  skos:definition "Une cellule de convection est une zone d'un fluide où celui-ci circule en circuit fermé. Le sens de rotation du fluide est cohérent au sein d'une même cellule, et son déplacement est de même sens de part et d'autre d'une paroi séparant deux cellules adjacentes. (Wikipedia, L'Encylopédie Libre, <a href=\"https://fr.wikipedia.org/wiki/Cellule_de_convection\" target=\"_blank\">https://fr.wikipedia.org/wiki/Cellule_de_convection</a>)"@fr, "In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell. When a volume of fluid is heated, it expands and becomes less dense and thus more buoyant than the surrounding fluid. The colder, denser part of the fluid descends to settle below the warmer, less-dense fluid, and this causes the warmer fluid to rise. Such movement is called convection, and the moving body of liquid is referred to as a convection cell. This particular type of convection, where a horizontal layer of fluid is heated from below, is known as Rayleigh–Bénard convection. Convection usually requires a gravitational field, but in microgravity experiments, thermal convection has been observed without gravitational effects.
