schrödinger equation (CQNLSE) with pure normal fourth-order dispersion (FOD). This exact solitary solution is “fixed-parameter” solitary wave, whose waveform is well described

Three-Dimensional Simulations of Offshore Oil Platform in Square and Diamond Arrangements
Advances in Mathematical Physics, 2021 The interaction of the solitary wave with an oil platform composed of four vertical circular cylinders is investigated for two attack angle of the solitary wave β=0° (square arrangement) and β=45° (diamond arrangement).

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.

Proceedings of the National Academy of Sciences, 1980 Transversely periodic solitary-wave solutions of the Boussinesq equations (which govern wave propagation in a weakly dispersive, weakly nonlinear physical system) are determined. The solutions for negative dispersion (e.g., gravity waves) are singular and therefore physically unacceptable. The solutions for positive dispersion (e.g., capillary waves or
