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
