Rayleigh–Bénard convection - Wikipedia
In fluid thermodynamics, Rayleigh–Bénard convection is a type of natural convection, occurring in a planar horizontal layer of fluid heated from below, in which the fluid develops a regular pattern of convection cells known as Bénard cells.

Rayleigh-Bénard Convection - UMD
What is Rayleigh-Bénard convection? Rayleigh-Bénard convection is a buoyancy-driven flow in a container with a temperature gradient. As the fluid at the bottom heats up, its density decreases, so buoyant forces push the less-dense fluid up towards the cooler end of the container.
Rayleigh-Benard Convection - an overview | ScienceDirect Topics
Rayleigh-Bénard convection is defined as a type of geophysical convection where an organized cell structure transitions into a disorganized state as the Rayleigh number increases, leading to fully-developed turbulence.
Rayleigh-Bénard convection - Scholarpedia
2012年10月9日 · Rayleigh - Bénard convection is a fluid flow (thermal convection) due to a non-uniform temperature distribution in a plane horizontal fluid layer heated from below. Such flows result from the development of the convective instability , if the static vertical temperature gradient (the gradient that would be present in a motionless fluid under ...
Rayleigh-Benard Convection - an overview | ScienceDirect Topics
Rayleigh-Benard Convection is defined as the organized movement of a fluid between two thermally conducting plates, where the fluid is heated from below, creating a temperature difference that leads to the formation of convection rolls.
Rayleigh-Benard Cells: NOAA Physical Sciences Laboratory
Rayleigh-Benard Convection Cells This type of convection pattern occurs in a relatively shallow layer - this could mean a layer of fluid 1 millimeter thick in a petri dish, or the first 2 kilometers of the Earth's atmosphere.
Recent Developments in Rayleigh-Bénard Convection
This review summarizes results for Rayleigh-Bénard convection that have been obtained over the past decade or so. It concentrates on convection in compressed gases and gas mixtures with Prandtl numbers near one and smaller.
