Rayleigh droplet formation
WebThe Rayleigh–Plesset equation is often applied to the study of cavitation bubbles, shown here forming behind a propeller. In fluid mechanics, the Rayleigh–Plesset equation or … 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.
