TLDR
In this article, the boundary-value problem for the velocity potential of a wave-maker is solved for both infinite and finite constant depth, and the solution of the corresponding problem concerning the axisymmetric wave motion due to a vertical cylindrical wavemaker is deduced in conclusion.Abstract:
The classical wave-maker problem to determine the forced two-dimensional wave motion with outgoing surface waves at infinity generated by a harmonically oscillating vertical plane wave-maker immersed in water was solved long ago by Sir Thomas Havelock. In this paper we reinvestigate the problem, making allowance for the presence of surface tension which was excluded before, and obtain a solution of the boundary-value problem for the velocity potential which is made unique by prescribing the free surface slope at the wave-maker. The cases of both infinite and finite constant depth are treated, and it is essential to employ a method which is new to this problem since the theory of Havelock cannot be extended in the latter case of finite depth. The solution of the corresponding problem concerning the axisymmetric wave motion due to a vertical cylindrical wave-maker is deduced in conclusion.read more

Expansion formulae in wave structure interaction problems
TL;DR: In this paper, mode-coupling relations are derived by utilizing the Fourier integral theorem for the solutions of the Laplace equation with higher-order derivatives in the boundary conditions in both the cases of a semi-infinite strip and a semiinfinite domain in two dimensions.

Capillary-gravity waves produced by a wavemaker
L. M. Hocking,D. Mahdmina +1 more
TL;DR: In this article, the amplitude and frequency of the waves depend on both surface tension and gravity, as well as on the condition imposed at the contact line between the free surface and the wavemaker.

Oblique scattering of gravity waves by moored floating membrane with changes in bottom topography
TL;DR: In this paper, the interaction of an incident wave with a moored floating membrane as a breakwater is analyzed for both the cases of finite water depth and shallow water approximation based on the linearized water wave theory, including the effect of changes in bottom topography.

Fundamental singularities in the theory of water waves with surface tension
TL;DR: In this paper, the authors obtained the forms for the harmonic potential functions describing the fundamental wave-source and multipole singularities which pertain to the study of infinitesimal time-harmonic waves on the free surface of water when the effect of surface tension is included.

Forced capillary-gravity waves in a circular basin
M.C. Shen,S. M. Sun,D.Y. Hsieh +2 more
TL;DR: In this article, a linear theory was developed to study the forced capillary-gravity waves generated on water in a circular basin by the horizontal oscillations of its side wall, and a Green's function method was used to construct a solution of the linearized equations subject to an edge condition at the contact line.

The effect of surface tension on the waves produced by a heaving circular cylinder
TL;DR: In this article, the effect of surface tension on water waves is considered and a uniqueness theorem is derived for the waves at infinity for a general class of bounded two-dimensional obstacles in a free surface by means of an energy argument.
