WebDec 10, 2024 · The periodic optical beam transmittance inside the liquid jet exerts time-dependent optical pressure to the jet that triggers the Rayleigh-Plateau instability. The jet breakup process locks in at the frequency corresponding to the peak growth rate of the Rayleigh-Plateau instability of the liquid jet, which agrees with the prediction from the … The Plateau–Rayleigh instability is named for Joseph Plateau and Lord Rayleigh. In 1873, Plateau found experimentally that a vertically falling stream of water will break up into drops if its length is greater than about 3.13 to 3.18 times its diameter, which he noted is close to π. Later, Rayleigh showed theoretically that a … See more The Plateau–Rayleigh instability, often just called the Rayleigh instability, explains why and how a falling stream of fluid breaks up into smaller packets with the same volume but less surface area. It is related to the Rayleigh–Taylor instability See more Water dripping from a faucet/tap 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 … See more • Plateau–Rayleigh Instability – a 3D lattice kinetic Monte Carlo simulation • Savart–Plateau–Rayleigh instability of a water column – Adaptive numerical simulation See more The explanation of this instability begins with the existence of tiny perturbations in the stream.
