The famous example of a dripping faucet is an example of a Rayleigh-Plateau instability in which there is a certain jet radius below which perturbations on the surface will grow to break the jet into droplets. The drop radius, according to this theory, can be predicted by calculating the fastest growing unstable wavelength.
In practice you often have small satellite droplets after the 'main' droplet, see below
What I wonder is how it is possible that these satellite droplets occur in a breaking jet? Something which, as far as I understand, is not predicted by Rayleigh-Plateau theory.
Does this have to do with the fact that Rayleigh-Plateau theory is only applicable to the onset of breakup? Or is it for example caused by inertial or viscous effects?
