WebRayleigh-Bénard and Bénard-Marangoni convection . In the case of two plates between which a thin liquid layer is placed, only buoyancy is responsible for the appearance of convection cells. This type of convection is called Rayleigh-Bénard convection. The initial movement is the upwelling of warmer liquid from the heated bottom layer.
