Rayleigh droplet formation

A special case of this is the formation of small droplets when water is dripping from a faucet/tap. When a segment of water begins to separate from the faucet, a neck is formed and then stretched. If the diameter of the faucet is big enough, the neck does not get sucked back in, and it undergoes a Plateau–Rayleigh instability and collapses into a small droplet. Satellite drops, also known as secondary droplets, are the drops produced during the thread breakup process in addition to the large main droplet. The drops result when the filament by which the main droplet in hanging from the larger fluid mass itself breaks off from the fluid mass. The fluid contained in the filament … See more Fluid thread breakup is the process by which a single mass of fluid breaks into several smaller fluid masses. The process is characterized by the elongation of the fluid mass forming thin, thread-like regions between larger … See more The examination of droplet formation has a long history, first traceable to the work of Leonardo da Vinci who wrote: "How water has … See more Linear stability of inviscid liquids The linear stability of low viscosity liquids was first derived by Plateau in 1873.
