unusual facts about Rayleigh–Taylor instability


Rayleigh–Taylor instability

The equilibrium here is unstable to any perturbations or disturbances of the interface: if a parcel of heavier fluid is displaced downward with an equal volume of lighter fluid displaced upwards, the potential energy of the configuration is lower than the initial state.


Asbestos Testing and Consultancy Association

The head office is in Burton and there is a training centre in Rayleigh, the association also has access to various other training centres across the UK.

Clements Hall Leisure Centre

Virgin Active also manage other sites in the area: Rayleigh Leisure Centre and Great Wakering Leisure Centre; as well as two events centres: The Mill and The Freight House.

Greensward Academy

Opened in 1960 as the Hockley County Secondary School, with pupils from both Hockley and Ashingdon primary schools who were selected for the first year and a second year of Hockley pupils who previously went to Rayleigh Secondary.

Helmholtz reciprocity

Rayleigh stated the basic idea of reciprocity as a consequence of the linearity of propagation of small vibrations, light consisting of sinusoidal vibrations in a linear medium.

Masters Performing Arts College

Masters Performing Arts College is an independent performing arts college, based in the town of Rayleigh in Essex, England.

Optical resolution

Rayleigh defined the somewhat arbitrary "Rayleigh criterion" that two points whose angular separation is equal to the Airy disk radius to first null can be considered to be resolved.

Production Systems Engineering

Weibull, Rayleigh, gamma, and log-normal probability density functions (time-dependent breakdown and repair rates): no Markov descriptions is available;

Rayleigh, Essex

The Dutch Cottage, the smallest and oldest council house in the United Kingdom, can be visited on Wednesdays by prior appointment.

Thin film

Through the influence of electric field, the liquid coming out of the nozzle takes a conical shape (Taylor cone) and at the apex of the cone a thin jet emanates which disintegrates into very fine and small positively charged droplets under the influence of Rayleigh charge limt.

Transient kinetic isotope fractionation

Transient kinetic isotope effects (or fractionation) occur when the reaction leading to isotope fractionation does not follow pure first-order kinetics and therefore isotopic effects cannot be described with the classical equilibrium fractionation equations or with steady-state kinetic fractionation equations (also known as the Rayleigh equation).

Ultraviolet catastrophe

The term "ultraviolet catastrophe" was first used in 1911 by Paul Ehrenfest, although the concept goes back to 1900 with the first derivation of the \lambda^{-4} dependence of the Rayleigh–Jeans law; the word "ultraviolet" refers to the fact that the problem appears in the short wavelength region of the electromagnetic spectrum.

Vlasov equation

# Theory of pair collisions disagrees with the discovery by Rayleigh, Irving Langmuir and Lewi Tonks of natural vibrations in electron plasma.

Wave field synthesis

According to Rayleigh II the sound pressure is determined in each point of a half-space, if the sound pressure in each point of its dividing plane is known.
