capillary wave

[′kap·ə‚ler·ē ‚wāv]
(fluid mechanics)
A wave occurring at the interface between two fluids, such as the interface between air and water on oceans and lakes, in which the principal restoring force is controlled by surface tension.

As for capillary wave, its dispersion relation is decided by surface tension and can be expressed as [[omega].
First, hydrodynamic instability sets in giving rise to wavy interfaces; as the disturbance grows, the fiber breaks up into drops; this is the capillary wave mechanism.
Kwoh and Lake also suggested that the dominant scattering from the wave crest could be approximated by wedge scattering and analyzed the relationship of scattering fields from capillary wave and the wedge-shaped crest with small perturbation method (SPM) and geometrical theory of diffraction (GTD) respectively [25].

Thermal capillary waves cause fluid droplets to coalesce with a fluid substrate by film drainage at the interface, breakage of the film, and intrusion of the particle into the bulk phase (Aarts et al.
