Rayleigh-bernard对流
http://html.rhhz.net/SYLTLX/html/2015-4-47.htm 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 case of a free liquid surface in contact with air, buoyancy and surface tension effects will also play a role in how the convection patterns develop. Liquids flow from places of lower … See more • Hydrodynamic stability • Marangoni effect • Natural convection See more • A. Getling, O. Brausch: Cellular flow patterns • K. Daniels, B. Plapp, W.Pesch, O. Brausch, E. Bodenschatz: Undulation Chaos in inclined Layer Convection See more Since there is a density gradient between the top and the bottom plate, gravity acts trying to pull the cooler, denser liquid from the top to the bottom. This gravitational force is opposed by the viscous damping force in the fluid. The balance of these two forces is expressed … 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).
