See all on Wikipediahttps://en.wikipedia.org/wiki/ConvectionConvection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of … See more
The word convection has different but related usages in different scientific or engineering contexts or applications. The broader sense is in fluid mechanics, where convection refers to the motion of fluid driven by density … See more

Convection, especially Rayleigh–Bénard convection, where the convecting fluid is contained by two rigid horizontal plates, is a convenient example of a pattern-forming system.
When heat is fed into the system from one direction (usually … See moreSystems of natural circulation include tornadoes and other weather systems, ocean currents, and household ventilation. Some solar water heaters use natural circulation. The See more
One example of natural convection is heat transfer from an isothermal vertical plate immersed in a fluid, causing the fluid to move parallel to the plate. This will occur in any system wherein the density of the moving fluid varies with position. These phenomena will … See more

- La convection est le mouvement interne d'un fluide sous l'effet de la différence de température, de salinité ou d'une autre caractéristique entre deux endroits[2]. Elle peut être induite naturellement ou forcée. Il faut la différencier de l'advection qui est la quantité d'énergie, de salinité ou d'une autre caractéristique du fluide transportée par...
