As a result of body (volume) and interface (surface) contributions, their velocity is isotropic but inherently strongly dispersive and dependent on the water depth.

WebApr 10, 2024 · The side surface of the jet between the caustics was covered with short ring capillary waves with λ c ∼ 0.1 mm. Capillary waves were observed later at the top of the jet during the pinch-off of secondary drops (with λ c ∼ 0.5 mm) and at the sharp base of the jet when it pinched off from the deformed target fluid (λ c = 0.1–0.15 mm, Fig ...

WebThis corresponds to a completely new type of wave known as a capillary wave. Such waves have wavelengths that are much less than the capillary wavelength. Moreover, Equation ( 11.129) can be rewritten. (11.131) which demonstrates that gravity plays no role in the propagation of a capillary wave. In fact, its place is taken by surface tension.
Webon the time constant in the capillary driven case than the gravitational case. This is because the capillary force depends on curvature, which depends on q 2 while the gravitational force is not affected by the wave number. In both cases, higher wave numbers correspond to faster decay. An arbitrary disturbance can be represented as a
WebAug 26, 2011 · When a drop moves at a constant velocity V on the surface of water, it generates a stationary wake of capillary–gravity waves, provided that V > c min = (4gγ/ρ) 1/4 . This wake can be seen in the magnified view of the moving nitrogen drop in Fig. 2C.
