Implementation of a fully nonlinear Hamiltonian Coupled-Mode Theory, and application to solitary wave problems over bathymetry
Ch. E. Papoutsellis, A. G. Charalampopoulos, G. A. Athanassoulis
This paper deals with the implementation of a new, efficient, non-perturbative, Hamiltonian coupled-mode theory (HCMT) for the fully nonlinear, potential flow (NLPF) model of water…
A new efficient Hamiltonian approach to the nonlinear water-wave problem over arbitrary bathymetry
Christos Papoutsellis, Gerassimos Athanassoulis
A new Hamiltonian formulation for the fully nonlinear water-wave problem over variable bathymetry is derived, using an exact, vertical series expansion of the velocity potential, i…
Exact semi-separation of variables in waveguides with nonplanar boundaries
Gerassimos A. Athanassoulis, Christos E. Papoutsellis
Series expansions of unknown fields in elongated waveguides are commonly used in acoustics, optics, geophysics, water waves and other applications, in the context o…
