Rayleigh-bénard convection
WebMany variations on this process have been studied in the laboratory since Bénard's first experiments around the turn of the century. The onset of convection is the archetypal example of a pattern forming instability. This simplest and most studied version is Rayleigh-Bénard convection, shown schematically below. 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. Bénard–Rayleigh convection is one of the most commonly … See more The features of Bénard convection can be obtained by a simple experiment first conducted by Henri Bénard, a French physicist, in 1900. Development of convection The experimental … See more In 1870, the Irish-Scottish physicist and engineer James Thomson (1822–1892), elder brother of Lord Kelvin, observed water cooling in a tub; he noted that the soapy film on the water's surface was divided as if the surface had been tiled (tesselated).
