**Rayleigh number**— In fluid mechanics, the Rayleigh number for a fluid is a dimensionless number associated with buoyancy driven flow (also known as free convection or natural convection). When the Rayleigh number is below the critical value for that fluid, heat… … Wikipedia**Rayleigh**— may refer to:*Rayleigh (unit), named after the son of Lord Rayleigh *Rayleigh criterion in Angular resolution *Rayleigh distribution *Rayleigh fading *Rayleigh law on low field magnetization *Rayleigh length *Rayleigh number *Rayleigh quotient… … Wikipedia**Rayleigh–Bénard convection**— Bénard cells. Rayleigh–Bénard convection is a type of natural convection, occurring in a plane of fluid heated from below, in which the fluid develops a regular pattern of convection cells known as Bénard cells. Rayleigh–Bénard convection is one… … Wikipedia**Rayleigh flow**— refers to diabatic flow through a constant area duct where the effect of heat addition or rejection is considered. Compressibility effects often come into consideration, although the Rayleigh flow model certainly also applies to incompressible… … Wikipedia**Rayleigh wave**— Rayleigh waves, also known as the Rayleigh Lamb Wave or ground roll , are a type of surface wave. They are associated on the Earth with earthquakes and subterranean movement of magma, or with any other source of seismic energy, such as an… … Wikipedia**Rayleigh fading**— is a statistical model for the effect of a propagation environment on a radio signal, such as that used by wireless devices.Rayleigh fading models assume that the magnitude of a signal that has passed through such a transmission medium (also… … Wikipedia**Rayleigh, Essex**— infobox UK place country = England official name= Rayleigh static latitude= 51.5864longitude= 0.6049os grid reference= TQ805907 population = 34,000 shire district= Rochford shire county = Essex region= East of Englandconstituency westminster=… … Wikipedia**Rayleigh–Taylor instability**— The Rayleigh–Taylor instability, or RT instability (after Lord Rayleigh and G.
