WebSep 29, 1998 · The Rayleigh capillary instability of a cylindrical interface between two immiscible fluids is one of the most fundamental in fluid dynamics. As Plateau observed from energetic considerations and Rayleigh clarified through hydrodynamics, such an interface is linearly unstable to fission due to surface tension. In traditional descriptions …

WebI. Introduction. The convective instability of a layer of Boussinesq fluids heated uniformly from below is one of the simplest examples of hydrodynamic instability. This phenomenon, known as Rayleigh-Benard (R-B) convection, shows a clear transi-tion from the uniform conduction solution, to a steady motion varying periodically in space. 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 from the faucet, a neck is formed and then stretched.

Neglecting the ambient fluid, the viscosity of the jet liquid, and gravity, he demonstrated that a circular cylindrical liquid jet is unstable with respect to disturbances of wavelengths larger than the jet circumference.
http://silver.neep.wisc.edu/%7Eshock/rtnotes.pdf WebA transonic interaction between a shock wave and a turbulent boundary layer is experimentally and theoretically investigated. The configuration is a transonic channel flow over a bump, where a shock wave causes the separation of the boundary layer in the form of a recirculating bubble downstream of the shock foot.
