WebDec 24, 2012 · A typical droplet formation sequence in the dripping-plug regime is shown in Fig. 3 and could be stated as follows: first, after the final pinch-off of a droplet, the dispersed thread retracts due to surface tension and the newly formed droplet moves towards the outlet, followed by a much smaller satellite droplet (Fig. 3 a and b); second, the dispersed …
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. WebSep 5, 2024 · Although the Rayleigh–Plateau instability is responsible for the pinch-off, the formation of the neck and therefore the final droplet diameter is controlled by the initial …
