Development of a two-dimensional numerical wave tank

TLDR: In this article, a two-dimensional numerical wave tank has been developed using a boundary integral scheme, where waves are generated by a hinged "wave-maker" at one end of the "wave flume" and they are absorbed by a "damper" at the other end.

Abstract: A two-dimensional numerical wave tank has been developed using a boundary integral scheme. Waves are generated by a hinged "wave-maker" at one end of the "wave flume" and they are absorbed by a "damper" at the other end. In deep water,m the wave forms are solely determined by the motion of the wave-maker. A single-frequency sinusoidal motion of the paddle results in a steady progressive wave of the same frequency. Starting from the still- water condition, the first few waves are seen to disappear as they travel towards the other end of the tank, which is exactly what happens in a real wave flume. Comparisons between Stokes wave kinematics and that of monochromatic waves generated in the numerical wave tank have been carried out and the results are in good agreement with experimental observations.
