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. WebAbstract. After a brief review in the introduction of the major breakthroughs in the study of Rayleigh-Bénard convection (RBC) since the experiments of Henri Bénard, a few selected …
