Stability of gravity-capillary waves generated by a moving pressure disturbance in water of finite depth

In previous work, we investigated two-dimensional steady gravity-capillary waves generated by a localized pressure distribution moving with constant speed U in water of finite depth h . Localized solitary waves can only exist in subcritical flows where the Froude number F = U/(gh) < 1 , and were found using a combination of numerical simulations of the fully nonlinear inviscid, irrotational equ...

Capillary-gravity waves generated by a slow moving object.

We investigate theoretically and experimentally the capillary-gravity waves created by a small object moving steadily at the water-air interface along a circular trajectory. It is well established that, for straight uniform motion, no steady waves appear at velocities below the minimum phase velocity c(min)=23 cm s(-1). We demonstrate that no such velocity threshold exists for a steady circular...

Three-dimensional travelling gravity-capillary water waves

1.1 The hydrodynamic problem The classical water-wave problem concerns the irrotational flow of a perfect fluid of unit density subject to the forces of gravity and surface tension. The fluid motion is described by the Euler equations in a domain bounded below by a rigid horizontal bottom {y = −h} and above by a free surface which is described as a graph {y = η(x, z, t)}, where the function η d...

Gravity-capillary lumps generated by a moving pressure source.

The nonlinear wave pattern generated by a localized pressure source moving over a liquid free surface at speeds below the minimum phase speed (c{min}) of linear gravity-capillary waves is investigated experimentally and theoretically. At these speeds, freely propagating fully localized solitary waves, or "lumps," are known theoretically to be possible. For pressure-source speeds far below c{min...

Three-dimensional Solitary Gravity-capillary Water Waves

The existence of solitary-wave solutions to the three-dimensional water-wave problem with strong surface-tension effects is predicted by the KP-I model equation. The term solitary wave describes any solution which has a pulse-like profile in its direction of propagation, and the KP-I equation admits explicit solutions for three different types of solitary wave. A line solitary wave is spatially...
