Extreme wave phenomena in down-stream running modulated waves
Andonowati, N. Karjanto, E. van Groesen
Modulational, Benjamin-Feir, instability is studied for the down-stream evolution of surface gravity waves. An explicit solution, the soliton on finite background, of the NLS equat…
Mathematical Physics Properties of Waves on Finite Background
N. Karjanto, E. van Groesen
Several mathematical and physical aspects of waves on finite background are reported in this article. The evolution of the complex wave packet envelope of these type of waves is go…
Qualitative comparisons of experimental results on deterministic freak wave generation based on modulational instability
N. Karjanto, E. van Groesen
A number of qualitative comparisons of experimental results on unidirectional freak wave generation in a hydrodynamic laboratory are presented in this paper. A nonlinear dispersive…
Deterministic aspects of nonlinear modulation instability
E. van Groesen, Andonowati, N. Karjanto
Different from statistical considerations on stochastic wave fields, this paper aims to contribute to the understanding of (some of) the underlying physical phenomena that may give…
Derivation of the NLS breather solutions using displaced phase-amplitude variables
N. Karjanto, E. van Groesen
Breather solutions of the nonlinear Schrödinger equation are derived in this paper: the Soliton on Finite Background, the Ma breather and the rational breather. A special Ansatz of…
Investigation of the maximum amplitude increase from the Benjamin-Feir instability
N. Karjanto, E. van Groesen, P. Peterson
The Nonlinear Schrödinger (NLS) equation is used to model surface waves in wave tanks of hydrodynamic laboratories. Analysis of the linearized NLS equation shows that its harmonic…
