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. WebRayleigh-B nard Convection. : This invaluable book presents a concise but systematic account of the formation of spatial flow structures in a horizontal fluid layer heated from below. Flows of this type, known as Rayleigh-B nard convection, show important features of behaviour inherent not only in various hydrodynamic-instability phenomena but ...
